      “People are excited and happy about working at Goddard,” said optics engineer Margaret Dominguez. “Most people are willing to put in the extra effort if needed. It makes work stimulating and exciting. Management really cares and the employees feel that too.”Credits: Courtesy of Margaret Dominguez Name: Margaret Dominguez
      Formal Job Classification: Optical engineer
      Organization: Code 551, Optics Branch, Instrument Systems and Technology Division, Engineering Directorate
      What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission?
      I build space telescopes. I am currently working on building one of the components for the Wide Field Instrument for the Roman Space Telescope. The component is called “Grism.” A grism is a combination of a grating and a prism.
      What is unique about your childhood?
      I went to high school in Tecamachalco in Puebla, Mexico, which is inland and south of Mexico City. My father raised pigs, chickens, rabbits, and cows. I am the oldest of four girls and two still live on the farm.
      Why did you become a physicist?
      I was always curious and had a lot of questions and thought that physics helped me answer some of these questions. I was good at math and loved it. When I told my dad I wanted to study physics, he said that I would be able to answer any question in the universe. He thought it was very cool.
      What is your educational background? How an internship help you come to Goddard?
      I went to the Universidad de las Americas Puebla college in Puebla and got an undergraduate degree in physics. I was very active in extracurricular activities and helped organize a physics conference. We invited Dr. Johnathan Gardner, a Goddard astronomer, who came to speak at the conference. Afterwards I spoke with him and he asked me if I was interested in doing an internship at NASA. I said I had not considered it and would be interested in applying. I applied that same spring of 2008 and got a summer internship in the Optics Branch, where I am still working today.
      My branch head at Goddard was a University of Arizona alumnus. He suggested that I apply to the University of Arizona for their excellent optics program. I did, and the university gave me a full fellowship for a master’s and a Ph.D. in optical sciences.
      In 2014, I began working full time at Goddard while completing my Ph.D. I graduated in May 2019.
      What makes Goddard special?
      Goddard has a university campus feel. It’s a place where you can work and also just hang out and socialize. Goddard has many clubs, a gym, cafeterias, and a health clinic.
      People are really nice here. They are often excited and happy about working at Goddard. Most people are willing to put in the extra effort if needed. It makes work stimulating and exciting. Management really cares and the employees feel that too.
      What are some of the major projects you have worked on?
      Early on, I did a little bit of work on Hubble and later on, NASA’s James Webb Space Telescope. Since 2014, I have exclusively been working on Roman. We are building the grism, a slitless spectrograph, which will measure galaxy redshifts to study dark energy.
      Presently we are building different grism prototypes. We work with outside vendors to build these prototypes. When we make a prototype, we test it for months. After, we use the results to build an improved prototype. We just finished making the third prototype. We are going to build a flight instrument of which the grism is a component.
      What is it like to work in the clean room?
      It’s exciting – it likely means I am working on flight hardware. However, because clean rooms must be kept at about 68 degrees Fahrenheit, it can feel chilly in there!
      Who are your mentors? What are the most important lessons they have taught you?
      Ray Ohl, the head of the Optics Branch, is a mentor to me. He is always encouraging me to get outside my comfort zone. He presents other opportunities to me so that I can grow and listens to my feedback.
      Cathy Marx, one of the Roman optical leads, is also a mentor to me. She created a support network for me and is a sounding board for troubleshooting any kind of work-related issues.
      What is your role a member of the Hispanic Advisory Committee (HACE)?
      I joined HACE in 2010 while I was an intern. It’s a great opportunity to network with other Hispanics and gives us a platform to celebrate specific events like Hispanic Heritage Month. I really enjoy participating in HACE’s events.
      What outreach do you do? Why is doing outreach so important to you?
      I do educational outreach to teach people about optics. I mainly collaborate with elementary and middle schools.
      I think we need more future engineers and scientists. I want to help recruit them. I specifically focus on recruiting minorities and Hispanics. I can make a special connection with women and Hispanics.
      Who is your science hero?
      It would probably be Marie Curie. She’s the first woman to win a Nobel Prize, and she is the only woman to win two Nobel Prizes and she had to overcome a lot of challenges to achieve that.
      What is your “six-word memoir”? A six-word memoir describes something in just six words.
      Disciplined. Organized. Diligent. Passionate. Curious. Family-oriented.
      Is there something surprising about your hobbies outside of work that people do not generally know?
      I am a certified Jazzercise instructor – I normally teach two to three times a week. I can even teach virtually if need be. It is an hour-long exercise class combining strength training and cardio through choreographed dancing. We also use weights and mats.  
      I also enjoy going for walks with my husband, James Corsetti, who is also an engineer in the Optics Branch.

      International teams of astronomers monitoring a supermassive black hole in the heart of a distant galaxy have detected features never seen before using data from NASA missions and other facilities. The features include the launch of a plasma jet moving at nearly one-third the speed of light and unusual, rapid X-ray fluctuations likely arising from near the very edge of the black hole.
      Radio images of 1ES 1927+654 reveal emerging structures that appear to be jets of plasma erupting from both sides of the galaxy’s central black hole following a strong radio flare. The first image, taken in June 2023, shows no sign of the jet, possibly because hot gas screened it from view. Then, starting in February 2024, the features emerge and expand away from the galaxy’s center, covering a total distance of about half a light-year as measured from the center of each structure. NSF/AUI/NSF NRAO/Meyer at al. 2025 The source is 1ES 1927+654, a galaxy located about 270 million light-years away in the constellation Draco. It harbors a central black hole with a mass equivalent to about 1.4 million Suns.
      “In 2018, the black hole began changing its properties right before our eyes, with a major optical, ultraviolet, and X-ray outburst,” said Eileen Meyer, an associate professor at UMBC (University of Maryland Baltimore County). “Many teams have been keeping a close eye on it ever since.”
      She presented her team’s findings at the 245th meeting of the American Astronomical Society in National Harbor, Maryland. A paper led by Meyer describing the radio results was published Jan. 13 in The Astrophysical Journal Letters.
      After the outburst, the black hole appeared to return to a quiet state, with a lull in activity for nearly a year. But by April 2023, a team led by Sibasish Laha at UMBC and NASA’s Goddard Space Flight Center in Greenbelt, Maryland, had noted a steady, months-long increase in low-energy X-rays in measurements by NASA’s Neil Gehrels Swift Observatory and NICER (Neutron star Interior Composition Explorer) telescope on the International Space Station. This monitoring program, which also includes observations from NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array) and ESA’s (European Space Agency) XMM-Newton mission, continues.
      The increase in X-rays triggered the UMBC team to make new radio observations, which indicated a strong and highly unusual radio flare was underway. The scientists then began intensive observations using the NRAO’s (National Radio Astronomy Observatory) VLBA (Very Long Baseline Array) and other facilities. The VLBA, a network of radio telescopes spread across the U.S., combines signals from individual dishes to create what amounts to a powerful, high-resolution radio camera. This allows the VLBA to detect features less than a light-year across at 1ES 1927+654’s distance.
      Active galaxy 1ES 1927+654, circled, has exhibited extraordinary changes since 2018, when a major outburst occurred in visible, ultraviolet, and X-ray light. The galaxy harbors a central black hole weighing about 1.4 million solar masses and is located 270 million light-years away. Pan-STARRS Radio data from February, April, and May 2024 reveals what appear to be jets of ionized gas, or plasma, extending from either side of the black hole, with a total size of about half a light-year. Astronomers have long puzzled over why only a fraction of monster black holes produce powerful plasma jets, and these observations may provide critical clues.
      “The launch of a black hole jet has never been observed before in real time,” Meyer noted. “We think the outflow began earlier, when the X-rays increased prior to the radio flare, and the jet was screened from our view by hot gas until it broke out early last year.”
      A paper exploring that possibility, led by Laha, is under review at The Astrophysical Journal. Both Meyer and Megan Masterson, a doctoral candidate at the Massachusetts Institute of Technology in Cambridge who also presented at the meeting, are co-authors.
      Using XMM-Newton observations, Masterson found that the black hole exhibited extremely rapid X-ray variations between July 2022 and March 2024. During this period, the X-ray brightness repeatedly rose and fell by 10% every few minutes. Such changes, called millihertz quasiperiodic oscillations, are difficult to detect around supermassive black holes and have been observed in only a handful of systems to date. 
      “One way to produce these oscillations is with an object orbiting within the black hole’s accretion disk. In this scenario, each rise and fall of the X-rays represents one orbital cycle,” Masterson said.  
      If the fluctuations were caused by an orbiting mass, then the period would shorten as the object fell ever closer to the black hole’s event horizon, the point of no return. Orbiting masses generate ripples in space-time called gravitational waves. These waves drain away orbital energy, bringing the object closer to the black hole, increasing its speed, and shortening its orbital period.
      Over two years, the fluctuation period dropped from 18 minutes to just 7 — the first-ever measurement of its kind around a supermassive black hole. If this represented an orbiting object, it was now moving at half the speed of light. Then something unexpected happened — the fluctuation period stabilized.
      In this artist’s concept, matter is stripped from a white dwarf (sphere at lower right) orbiting within the innermost accretion disk surrounding 1ES 1927+654’s supermassive black hole. Astronomers developed this scenario to explain the evolution of rapid X-ray oscillations detected by ESA’s (European Space Agency) XMM-Newton satellite. ESA’s LISA (Laser Interferometer Space Antenna) mission, due to launch in the next decade, should be able to confirm the presence of an orbiting white dwarf by detecting the gravitational waves it produces. NASA/Aurore Simonnet, Sonoma State University “We were shocked by this at first,” Masterson explained. “But we realized that as the object moved closer to the black hole, its strong gravitational pull could begin to strip matter from the companion. This mass loss could offset the energy removed by gravitational waves, halting the companion’s inward motion.”
      So what could this companion be? A small black hole would plunge straight in, and a normal star would quickly be torn apart by the tidal forces near the monster black hole. But the team found that a low-mass white dwarf — a stellar remnant about as large as Earth — could remain intact close to the black hole’s event horizon while shedding some of its matter. A paper led by Masterson summarizing these results will appear in the Feb. 13 edition of the journal Nature.
      This model makes a key prediction, Masterson notes. If the black hole does have a white dwarf companion, the gravitational waves it produces will be detectable by LISA (Laser Interferometer Space Antenna), an ESA mission in partnership with NASA that is expected to launch in the next decade.

      This illustration shows a red, early-universe dwarf galaxy that hosts a rapidly feeding black hole at its center. Using data from NASA’s James Webb Space Telescope and Chandra X-ray Observatory, a team of astronomers have discovered this low-mass supermassive black hole at the center of a galaxy just 1.5 billion years after the Big Bang. It is pulling in matter at a phenomenal rate — over 40 times the theoretical limit. While short lived, this black hole’s “feast” could help astronomers explain how supermassive black holes grew so quickly in the early universe.NOIRLab/NSF/AURA/J. da Silva/M. Zamani A rapidly feeding black hole at the center of a dwarf galaxy in the early universe, shown in this artist’s concept, may hold important clues to the evolution of supermassive black holes in general.
      Using data from NASA’s James Webb Space Telescope and Chandra X-ray Observatory, a team of astronomers discovered this low-mass supermassive black hole just 1.5 billion years after the big bang. The black hole is pulling in matter at a phenomenal rate — over 40 times the theoretical limit. While short lived, this black hole’s “feast” could help astronomers explain how supermassive black holes grew so quickly in the early universe.
      Supermassive black holes exist at the center of most galaxies, and modern telescopes continue to observe them at surprisingly early times in the universe’s evolution. It’s difficult to understand how these black holes were able to grow so big so rapidly. But with the discovery of a low-mass supermassive black hole feasting on material at an extreme rate so soon after the birth of the universe, astronomers now have valuable new insights into the mechanisms of rapidly growing black holes in the early universe.
      The black hole, called LID-568, was hidden among thousands of objects in the Chandra X-ray Observatory’s COSMOS legacy survey, a catalog resulting from some 4.6 million Chandra observations. This population of galaxies is very bright in the X-ray light, but invisible in optical and previous near-infrared observations. By following up with Webb, astronomers could use the observatory’s unique infrared sensitivity to detect these faint counterpart emissions, which led to the discovery of the black hole.
      The speed and size of these outflows led the team to infer that a substantial fraction of the mass growth of LID-568 may have occurred in a single episode of rapid accretion.
      LID-568 appears to be feeding on matter at a rate 40 times its Eddington limit. This limit relates to the maximum amount of light that material surrounding a black hole can emit, as well as how fast it can absorb matter, such that its inward gravitational force and outward pressure generated from the heat of the compressed, infalling matter remain in balance.
      These results provide new insights into the formation of supermassive black holes from smaller black hole “seeds,” which current theories suggest arise either from the death of the universe’s first stars (light seeds) or the direct collapse of gas clouds (heavy seeds). Until now, these theories lacked observational confirmation.
      The new discovery suggests that “a significant portion of mass growth can occur during a single episode of rapid feeding, regardless of whether the black hole originated from a light or heavy seed,” said International Gemini Observatory/NSF NOIRLab astronomer Hyewon Suh, who led the research team.
      A paper describing these results (“A super-Eddington-accreting black hole ~1.5 Gyr after the Big Bang observed with JWST”) appears in the journal Nature Astronomy.

      Although surrounded by the big and bold missions of human spaceflight, Margaret Kennedy, an aerospace systems engineer on the Human Health and Performance Contract, still appreciates the little things. Ask about her favorite NASA experience to date and she will tell you it is getting to show her badge to the gate guards at Houston’s Johnson Space Center every day. “Knowing I get to be a part of things that can change the world – that I’m helping to make it possible for astronauts to do their job safely, which in turn supports life on Earth – is very rewarding,” she said.

      Margaret Kennedy poses with Johnson Space Center’s inflatable mascot, Cosmo, at Comicpalooza 2024 in Houston, Texas. Image courtesy of Margaret Kennedy Kennedy joined the Johnson team as a contractor with Aegis Aerospace in October 2019. Since then, she has spent most of her time as a systems engineer for the Human Research Program’s Program Integration and Strategic Planning group. That role required her to collect technical information for various projects and to ensure systems were in place to correctly track and manage program documents and agreements. This spring, Kennedy transitioned to a new role in which she provides systems engineering for flight hardware supporting Gateway and exploration missions to the Moon and Mars.

      She started engaging with Johnson’s Employee Resource Groups (ERGs) shortly before the COVID-19 pandemic and jumped at the chance to get more involved once employees came back onsite. “A few people have been surprised when I tell them I’m really an introvert, not an extrovert, but I had to get out of my shell or I’d still be stuck in my apartment,” she said. “The ERGs were a way for me get out of my space and have allowed me to grow.”

      Kennedy is thankful the Johnson Parenting ERG started allowing contractors to serve as secretaries because that led to similar opportunities with other ERGs. She served as the membership secretary for both Emerge and Out & Allied ERG (OAERG) in 2023 and is currently OAERG’s executive secretary. “I help keep our chair and co-chair up to date,” she said. “I have my finger on everything that’s happening in the ERG.” Filling these roles gives Kennedy numerous opportunities to support diversity, equity, and inclusion at Johnson, the most recent of which was her participation on a panel during the center’s Diversity, Equity, Inclusion, and Accessibility Day.  

      Margaret Kennedy (left) participates in a panel discussion during Johnson Space Center’s 2024 Diversity, Equity, Inclusion, and Accessibility Day with Kent Kalogera, Out & Allied ERG chair, Livette Santiago Cardona, Greening and Restoring Our World ERG chair, Andrea Browne, African American ERG chair, and Anika Isaac, Employee Assistance Program counselor.NASA/Robert Markowitz “The main advice I’d give to others wanting to get involved is find your people and don’t be afraid to take a risk,” she said. “Many of us deal with risk every day in our work so find a way to buy down risk by finding allies and a support system. Even if you only get a hair’s width outside your zone of comfort, it makes a difference.”

      She also said that simply participating in ERG meetings and events – whether in person or virtually – is another great way to get involved. “The ERGs can’t do what we do without you,” she said. “We do it because it’s important to us and to others, but we sometimes struggle to know what people want. We need your thoughts and your ideas because it helps us provide programming and inform the center about what is happening.”

      Being a part of OAERG in particular has helped Kennedy personally and professionally. “It has provided me with a space to be my authentic self and bring that person to both the world and work,” she said. “In the long line of LGBTQI+ letter soup, I end up in the + on the end more times than not. Out & Allied has given me a way to not only embrace my identity but also help spread awareness about it.” Professionally, the ERG has helped her network with a range of people, including upper and middle management, and strengthen her communication, problem solving, and leadership skills.

      Margaret Kennedy (center) volunteering at a Hatch Youth event in Houston, Texas, with Kent Kalogera, Out & Allied ERG chair, and Chasity Williams, the group’s former chair. Image courtesy of Margaret Kennedy Kennedy acknowledged that change can take time, noting that while Johnson’s safety-oriented culture is a strength, it can sometimes slow the pace of initiatives that may not be considered mission critical, as can staffing shortages in some areas. “Things like accessible walkways and gender-neutral bathrooms are still important,” she said, adding that leadership is working on it.
      Kennedy encourages everyone at Johnson to check in with their teammates and have “water cooler moments” with their colleagues as a way of promoting inclusivity. “Be patient and willing to give everyone some grace,” she said. “We can get so focused on the mission and what we need that we sometimes forget there are things happening in other people’s lives that can affect their work.”
