X-ray selected AGN in groups at redshifts z~1
A. Georgakakis, Brian F. Gerke, K. Nandra +4
We explore the role of the group environment in the evolution of AGN at the redshift interval 0.7<z<1.4, by combining deep Chandra observations with extensive optical spectroscopy…
A new method for determining the sensitivity of X-ray imaging observations and the X-ray number counts
A. Georgakakis, K. Nandra, E. S. Laird +2
We present a new method for determining the sensitivity of X-ray imaging observations, which correctly accounts for the observational biases that affect the probability of detectin…
The X-ray luminosity function of AGN at z~3
James Aird, Kirpal Nandra, Antonis Georgakakis +3
We combine Lyman-break colour selection with ultradeep (> 200 ks) Chandra X-ray imaging over a survey area of ~0.35 deg^2 to select high redshift AGN. Applying careful corrections…
AEGIS: Radio and Mid-Infrared Selection of Obscured AGN Candidates
S. Q. Park, P. Barmby, G. G. Fazio +10
The application of multi-wavelength selection techniques is crucial for discovering a complete and unbiased set of Active Galactic Nuclei (AGNs). Here, we select a sample of 72 AGN…
The role of AGN in the colour transformation of galaxies at redshifts z~1
A. Georgakakis, K. Nandra, R. Yan +10
We explore the role of AGN in establishing and/or maintaining the bimodal colour distribution of galaxies by quenching their star-formation and hence, causing their transition from…
The Environment on few Mpc scales of Infrared Luminous Galaxies at Redshifts z~1
D. Marcillac, G. H. Rieke, C. Papovich +13
We investigate the environment of infrared luminous galaxies (L[8-1000 mL$_{\sun}$). We focus on the redshift range 0.7 z 1, where these galaxie…
