The Curious Case of Lyman-alpha Emitting Galaxies
Presented by Zheng Zheng
Department of Physics and Astronomy, University of Utah

Thursday, April 26, 2018
11:00 A.M. in 169-336

Abstract
Lyman-alpha Emitting galaxies or Lyman-alpha emitters (LAEs), star-forming galaxies selected through their strong Lyman-alpha emission, are becoming an important probe of galaxy formation, cosmic reionization, and cosmology. I will present our recent and ongoing work towards understanding properties of those galaxies based on Lyman-alpha radiative transfer modeling, discussing the role of the anisotropic gas distribution around galaxies and the origin of the extended Lyman-alpha emission around LAEs. I will then talk about the anisotropic clustering of LAEs induced by the radiative transfer effect and the current observational status. During the talk, I will also discuss a few puzzles in the study of LAEs.
