Thermodynamic Profiles of Galaxy Clusters from a Joint X-ray/SZ Analysis
Jennifer A. Shitanishi, Elena Pierpaoli, Jack Sayers +6
We jointly analyze Bolocam Sunyaev-Zeldovich (SZ) effect and Chandra X-ray data for a set of 45 clusters to derive gas density and temperature profiles without using spectroscopic…
Gas perturbations in cool cores of galaxy clusters: effective equation of state, velocity power spectra and turbulent heating
I. Zhuravleva, S. W. Allen, A. B. Mantz +1
We present the statistical analysis of X-ray surface brightness and gas density fluctuations in cool cores of ten, nearby and bright galaxy clusters that have deep Chandra observat…
A uniform metallicity in the outskirts of massive, nearby galaxy clusters
O. Urban, N. Werner, S. W. Allen +2
Suzaku measurements of a homogeneous metal distribution of Solar in the outskirts of the nearby Perseus cluster suggest that chemical elements were deposited and mixed i…
The Metallicity of the Intracluster Medium Over Cosmic Time: Further Evidence for Early Enrichment
Adam B. Mantz, Steven W. Allen, R. Glenn Morris +4
We use Chandra X-ray data to measure the metallicity of the intracluster medium (ICM) in 245 massive galaxy clusters selected from X-ray and Sunyaev-Zel'dovich (SZ) effect surveys,…
Center-Excised X-ray Luminosity as an Efficient Mass Proxy for Future Galaxy Cluster Surveys
Adam B. Mantz, Steven W. Allen, R. Glenn Morris +1
The cosmological constraining power of modern galaxy cluster catalogs can be improved by obtaining low-scatter mass proxy measurements for even a small fraction of sources. In the…
Witnessing the Growth of the Nearest Galaxy Cluster: Thermodynamics of the Virgo Cluster Outskirts
A. Simionescu, N. Werner, A. Mantz +2
We present results from Suzaku Key Project observations of the Virgo Cluster, the nearest galaxy cluster to us, mapping its X-ray properties along four long `arms' extending beyond…
