Lighting Up the Gas Reservoir Outside Galaxies

Friday October 5, 2018
3:30 pm


 Presenter:  Moire Prescott, NMSU
 Series:  Physics and Astronomy Colloquium
 Abstract:  The diffuse gas reservoir outside of galaxies holds important clues to the galaxy formation process. Circumgalactic gas fuels the formation of new generations of stars within individual galaxies and the growth of active galactic nuclei (AGN), while at the same time feeling the effects star formation and AGN feedback, as enriched material is expelled back out of galaxies and into the surrounding environment. Lyman-alpha nebulae — giant emission-line nebulae found at the nodes of this web of cosmic gas — allow us to study the circumgalactic medium in emission and provide a window into the early stages of galaxy group and cluster formation. This talk will discuss the progress we have made characterizing the environments of and powering mechanisms at work in giant Lyman-alpha nebulae, and highlight what we are learning from mapping out the physical conditions and kinematics within individual regions and across cosmic time.
 Host:  Ylva Pihlström
 Location:  Room 125, Dane Smith Hall
 

Refreshments will be available before the colloquium, at 03:15 pm, in in the lobby of Dane Smith Hall.
