Lyman Alpha Galaxies in the Epoch of Reionization

Speaker:Junxian Wang (USTC)

Venue:Video Conference

Time:15:00 PM, Thursday, Jun. 4, 2020

Abstract:

Young galaxies in the early universe are expected to be strong Lyα emitters (LAEs), and can be selected with high efficiency via narrowband imaging. The neutral hydrogen atoms in the IGM scatter/attenuate the Lyα emission from primordial galaxies, making LAEs a sensitive probe to cosmic reionization. I will give an introduction to the field, briefly review world-wide progresses, and present the project “Lyman Alpha Galaxies in the Epoch of Reionization” (LAGER), an international collaboration in searching for LAEs at redshift of ~ 7.0 with large area Dark Energy Camera narrowband survey.
