Marc Rafelski

 

Dr. Marc Rafelski is the Wide Field Camera 3 (WFC3) branch deputy for the Hubble Space Telescope (HST). Previously he worked with the Mikulski Archive for Space Telescopes (MAST) and the Cosmic Origins Spectrograph (COS) on HST. For MAST he worked on initiatives to improve support for spectroscopic data. For COS he was the lead for the front end and calibration of the 4th lifetime position, user support deputy, and editor of the COS Data Handbook.

Dr. Rafelski's research aims to further our understanding of the formation and evolution of galaxies by studying the physical characteristics and processes of high redshift galaxies and their associated gas reservoirs, inflows, and outflows. He has been working on this via chemical abundance and star formation studies of quasar absorption line systems, which provide a unique laboratory for understanding the conversion of cold gas into stars at high redshift. He also studies the galaxies directly in emission, learning about their star-formation and resolved structure from high-resolution ultraviolet imaging and their physical properties via low-resolution grism spectroscopy.

Dr. Rafelski has used a wide range of telescopes both from the ground and space covering the ultraviolet through infrared wavelengths, using over 15 instruments for imaging and spectroscopy on more than 6 telescopes. He is an active member of the research community and has published more than 60 peer-reviewed articles, which have appeared in the Astronomical Journal, the Astrophysical Journal, the Monthly Notices of the Royal Astronomical Society, and Astrophysics and Space Science Library journals. He regularly presents at conferences and meetings, including more than 50 around the world. Dr. Rafelski is also affiliated as an Associate Research Scientist at Johns Hopkins University.
