Evidence for a radiatively driven disc-wind in PDS 456?

G. A. Matzeu, J. N. Reeves, V. Braito +5

We present a newly discovered correlation between the wind outflow velocity and the X-ray luminosity in the luminous (Lbol​∼1047ergs−1) nearby (z=0.184)…

astro-ph.HE2016

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…

Black hole feedback in the luminous quasar PDS 456

E. Nardini, J. N. Reeves, J. Gofford +17

The evolution of galaxies is connected to the growth of supermassive black holes in their centers. During the quasar phase, a huge luminosity is released as matter falls onto the b…
