X-ray flaring in PDS 456 observed in a high-flux state
G. A. Matzeu, J. N. Reeves, E. Nardini +3
We present an analysis of a \,ks (net exposure) \textit{Suzaku} observation, carried out in 2007, of the nearby () luminous (L\,erg\,s)…
A deep X-ray view of the bare AGN Ark 120. II. Evidence for Fe K emission transients
E. Nardini, D. Porquet, J. N. Reeves +3
We report on the results from a large observational campaign on the bare Seyfert galaxy Ark 120, jointly carried out in 2014 with XMM-Newton, Chandra, and NuSTAR. The fortunate lin…
A deep X-ray view of the bare AGN Ark 120. I. Revealing the Soft X-ray Line Emission
James Reeves, Delphine Porquet, Valentina Braito +3
The Seyfert 1 galaxy, Ark 120, is a prototype example of the so-called class of bare nucleus AGN, whereby there is no known evidence for the presence of ionized gas along the direc…
Broadband short term variability of the quasar PDS 456
G. A. Matzeu, J. N. Reeves, E. Nardini +4
We present a detailed analysis of a recent ks net exposure \textit{Suzaku} observation, carried out in 2013, of the nearby () luminous (L erg…
Discovery of Broad Soft X-ray Absorption Lines from the Quasar Wind in PDS 456
James Reeves, Valentina Braito, Emanuele Nardini +5
High resolution soft X-ray spectroscopy of the prototype accretion disk wind quasar, PDS 456, is presented. Here, the XMM-Newton RGS spectra are analyzed from the large 2013-2014 X…
Short term X-ray spectral variability of the quasar PDS 456 observed in a low flux state
Gabriele A. Matzeu, James N. Reeves, Emanuele Nardini +4
We present an analysis of the 2013 Suzaku campaign on the nearby luminous quasar PDS 456, covering a total duration of ~1 Ms and a net exposure of 455 ks. During these observations…
