Biography and Research Information
OverviewAI-generated summary
Bret Lehmer's research focuses on the study of active galactic nuclei and the evolution of X-ray emission from galaxies across cosmic history. His work has involved analyzing large astronomical survey data, including extensive observations from the Chandra Deep Field-South. Lehmer has published on source catalogs from these surveys, investigating the properties of active galaxies, and examining the correlation between X-ray binary emission, star formation rates, and stellar mass in luminous infrared galaxies.
His research also explores energy feedback mechanisms from X-ray binaries in the early universe and constrains the evolution of normal galaxy X-ray emission through cosmic time. Lehmer has co-authored publications with collaborators Zachary Wilson, Emerson Gehr, and Izabela Pavel, all from the University of Arkansas at Fayetteville. His h-index is 1, with 33 total publications and 78 citations.
