The Ultrafast Outflow of the Lensed z=1.51 AGN HS 0810+2554

Massive and ultrafast wideangled outflows from AGN are one of the proposedfeedback mechanisms that may provide the coupling of kinetic energy betweenquasars and their host galaxies. To further our understanding of the AGNa??srole in this process we propose joint Chandra and XMM observations of theoutflow of the z1.5 AGN HS 0810+2554. The factor of 120 lensing magnificationof HS0810 makes this source exceptionally bright compared to other quasars withdetected outflows at similar distances. We will also study the short andlongterm variability of the Xray outflow and the correlation of Xray windproperties to the Xray and UV spectral properties. The variability andcorrelation results will provide insight into the acceleration mechanism of the wind. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
