An Observed Link between Active Galactic Nuclei and Violent Disk Instabilities in High-Redshift Galaxies
Frederic Bournaud, Stephanie Juneau, Emeric Le Floc'h +7
We provide evidence for a correlation between the presence of giant clumps and the occurrence of active galactic nuclei (AGN) in disk galaxies. Giant clumps of 10^8-9 Msun arise fr…
CANDELS: Constraining the AGN-Merger Connection with Host Morphologies at z~2
Dale D. Kocevski, S. M. Faber, Mark Mozena +35
Using HST/WFC3 imaging taken as part of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS), we examine the role that major galaxy mergers play in triggeri…
Testing the global star formation relation: An HCO+ (3-2) mapping study of Red MSX sources in the Bolocam Galactic Plane Survey
David E. Schenck, Yancy L. Shirley, Megan Reiter +1
We present an analysis of the relation between the star formation rate (SFR) and mass of dense gas in Galactic clumps and nearby galaxies. Using the bolometric luminosity as a meas…
Observational constraints on the physics behind the evolution of AGN since z ~ 1
A. Georgakakis, A. L. Coil, C. N. A. Willmer +7
We explore the evolution with redshift of the rest-frame colours and space densities of AGN hosts (relative to normal galaxies) to shed light on the dominant mechanism that trigger…
Red Nuggets at High Redshift: Structural Evolution of Quiescent Galaxies Over 10 Gyr of Cosmic History
Ivana Damjanov, Roberto G. Abraham, Karl Glazebrook +15
We present an analysis of the size growth seen in early-type galaxies over 10 Gyr of cosmic time. Our analysis is based on a homogeneous synthesis of published data from 17 spectro…
A CANDELS WFC3 Grism Study of Emission-Line Galaxies at z~2: A Mix of Nuclear Activity and Low-Metallicity Star Formation
Jonathan R. Trump, Benjamin J. Weiner, Claudia Scarlata +26
We present Hubble Space Telescope Wide Field Camera 3 slitless grism spectroscopy of 28 emission-line galaxies at z~2, in the GOODS-S region of the Cosmic Assembly Near-infrared De…
