The discovery of lensed radio and X-ray sources behind the Frontier Fields cluster MACS J0717.5+3745 with the JVLA and Chandra
R. J. van Weeren, G. A. Ogrean, C. Jones +24
We report on high-resolution JVLA and Chandra observations of the HST Frontier Cluster MACS J0717.5+3745. MACS J0717.5+3745 offers the largest contiguous magnified area of any know…
Beyond Chandra - the X-ray Surveyor
Martin C. Weisskopf, Jessica Gaskin, Harvey Tananbaum +1
Over the past 16 years, NASA's Chandra X-ray Observatory has provided an unparalleled means for exploring the universe with its half-arcsecond angular resolution. Chandra studies h…
(No) dimming of X-ray clusters beyond z~1 at fixed mass: crude redhshifts and masses from raw X-ray and SZ data
E. Churazov, A. Vikhlinin, R. Sunyaev
Scaling relations in the LCDM Cosmology predict that for a given mass the clusters formed at larger redshift are hotter, denser and therefore more luminous in X-rays than their loc…
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…
