Evolution of the Intracluster Medium Between 0.2 < z < 1.3 in a Chandra Sample of 70 Galaxy Clusters
T. B. O'Hara, J. J. Mohr, A. J. R. Sanderson
We study the evolution of the ICM with a sample of 70 galaxy clusters spanning 0.18 < z < 1.24. We find that X-ray luminosity and ICM mass at a fixed temperature evolve with redshi…
Bayesian modelling of the cool core galaxy group NGC 4325
Paul A. Russell, Trevor J. Ponman, Alastair J. R. Sanderson
We present an X-ray analysis of the radio-quiet cool-core galaxy group NGC 4325 (z=0.026) based on Chandra and ROSAT observations. The Chandra data were analysed using XSPEC deproj…
Missing Thermal Energy of the Intracluster Medium
Niayesh Afshordi, Yen-Ting Lin, Daisuke Nagai +1
The Sunyaev-Zel'dovich (SZ) effect is a direct probe of thermal energy content of the Universe, induced in the cosmic microwave background (CMB) sky through scattering of CMB photo…
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…
The X-ray Scaling Properties of Virialized Systems
Alastair J. R. Sanderson, Trevor J. Ponman
Virialized systems, such as clusters and groups of galaxies, represent an ideal laboratory for investigating the formation and evolution of structure on the largest scales. Further…
