SMBH Seeds: Model Discrimination with High Energy Emission Based on Scaling Relation Evolution
Sagi Ben-Ami, Alexey Vikhlinin, Abraham Loeb
We explore the expected X-ray (0.5-2keV) signatures from super massive black holes (SMBHs) at high redshifts () assuming various models for their seeding mechanism and e…
Recovering galaxy cluster gas density profiles with XMM-Newton and Chandra
I. Bartalucci, M. Arnaud, G. W. Pratt +6
We examine the reconstruction of galaxy cluster radial density profiles obtained from Chandra and XMM X-ray observations, using high quality data for a sample of twelve objects cov…
Pressure profiles of distant galaxy clusters in the Planck catalog
H. Bourdin, P. Mazzotta, A. Kozmanyan +2
Successive releases of Planck data have demonstrated the strength of the Sunyaev--Zeldovich (SZ) effect in detecting hot baryons out to the galaxy cluster peripheries. To infer the…
Partitioning the Outburst Energy of a Low Eddington Accretion Rate AGN at the Center of an Elliptical Galaxy: the Recent 12 Myr History of the Supermassive Black Hole in M87
W. Forman, E. Churazov, C. Jones +3
M87, the active galaxy at the center of the Virgo cluster, is ideal for studying the interaction of a supermassive black hole (SMBH) with a hot, gas-rich environment. A deep Chandr…
The fraction of cool-core clusters in X-ray vs. SZ samples using Chandra observations
Felipe Andrade-Santos, Christine Jones, William R. Forman +21
We derive and compare the fractions of cool-core clusters in the {\em Planck} Early Sunyaev-Zel'dovich sample of 164 clusters with and in a flux-limited X-ray sample…
