Lyman alpha Galaxies at the Epoch of Reionzation (LAGER)
This is a multinational collaboration to survey 20+ square degrees in narrow band filters to finc lyman-alpha galaxies at redshift of 7. The aim of this project is to determine the neutral fraction of inter-galactic medium at the epoch of reionization.
Green Peas as local analogs of Lyman-alpha galaxies
Green Pea galaxies are nearby galaxies with extremely strong emission lines in their optical spectra. They were named by citizen scientist volunteers in the Galaxy Zoo project, because they appear small, round, and green in color-composite Sloan Digital Sky Survey images. Their unusual color is because the optical emission lines are strong enough to dominate over starlight in their colors.
Our research has shown that green peas are good nearby analogs of high redshift Lyman alpha galaxies. Their relative proximity allows detailed study of many properties that cannot be studied well at the distances of high-redshift Lyman alpha Green Pea galaxies are nearby galaxies with extremely strong emission lines in their optical spectra. These include detailed studies of Lyman alpha line profiles, chemical abundances, and gas content.
Cosmic Dawn studies with WFIRST
WFIRST has the potential to make groundbreaking contributions in the study of Cosmic Dawn. We are making detailed investigations and simulations of WFIRST observations to find high redshift gaklaxies and quasars in the first billion light years of the universe. This is in collaboration with an international team.
