A shock near the virial radius of the Perseus Cluster
Zhenlin Zhu, Aurora Simionescu, Hiroki Akamatsu +6
Previous X-ray studies of the Perseus Cluster, consisting of 85 Suzaku pointings along eight azimuthal directions, revealed a particularly steep decrease in the projected temperatu…
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,…
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…
Suzaku observations of a shock front tracing the western edge of the giant radio halo in the Coma Cluster
Y. Uchida, A. Simionescu, T. Takahashi +5
We present the results of new Suzaku observations of the Coma Cluster, the X-ray brightest, nearby, merging system hosting a well studied, typical giant radio halo. It has been pre…
A Uniform Contribution of Core-Collapse and Type Ia Supernovae to the Chemical Enrichment Pattern in the Outskirts of the Virgo Cluster
A. Simionescu, N. Werner, O. Urban +3
We present the first measurements of the abundances of -elements (Mg, Si, and S) extending out to beyond the virial radius of a cluster of galaxies. Our results, based on Suzaku…
A Suzaku Search for Dark Matter Emission Lines in the X-ray Brightest Galaxy Clusters
O. Urban, N. Werner, S. W. Allen +3
We present the results of a search for unidentified emission lines in deep Suzaku X-ray spectra for the central regions of the four X-ray brightest galaxy clusters: Perseus, Coma,…
A uniform metal distribution in the intergalactic medium of the Perseus cluster of galaxies
Norbert Werner, Ondrej Urban, Aurora Simionescu +1
Most of the metals (elements heavier than helium) ever produced by stars in the member galaxies of galaxy clusters currently reside within the hot, X-ray emitting intra-cluster gas…
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…
Thermodynamics of the Coma Cluster Outskirts
A. Simionescu, N. Werner, O. Urban +10
We present results from a large mosaic of Suzaku observations of the Coma Cluster, the nearest and X-ray brightest hot, dynamically active, non-cool core system, focusing on the th…
Large-scale Motions in the Perseus Galaxy Cluster
A. Simionescu, N. Werner, O. Urban +6
By combining large-scale mosaics of ROSAT PSPC, XMM-Newton, and Suzaku X-ray observations, we present evidence for large-scale motions in the intracluster medium of the nearby, X-r…
X-ray Spectroscopy of the Virgo Cluster out to the Virial Radius
O. Urban, N. Werner, A. Simionescu +2
We present results from the analysis of a mosaic of thirteen XMM-Newton pointings covering the Virgo Cluster from its center northwards out to a radius r~1.2 Mpc (~4.5 degrees), re…
