Powerful yet lonely: Is 3C 297 a high-redshift fossil group?

Valentina Missaglia, Juan P. Madrid, Mischa Schirmer +8

The environment of the high-redshift (z=1.408), powerful radio-loud galaxy 3C 297 has several distinctive features of a galaxy cluster. Among them, a characteristic halo of hot gas…

The cavity of 3CR 196.1: H emission spatially associated with an X-ray cavity

A. Jimenez-Gallardo, E. Sani, F. Ricci +20

We present a multifrequency analysis of the radio galaxy 3CR 196.1 (), associated with the brightest galaxy of the cool core cluster CIZAJ0815.4-0303. This nearby radio…

The X-ray Polarization View of Mrk~421 in an Average Flux State as Observed by the Imaging X-ray Polarimetry Explorer

Laura Di Gesu, Immacolata Donnarumma, Fabrizio Tavecchio +100

Particle acceleration mechanisms in supermassive black hole jets, such as shock acceleration, magnetic reconnection, and turbulence, are expected to have observable signatures in t…

Jet-ISM interaction in NGC 1167 / B2 0258+35, A LINER with an AGN past

G. Fabbiano, A. Paggi, R. Morganti +9

We report the results of joint Chandra/ACIS - NuSTAR deep observations of NGC 1167, the host galaxy of the young radio jet B2 0258+35. In the ACIS data we detect X-ray emission, ex…

Polarized Blazar X-rays imply particle acceleration in shocks

Ioannis Liodakis, Alan P. Marscher, Iván Agudo +125

Most of the light from blazars, active galactic nuclei with jets of magnetized plasma that point nearly along the line of sight, is produced by high-energy particles, up to $\sim 1…

A multifrequency characterization of the extragalactic hard X-ray sky

Matej Kosiba, Harold Andres Peña-Herazo, Francesco Massaro +5

Nowadays we know that the origin of the Cosmic X-ray Background (CXB) is due to the integrated emission of nearby active galactic nuclei. Thus, to obtain a precise estimate of the…
