A Swift X-ray view of the SMS4 sample -- X-ray properties of 31 quasars and radio galaxies

Alessandro Maselli, William R. Forman, Christine Jones +2

We present Swift observations of 31 sources from the SMS4 catalog, a sample of 137 bright radio sources in the Southern Hemisphere. All these sources had no Chandra or XMM-Newton o…

The Chandra Deep Wide-Field Survey: A New Chandra Legacy Survey in the Boötes Field I. X-ray Point Source Catalog, Number Counts and Multi-Wavelength Counterparts

A. Masini, R. C. Hickox, C. M. Carroll +30

We present a new, ambitious survey performed with the Chandra X-ray Observatory of the 9.3 deg Boötes field of the NOAO Deep Wide-Field Survey. The wide field probes a statisti…

The discovery of radio halos in the Frontier Fields clusters Abell S1063 and Abell 370

C. Xie, R. J. van Weeren, L. Lovisari +13

Massive merging galaxy clusters often host diffuse Mpc-scale radio synchrotron emission. This emission originates from relativistic electrons in the ionized intracluster medium (IC…

Detection of Superluminal Motion in the X-Ray Jet of M87

Bradford Snios, Paul E. J. Nulsen, Ralph P. Kraft +5

Chandra HRC observations are investigated for evidence of proper motion and brightness changes in the X-ray jet of the nearby radio galaxy M87. Using images spanning 5 yr, proper m…
