A broad-band X-ray view of the warm absorber in radio-quiet quasar MR2251-178

Abstract:

We present the analysis of a new broad-band X-ray spectrum (0.6-180.0keV) of the radio-quiet quasar MR2251-178 which uses both Suzaku and Swift/Burst Alert Telescope data. In accordance with previous observations, we find that the general continuum can be well described by a power law with Γ= 1.6 and an apparent soft excess below 1keV. Warm absorption is clearly present, and absorption lines due to the Feunresolved transition array, FeL (Fexxiii-xxiv), Sxv and Sxvi are detected below 3keV. At...
