We study the azimuthal scatter in the radial profiles of X-ray luminous galaxy clusters, with two sets of high-resolution cosmological re-simulations obtained with the codes ENZO a…
Wide-field VLBA Observations of the Chandra Deep Field South
Enno Middelberg, Adam Deller, John Morgan +7
Wide-field surveys are a commonly-used method for studying thousands of objects simultaneously, to investigate, e.g., the joint evolution of star-forming galaxies and active galact…
Particle reacceleration by compressible turbulence in galaxy clusters: effects of reduced mean free path
G. Brunetti, A. Lazarian
Direct evidence for in situ particle acceleration mechanisms in the inter-galactic-medium (IGM) is provided by the diffuse Mpc--scale synchrotron emissions observed from galaxy clu…
Dying Radio Sources in Clusters

We present the study of five `dying' nearby radio galaxies belonging to the WENSS minisurvey and to the B2 bright catalogs: WNB1734+6407, WNB1829+6911, WNB1851+5707, B2 0120+33, an…
The Australia Telescope 20GHz (AT20G) Survey: analysis of the extragalactic source sample
Marcella Massardi, Ronald D. Ekers, Tara Murphy +20
The Australia Telescope 20 GHz (AT20G) survey is a blind survey of the whole Southern sky at 20 GHz with follow-up observations at 4.8, 8.6, and 20 GHz carried out with the Austral…
The 1.6 micron near infrared nuclei of 3C radio galaxies: Jets, thermal emission or scattered light?
R. D. Baldi, M. Chiaberge, A. Capetti +6
Using HST NICMOS 2 observations we have measured 1.6-micron near infrared nuclear luminosities of 100 3CR radio galaxies with z<0.3, by modeling and subtracting the extended emissi…

Giulia Macario, Maxim Markevitch, Simona Giacintucci +3
We present new Chandra X-ray and Giant Meterwave Radio Telescope (GMRT) radio observations of the nearby merging galaxy cluster Abell 754. Our X-ray data confirm the presence of a…
The jet in M87 from EVN observations
G. Giovannini, C. Casadio, M. Giroletti +3
One of the most intriguing open questions of today's astrophysics is the jet physical properties and the location and the mechanisms for the production of MeV, GeV, and TeV gamma-r…
An optical spectroscopic survey of the 3CR sample of radio galaxies with z<0.3. III. Completing the sample
Sara Buttiglione, Alessandro Capetti, Annalisa Celotti +4
We present optical nuclear spectra for nine 3CR radio sources obtained with the Telescopio Nazionale Galileo, that complete our spectroscopic observations of the sample up to redsh…
