Cosmological Constraints from Gas Mass Fractions of Massive, Relaxed Galaxy Clusters
Adam B. Mantz, Steven W. Allen, Rebecca E. A. Canning +14
We present updated cosmological constraints from measurements of the gas mass fractions () of massive, dynamically relaxed galaxy clusters. Our new data set has greater le…
X-ray Bright Active Galactic Nuclei in Massive Galaxy Clusters II: The Fraction of Galaxies Hosting Active Nuclei
S. Ehlert, A. von der Linden, S. W. Allen +7
We present a measurement of the fraction of cluster galaxies hosting X-ray bright Active Galactic Nuclei (AGN) as a function of clustercentric distance scaled in units of …
Azimuthally Resolved X-Ray Spectroscopy to the Edge of the Perseus Cluster
O. Urban, A. Simionescu, N. Werner +9
We present the results from extensive, new observations of the Perseus Cluster of galaxies, obtained as a Suzaku Key Project. The 85 pointings analyzed span eight azimuthal directi…
Probing the extreme realm of AGN feedback in the massive galaxy cluster, RX J1532.9+3021
J. Hlavacek-Larrondo, S. W. Allen, G. B. Taylor +7
We present a detailed Chandra, XMM-Newton, VLA and HST analysis of one of the strongest cool core clusters known, RX J1532.9+3021 (z=0.3613). Using new, deep 90 ks Chandra observat…
Ripping Apart at the Seams: The Network of Stripped Gas Surrounding M86
S. Ehlert, N. Werner, A. Simionescu +4
We present a new study of the Virgo Cluster galaxies M86, M84, NGC 4338, and NGC 4438 using a mosaic of five separate pointings with XMM-Newton. Our observations allow for robust m…
X-ray Bright Active Galactic Nuclei in Massive Galaxy Clusters I: Number Counts and Spatial Distribution
S. Ehlert, S. W. Allen, W. N. Brandt +5
We present an analysis of the X-ray bright point source population in 43 massive clusters of galaxies observed with the Chandra X-ray Observatory. We have constructed a catalog of…
