Group connectivity in COSMOS: a tracer of mass assembly history
E. Darragh-Ford, C. Laigle, G. Gozaliasl +11
Cosmic filaments are the channel through which galaxy groups assemble their mass. Cosmic connectivity, namely the number of filaments connected to a given group, is therefore expec…
Suzaku Observation of Two Ultraluminous X-Ray Sources in NGC 1313
T. Mizuno, R. Miyawaki, K. Ebisawa +19
Two ultraluminous X-ray sources (ULXs) in the nearby Sb galaxy NGC 1313, named X-1 and X-2, were observed with Suzaku on 2005 September 15. During the observation for a net exposur…
An X-ray Galaxy Cluster Survey for Investigations of Dark Energy
Z. Haiman, S. Allen, N. Bahcall +34
The amount and nature of dark energy (DE) can be tightly constrained by measuring the spatial correlation features and evolution of a sample of ~ 100,000 galaxy clusters over the r…
ASCA observations of Deep ROSAT fields - III. The Discovery of an Obscured Type 2 AGN at z=0.67
B. J. Boyle, O. Almaini, I. Georgantopoulos +5
We report on the discovery of a narrow-emission-line object at z=0.672 detected in a deep ASCA survey. The object, AXJ0341.4-4453, has a flux in the 2--10keV band of 1.1+/-0.27 E-1…
ASCA observations of Deep ROSAT fields - II. The 2-10keV AGN luminosity function
B. J. Boyle, I. Georgantopoulos, A. J. Blair +5
We present additional optical spectroscopic identifications of sources identified in three deep ASCA GIS fields which also form part of a deep ROSAT survey. In total, 26 ASCA sourc…
A deep ROSAT survey - IV. The evolution of X-ray-selected QSOs
B. J. Boyle, T. Shanks, I. Georgantopoulos +2
We report on a new estimate of the QSO X-ray luminosity function and its evolution with redshift based on a sample of 107 QSOs detected at faint X-ray fluxes, $S{\rm(0.5-2\,keV)}>4…
