    • Resolving the soft X-ray ultra fast outflow in PDS 456 

      Reeves, James; Braito, Valentina; Chartas, George; Hamann, Fred; Laha, Sibasish; Nardini, Emanuele (2020-04-26)
      Past X-ray observations of the nearby luminous quasar PDS 456 (at z=0.184) have revealed a wide angle accretion disk wind (Nardini et al. 2015), with an outflow velocity of ∼−0.25c, as observed through observations of its ...

    • Resolving the X-ray obscuration in a low flux observation of the quasar PDS 456 

      Reeves, James; Braito, Valentina; Nardini, Emanuele; Hamann, Fred; Chartas, George; Lobban, Andrew; O'Brien, Paul; Turner, Jane (2018-09-19)
      Simultaneous XMM-Newton, NuSTAR and HST observations, performed in March 2017, of the nearby (z=0.184 ) luminous quasar PDS 456 are presented. PDS 456 had a low X-ray flux compared to past observations, where the first of ...
