A unified empirical model for infrared galaxy counts based on observed physical evolution of distant galaxies

Matthieu Béthermin, Emanuele Daddi, Georgios Magdis +10

We reproduce the mid-infrared to radio galaxy counts with a new empirical model based on our current understanding of the evolution of main-sequence (MS) and starburst (SB) galaxie…

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…

The hidden side of cosmic star formation at z > 3: Bridging optically-dark and Lyman break galaxies with GOODS-ALMA

Mengyuan Xiao, David Elbaz, Carlos Gómez-Guijarro +37

Our current understanding of the cosmic star formation history at z>3 is primarily based on UV-selected galaxies (i.e., LBGs). Recent studies of H-dropouts have revealed that we ma…

GOODS-Herschel: Impact of Active Galactic Nuclei and Star Formation Activity on Infrared Spectral Energy Distributions at High Redshift

Allison Kirkpatrick, Alexandra Pope, David M. Alexander +25

We explore the effects of active galactic nuclei (AGN) and star formation activity on the infrared (0.3-1000 microns) spectral energy distributions of luminous infrared galaxies fr…

Searching for Compton-thick active galactic nuclei at z~0.1

Andy Goulding, David Alexander, James Mullaney +4

Using a suite of X-ray, mid-IR and optical active galactic nuclei (AGN) luminosity indicators, we search for Compton-thick (CT) AGNs with intrinsic L_X>10^42erg/s at z~0.03-0.2, a…

The Quasar Feedback Survey: zooming into the origin of radio emission with e-MERLIN

Ann Njeri, Chris M. Harrison, Preeti Kharb +7

We present 6 GHz e-MERLIN observations of 42 type 1 and type 2 mostly radio-quiet quasars ( erg s; erg s$^{-…
