The X-ray luminosity-temperature relation of a complete sample of low-mass galaxy clusters
Siwei Zou, B. J. Maughan, P. A. Giles +4
We present \Chandra\ observations of 23 galaxy groups and low-mass galaxy clusters at with a median temperature of ~2keV. The sample is a statistically complete flux-…
Testing for X-ray-SZ Differences and Redshift Evolution in the X-ray Morphology of Galaxy Clusters
D. Nurgaliev, M. McDonald, B. A. Benson +12
We present a quantitative study of the X-ray morphology of galaxy clusters, as a function of their detection method and redshift. We analyze two separate samples of galaxy clusters…
Arithmetic with X-ray images of galaxy clusters: effective equation of state for small-scale perturbations in the ICM
E. Churazov, P. Arevalo, W. Forman +4
We discuss a novel technique of manipulating X-ray images of galaxy clusters to reveal the nature of small-scale density/temperature perturbations in the intra cluster medium (ICM)…
Frontier Fields Clusters: Deep Chandra Observations of the Complex Merger MACS J1149.6+2223
G. A. Ogrean, R. J. van Weeren, C. Jones +24
The HST Frontier Fields cluster MACS J1149.6+2223 is one of the most complex merging clusters, believed to consist of four dark matter halos. We present results from deep (365 ks)…
