NASA Awards Astrophysics Postdoctoral Fellowships for 2023

Newswise — NASA has selected 24 new Fellows for its prestigious NASA Hubble Fellowship Program (NHFP). The NHFP is one of the highlights of NASA's pursuit of excellence in astrophysics. The program enables outstanding postdoctoral scientists to pursue independent research in any area of NASA Astrophysics, using theory, observations, simulations, experimentation, or instrument development. Over 450 applicants vied for the 2023 fellowships. Each fellowship provides the awardee up to three years of support.

Once selected, fellows are named to one of three sub-categories corresponding to three broad scientific questions that NASA seeks to answer about the universe:

• How does the universe work? – Einstein Fellows
• How did we get here? – Hubble Fellows
• Are we alone? – Sagan Fellows

"Congratulations to this year’s Fellows, who have all proposed inspiring research programs that speak to the excitement and opportunity of this era in astrophysics," said Mark Clampin, director of the Astrophysics Division at NASA Headquarters in Washington. "I look forward to seeing their discoveries shape our knowledge of the universe."

The newly selected NHFP Fellows will begin their programs in the fall of 2023 at a university or research center of their choosing in the United States. The list below provides the names of the 2023 awardees, their fellowship host institutions, and their proposed research topics.

• Margaret (Maggie) Thompson, Carnegie Institution for Science's Earth and Planets Laboratory, To Explore Strange New Worlds: Connecting the Interiors and Atmospheres of Rocky Exoplanets

An important part of the NHFP is the annual Symposium, which allow Fellows the opportunity to present results of their research, and to meet each other and the scientific and administrative staff who manage the program. A lively and very successful hybrid symposium was held at the Space Telescope Science Institute in Baltimore, Maryland in the fall of 2022, which included a session in which the fellows discussed their scientific research and plans to increase diversity, equity, and inclusion in the NHFP, as well as participated in a career panel.

The Space Telescope Science Institute administers the NHFP on behalf of NASA, in collaboration with the Chandra X-ray Center at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, and the NASA Exoplanet Science Institute at Caltech/IPAC in Pasadena, California.
