Dr. Joel Bregman

Biography

Joel Bregman is the H.D. Curtis Professor of Astronomy at the University of Michigan. His research focuses on cosmology, extragalactic and galactic astrophysics, and extreme astrophysics, with a particular interest in the theory of X-ray observations. Bregman is known for his work on the missing baryons in galaxies, which has revealed that current models suggest galaxies may be lacking 70-95% of their expected baryonic material. His research team investigates the locations of this missing material, particularly in the hot gas halos surrounding galaxies. His innovative approaches have utilized various techniques to measure these hard-to-detect halos, offering significant insights into the formation and evolution of galaxies. Additionally, Bregman has contributed to notable theories regarding galaxy formations, proposing models to explain how normal matter was led into galaxies and its implications for the universe. He holds a Bachelor of Science from SUNY/Stony Brook and a Ph.D. from UC/Santa Cruz. He has previously served as an Assistant Professor at New York University and held postdoctoral positions at Columbia University. His background includes a significant appointment as a scientist at the National Radio Astronomy Observatory. Bregman's work continues to influence the field and guide astronomers in understanding the complexities of the cosmos.
