X-ray absorption variability in NGC 4507
Andrea Marinucci, Guido Risaliti, Junfeng Wang +5
We present a complete spectral analysis of an XMM-Newton and Chandra campaign of the obscured AGN in NGC 4507, consisting of six observations spanning a period of six months, rangi…
Unification of X-ray winds in Seyfert galaxies: from ultra-fast outflows to warm absorbers
F. Tombesi, M. Cappi, J. N. Reeves +4
The existence of ionized X-ray absorbing layers of gas along the line of sight to the nuclei of Seyfert galaxies is a well established observational fact. This material is systemat…
The Suzaku view of highly-ionised outflows in AGN: I - Statistical detection and global absorber properties
Jason Gofford, James N. Reeves, Francesco Tombesi +4
We present the results of a new spectroscopic study of Fe K-band absorption in Active Galactic Nuclei (AGN). Using data obtained from the Suzaku public archive we have performed a…
The accretion disc, jets and environment of the intermediate mass black hole candidate ESO 243-49 HLX-1
N. A. Webb, D. Barret, V. Braito +13
The Ultra Luminous X-ray (ULX) source HLX-1 in the galaxy ESO 243-49 has an observed maximum unabsorbed X-ray luminosity of 1.3e42 erg/s (0.2-10.0 keV). From the conservative assum…
Decoupling absorption and continuum variability in the Seyfert 2 NGC 4507
V. Braito, L. Ballo, J. N. Reeves +3
We present the results of the Suzaku observation of the Seyfert 2 galaxy NGC 4507. This source is one of the X-ray brightest Compton-thin Seyfert 2s and a candidate for a variable…
Radio-to-gamma-ray Monitoring of the Narrow-Line Seyfert 1 Galaxy PMN J0948+0022 from 2008 to 2011
L. Foschini, E. Angelakis, L. Fuhrmann +39
We present more than three years of observations at different frequencies, from radio to high-energy gamma-rays, of the Narrow-Line Seyfert 1 (NLS1) Galaxy PMN J0948+0022 (z=0.585)…
