Chandra Cluster Cosmology Project III: Cosmological Parameter Constraints
A. Vikhlinin, A. V. Kravtsov, R. A. Burenin +8
Chandra observations of large samples of galaxy clusters detected in X-rays by ROSAT provide a new, robust determination of the cluster mass functions at low and high redshifts. St…
Chandra's View of the Ram Pressure Stripped Galaxy M86
S. Randall, P. Nulsen, W. R. Forman +4
We present results from a mosaic of nine Chandra observations of M86 and the surrounding field. We detect three main diffuse components: the Virgo ICM at ~2.4 keV, the extended hal…
Chandra studies of the X-ray gas properties of galaxy groups
M. Sun, G. M. Voit, M. Donahue +3
We present a systematic analysis of 43 galaxy groups (kT_500=0.7-2.7 keV or M_500=10^13-10^14 h^-1 M_solar, 0.012<z<0.12), based on Chandra archival data. With robust background su…
Chandra Cluster Cosmology Project II: Samples and X-ray Data Reduction
A. Vikhlinin, R. A. Burenin, H. Ebeling +8
We discuss the measurements of the galaxy cluster mass functions at z=~0.05 and z=~0.5 using high-quality Chandra observations of samples derived from the ROSAT PSPC All-Sky and 40…
Evidence for Non-Hydrostatic Gas Motions in the Hot ISM of Centaurus A
R. P. Kraft, M. J. Hardcastle, G. R. Sivakoff +16
We present preliminary results from a deep (600 ks) {\em Chandra} observation of the hot interstellar medium of the nearby early-type galaxy Centaurus A (Cen A). We find a surface…
Globular Clusters and X-ray Point Sources in Centaurus A (NGC 5128)
Kristin A. Woodley, Somak Raychaudhury, Ralph P. Kraft +6
We detect 353 X-ray point sources, mostly low-mass X-ray binaries (LMXBs), in four Chandra observations of Centaurus A (NGC 5128), the nearest giant early-type galaxy, and correlat…
