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 190\,ks (net exposure) \textit{Suzaku} observation, carried out in 2007, of the nearby (z=0.184) luminous (Lbol​∼1047\,erg\,s−1)…

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 500 ks net exposure \textit{Suzaku} observation, carried out in 2013, of the nearby (z=0.184) luminous (Lbol​∼1047 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…
