An X-ray View of the Most Luminous Outflowing Dust-Obscured Quasars

We propose XMMNewton observations of eight recently discovered hyperluminous,heavily reddened quasars at the main epoch of galaxy and blackhole growth atzvirgul23. The sample, selected from large area infrared surveys, has high qualityrestframe optical spectroscopic coverage, and luminous OIII line emissionwith signatures of outflowing gas. This proposal will increase the number ofsuch sources with Xray coverage ninefold, completing the sample, and will allowus to achieve the goal of directly constraining circumnuclear obscuration andaccretion luminosities. The combination of high quality XMM spectra with theexisting multiwavelength data will allow us to assess the importance ofradiative pressure on dust, a mode of feedback which is expected to be prevalent in these systems. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
