X-RAY EXCAVATION OF SCUBA-LUMINOUS QUASARS

Observations of luminous, highredshift quasars in the submillimetre bandsuggest that a high fraction of these AGN coexist alongside powerful,dustenshrouded star formation in their host galaxies. They thus bear all thehallmarks of youthful galaxies, inhabiting an environment rich in gas and dust.We propose to obtain sensitive XMMNewton spectroscopy of highredshift,submmluminous quasars from our intensive, multiwavelength study. This willestablish whether there is any correlation between anomalous Xray spectra (e.g.intrinsic absorption) and the presence of starbursts and/or large masses ofmolecular gas. This has significant implications for our understanding of therelation between the formation of AGN and their massive host galaxies. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
