Astronomy Colloquium for 2017-09-20

Series: Astronomy Colloquium
Date: Wednesday 20-Sep-2017
Time: 16:05-17:00 (4:05-5:00 pm)
Location: ATL 2400
Speaker: Dr. James Rhoads (GSFC)
Title: "Lyman Alpha Galaxies in the Epoch of Reionization"

Lyman alpha emission from galaxies affords powerful tests of cosmological reionization, because Lyman alpha photons are resonantly scattered by neutral hydrogen. This leads to several possible ways of using Lyman alpha line ongoing surveys sensitive to Lyman alpha in the epoch of reionization, including LAGER (Lyman Alpha Galaxies in the Epoch of Reionization), DAWN (the Deep And Wide Narrowband survey), and FIGS (the Faint Infrared Grism Survey). I will close by discussing prospects for studying reionization history using JWST and WFIRST.

Colloquia are usually preceded by espresso and ice cream at 1:45 pm outside room PSC 1150 and are followed by an informal reception at 5:15 pm in that room. Anyone interested in talking with the speaker, or being added to the colloquium announcement email list, should contact the colloquium organizer. Lunch will normally be reserved for the speaker to talk to graduate students.

Colloquium Organizer: Prof. L. Drake Deming
