Intracluster Medium Entropy Profiles for a Chandra Archival Sample of Galaxy Clusters
Kenneth W. Cavagnolo, Megan Donahue, G. Mark Voit +1
We present radial entropy profiles of the intracluster medium (ICM) for a collection of 239 clusters taken from the Chandra X-ray Observatory's Data Archive. Entropy is of great in…
Conduction and the Star-Formation Threshold in Brightest Cluster Galaxies
G. M. Voit, K. W. Cavagnolo, M. Donahue +3
Current models of galaxy evolution suggest that feedback from active galactic nuclei is needed to explain the high-luminosity cutoff in the galaxy luminosity function. Exactly how…
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…
Bandpass Dependence of X-ray Temperatures in Galaxy Clusters
Kenneth W. Cavagnolo, Megan Donahue, G. Mark Voit +1
We explore the band dependence of the inferred X-ray temperature of the intracluster medium (ICM) for 192 well-observed galaxy clusters selected from the Chandra Data Archive. If t…
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…
Abundances of s-process elements in planetary nebulae: Br, Kr & Xe
Y. Zhang, R. Williams, E. Pellegrini +5
We identify emission lines of post-iron peak elements in very high signal-to-noise spectra of a sample of planetary nebulae. Analysis of lines from ions of Kr and Xe reveals enhanc…
