Are red 2MASS QSOs young?
A. Georgakakis, D. L. Clements, G. Bendo +3
We use photometric data from Spitzer to explore the mid- and far-IR properties of 10 red QSOs (J-K>2, R-K>5) selected by combining the 2MASS in the NIR with the SDSS at optical wav…
AEGIS-X: The Chandra Deep Survey of the Extended Groth Strip
E. S. Laird, K. Nandra, A. Georgakakis +11
We present the AEGIS-X survey, a series of deep Chandra ACIS-I observations of the Extended Groth Strip. The survey comprises pointings at 8 separate positions, each with nominal e…
On the nature of unabsorbed Seyfert 2 galaxies
Murray Brightman, Kirpal Nandra
We present an analysis of six 12 um selected Seyfert 2 galaxies that have been reported to be unabsorbed in the X-ray. By comparing the luminosities of these galaxies in the mid-IR…
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…
