A census of AGN-driven ionized outflows at the cosmic high noon with the MOSDEF survey

Friday, November 8, 2019 - 12:15pm to 1:00pm
Gene Leung (UCSD)

Using data from the MOSDEF survey, we present a census of AGN-driven ionized outflows in a sample of 159 AGNs at 1.4 < z < 3.8, the largest such sample at z ~ 2. We detect outflows in 17% of the AGNs, seven times more often than in a mass-matched sample of inactive galaxies in MOSDEF.

Galactic Archeology of the Brightest Cluster Galaxy M87

Friday, October 18, 2019 - 12:15pm to 1:00pm
Alexa Villaume (UCSC)

The galactocentric radial metallicity gradients of GC systems can be used to probe the assembly histories of galaxies but doing so is complicated by: 1.) a GC system is an aggregate population of several (or many) different subpopulations of different origins, and 2.) computing the gradients with

Deciphering the Evolution of Galaxy Kinematics and Clustering Behaviour over Cosmic Time using Observed Lyman-α Relationships

Friday, May 31, 2019 - 12:15pm to 1:00pm
Garry Foran (Swinburne)

Lyman-α (Lyα) is the strongest, and sometimes the only, spectral feature of high
redshift galaxies. Due to the complex radiative transport mechanism by which it
escapes, the Lyα radiation observed from a given galaxy encodes information about
