Probing the Outskirts of the Early Stage Galaxy Cluster Merger A1750
Esra Bulbul, Scott W. Randall, Matthew Bayliss +12
We present results from recent Suzaku and Chandra X-ray, and MMT optical observations of the strongly merging "double cluster" A1750 out to its virial radius, both along and perpen…
X-ray emissivity of old stellar populations: a local group census
Chong Ge, Zhiyuan Li, Xiaojie Xu +6
We study the unresolved X-ray emission in three Local Group dwarf elliptical galaxies (NGC 147, NGC 185 and NGC 205) using XMM-Newton observations, which most likely originates fro…
Chandra and XMM-Newton observations of the merging cluster of galaxies PLCK G036.7+14.9
B. Zhang, L. P. David, C. Jones +13
We present Chandra and XMM-Newton observations of PLCK G036.7+14.9 from the Chandra-Planck Legacy Program. The high resolution X-ray observations reveal two close subclusters, G036…
Hot Gaseous Coronae around Spiral Galaxies: Probing the Illustris Simulation
Akos Bogdan, Mark Vogelsberger, Ralph P. Kraft +10
The presence of hot gaseous coronae around present-day massive spiral galaxies is a fundamental prediction of galaxy formation models. However, our observational knowledge remains…
Chandra and XMM-Newton Observations of the Bimodal Planck SZ-detected Cluster PLCKG345.40-39.34 (A3716) with High and Low Entropy Subcluster Cores
Felipe Andrade-Santos, Christine Jones, William R. Forman +11
We present results from Chandra, XMM-Newton, and ROSAT observations of the Planck SZ-detected cluster A3716 (PLCKG345.40-39.34 - G345). We show that G345 is, in fact, two subcluste…
A Connection between Obscuration and Star Formation in Luminous Quasars
Chien-Ting J. Chen, Ryan C. Hickox, Stacey Alberts +15
We present a measurement of the star formation properties of a uniform sample of mid-IR selected, unobscured and obscured quasars (QSO1s and QSO2s) in the Boötes survey region. We…
