Substructure and Scatter in the Mass-Temperature Relations of Simulated Clusters
David A. Ventimiglia, G. Mark Voit, Megan Donahue +1
Galaxy clusters exhibit regular scaling relations among their bulk properties. These relations establish vital links between halo mass and cluster observables. Precision cosmology…
An Entropy Threshold for Strong H-alpha and Radio Emission in the Cores of Galaxy Clusters
Kenneth W. Cavagnolo, Megan Donahue, G. Mark Voit +1
Our Chandra X-ray Observatory archival study of intracluster entropy in a sample of 222 galaxy clusters shows that H-alpha and radio emission from the brightest cluster galaxy are…
An Infrared Survey of Brightest Cluster Galaxies. II: Why are Some Brightest Cluster Galaxies Forming Stars?
Christopher P. O'Dea, Stefi A. Baum, George Privon +12
Quillen et al.(2007) presented an imaging survey with the {\it Spitzer Space Telescope} of 62 brightest cluster galaxies with optical line emission located in the cores of X-ray lu…
Infrared Emission from the Nearby Cool Core Cluster Abell 2597
Megan Donahue, Andres Jordan, Stefi A. Baum +9
We observed the brightest central galaxy (BCG) in the nearby (z=0.0821) cool core galaxy cluster Abell 2597 with the IRAC and MIPS instruments on board the Spitzer Space Telescope.…
Star Formation, Radio Sources, Cooling X-ray Gas, and Galaxy Interactions in the Brightest Cluster Galaxy in 2A0335+096
Megan Donahue, Ming Sun, Christopher P. O'Dea +2
We present deep emission-line imaging taken with the SOAR Optical Imaging Camera of the brightest cluster galaxy (BCG) in the nearby (z=0.035) X-ray cluster 2A0335+096. We analyze…
The Representative XMM-Newton Cluster Structure Survey (REXCESS) of an X-ray Luminosity Selected Galaxy Cluster Sample
H. Boehringer, P. Schuecker, G. W. Pratt +31
The largest uncertainty for cosmological studies using clusters of galaxies is introduced by our limited knowledge of the statistics of galaxy cluster structure, and of the scaling…
