Erratum: "Chandra Sample of Nearby Relaxed Galaxy Clusters: Mass, Gas Fraction, and Mass-Temperature Relation"
We present gas and total mass profiles for 13 low-redshift, relaxed clusters spanning a temperature range 0.7-9 keV, derived from all available Chandra data of sufficient quality. In all clusters,
An overview of the performance and scientific results from the Chandra X-ray Observatory (CXO)
ABSTRACT The Chandra X‐Ray Observatory (CXO), the X‐ray component of NASA’s Great Observatories, was launched on 1999 July 23 by the space shuttle Columbia. After satellite systems activation, the
Chandra Temperature Profiles for a Sample of Nearby Relaxed Galaxy Clusters
We present Chandra gas temperature profiles at large radii for a sample of 13 nearby, relaxed galaxy clusters and groups, which includes A133, A262, A383, A478, A907, A1413, A1795, A1991, A2029,
Images, Structural Properties, and Metal Abundances of Galaxy Clusters Observed with Chandra ACIS-I at 0.1 < z < 1.3
We have assembled a sample of 115 galaxy clusters at 0.1 0.5. The slope of the surface brightness profiles at large radii were steeper on average by 15% than the slope obtained by fitting a simple
A complete sample of 12 very x-ray luminous galaxy clusters at z >0.5
We present the statistically complete and cosmologically most relevant subset of the 12 most distant galaxy clusters detected at z > 0.5 by the Massive Cluster Survey (MACS). Ten of these systems are
Constraints on dark energy from Chandra observations of the largest relaxed galaxy clusters
We present constraints on the mean matter density, {Omega}{sub m}, dark energy density, {Omega}{sub DE}, and the dark energy equation of state parameter, w, using Chandra measurements of the X-ray
The X-ray brightest clusters of galaxies from the Massive Cluster Survey
We present a statistically complete sample of very X-ray luminous galaxy clusters detected in the MAssive Cluster Survey (MACS). This second MACS release comprises all 34 MACS clusters with nominal
The Einstein /HEAO 2/ X-ray Observatory
The Einstein (HEAO 2) X-ray Observatory, launched in 1978, includes a fully imaging focusing X-ray telescope with an angular resolution of a few arc sec, a field of view of up to one deg, and a
Einstein imaging observations of clusters with a bimodal mass distribution
A morphologically distinct class of clusters characterized by a double structure in their X-ray surface brightness distribution has been identified from imaging observations made with the Einstein
Observations of X-ray sources in M31
We have observed 69 unresolved X-ray sources and seven diffuse or confused source regions in M31 with the Einstein Observatory. The typical limiting sensitivies in the 0.5--4.5 keV band were 9 x
