Cocoon shock, X-ray cavities and extended Inverse Compton emission in Hercules A: clues from Chandra observations
F. Ubertosi, Y. Gong, P. Nulsen +7
We present a detailed analysis of jet activity in the radio galaxy 3C348 at the center of the galaxy cluster Hercules A. We use archival Chandra data to investigate the jet-driven…
Probing the high frequency variability of NGC 5044: the key to AGN feedback
Gerrit Schellenberger, Ewan O'Sullivan, Laurence David +10
The active galactic nucleus (AGN) feeding and feedback process in the centers of galaxy clusters and groups is still not well understood. NGC 5044 is the ideal system in which to s…
The Multi-Epoch Jet Outbursts in Abell 496: synchrotron ageing and buoyant X-ray cavities draped by warm gas filaments
Francesco Ubertosi, Simona Giacintucci, Tracy Clarke +4
The galaxy cluster Abell 496 has been extensively studied in the past for the clear sloshing motion of the hot gas on large scales, but the interplay between the central radio gala…
Mind the Gap between A2061 and A2067: Unveiling new diffuse large-scale radio emission
G. V. Pignataro, A. Bonafede, G. Bernardi +11
The clusters Abell 2061 and Abell 2067 in the Corona Borealis supercluster have been studied at different radio frequencies and are both known to host diffuse radio emission. The a…
From 100 MHz to 10 GHz: Unveiling the spectral evolution of the X-shaped radio galaxy in Abell 3670
L. Bruno, M. Brienza, A. Zanichelli +5
X-shaped radio galaxies (XRGs) are characterised by two pairs of misaligned lobes, namely the active lobes hosting radio jets and the wings. None of the formation mechanisms propos…
A hot core in the group-dominant elliptical galaxy NGC 777
Ewan O'Sullivan, Kamlesh Rajpurohit, Gerrit Schellenberger +8
NGC 777 provides an example of a phenomenon observed in some group-central ellipticals, in which the temperature profile shows a central peak, despite the short central cooling tim…
A JVLA, LOFAR, e-Merlin, VLBA and EVN study of RBS 797: can binary SMBHs explain the outburst history of the central radio galaxy?
Francesco Ubertosi, Marcello Giroletti, Myriam Gitti +9
We present a multi-frequency (144 MHz - 9 GHz) and multi-scale (5 pc - 50 kpc) investigation of the central radio galaxy in RBS 797, by means of JVLA, LOFAR (with international sta…
