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…
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…
Searching for mid-IR obscured AGN in the CDF-N
I. Georgantopoulos, A. Georgakakis, M. Rowan-Robinson +1
The efficiency of mid-infrared selection methods for finding obscured AGN is investigated using data in the \chandra Deep Field North. It is shown that samples of AGN candidates co…
The Phoenix Deep Survey: Extremely Red Galaxies and Cluster Candidates
Anthony G. Smith, Andrew M. Hopkins, Richard W. Hunstead +6
We present the results of a study of a sample of 375 Extremely Red Galaxies (ERGs) in the Phoenix Deep Survey, 273 of which constitute a subsample which is 80% complete to K_s = 18…
