Hard X-ray selected giant radio galaxies -- III. The LOFAR view
G. Bruni, M. Brienza, F. Panessa +12
Giant radio galaxies (GRGs), with extended structures reaching hundreds of kpc, are among the most spectacular examples of ejection of relativistic plasma from super-massive black…
Soft gamma-ray selected giant radio galaxies: an update
L. Bassani, F. Ursini, A. Malizia +9
We present an update on the sample of soft gamma-ray selected giant radio galaxies (GRGs) extracted from INTEGRAL/IBIS and Swift/BAT surveys; it includes 8 new sources and one cand…
A broadband X-ray view of the NLSy1 1E 0754.6+392.8
R. Middei, F. Tombesi, F. Vagnetti +8
The soft X-ray band of many active galactic nuclei (AGNs) is affected by obscuration due to partially ionised matter crossing our line of sight. In this context, two past XMM-Newto…
Radiation spectra of warm and optically thick coronae in AGN
P. -O. Petrucci, D. Gronkiewicz, A. Rozanska +9
A soft X-ray excess above the 2-10 keV power law extrapolation is generally observed in AGN X-ray spectra. Presently there are two competitive models to explain it: blurred ionized…
The coronal temperature of NGC 4388 and NGC 2110 measured with INTEGRAL
F. Ursini, L. Bassani, A. Malizia +4
We aim to measure the physical properties of the hot X-ray corona of two active galactic nuclei, NGC 4388 and NGC 2110. We analysed the hard X-ray (20-300 keV) INTEGRAL spectrum in…
Probing restarting activity in hard X-ray selected giant radio galaxies
G. Bruni, F. Ursini, F. Panessa +13
With their sizes larger than 0.7 Mpc, Giant Radio Galaxies (GRGs) are the largest individual objects in the Universe. To date, the reason why they reach such enormous extensions is…
