Cosmological constraints from evolution of cluster baryon mass function at z~0.5
A. Vikhlinin, A. Voevodkin, C. R. Mullis +8
We present a new method for deriving cosmological constraints based on the evolution of the baryon mass function of galaxy clusters, and implement it using 17 distant clusters from…
Chandra Spectra of the Soft X-ray Diffuse Background
M. Markevitch, M. W. Bautz, B. Biller +14
We present an exploratory Chandra ACIS-S3 study of the diffuse component of the Cosmic X-ray Background in the 0.3-7 keV band for four directions at high Galactic latitudes, with e…
A Cold Front in A3667: Hydrodynamics and Magnetic Field in the Intracluster Medium
A. Vikhlinin, M. Markevitch
This conference presentation discusses a Chandra observation of the cold front in Abell 3667. We first review our earlier results which include a measurement of the front velocity,…
The Flight Spectral Response of the ACIS Instrument
Paul P. Plucinsky, Norbert S. Schulz, Herman L. Marshall +11
We discuss the flight calibration of the spectral response of the Advanced CCD Imaging Spectrometer (ACIS) on-board the Chandra X-ray Observatory (CXO). The spectral resolution and…
A High Resolution Picture of the Intracluster Gas
M. Markevitch, A. Vikhlinin, W. R. Forman
Chandra has significantly advanced our knowledge of the processes in the intracluster gas. The discovery of remarkably regular ``cold fronts'', or contact discontinuities, in mergi…
Galaxy Clusters with Chandra
W. Forman, C. Jones, M. Markevitch +2
We discuss Chandra results related to 1) cluster mergers and cold fronts and 2) interactions between relativistic plasma and hot cluster atmospheres. We describe the properties of…
