XMM-Newton spectroscopy of high-redshift Dust Obscured Galaxies

A population of Dust Obscured Galaxies (DOGs; (F(24um)/F(R)>1000 and F(24um)> 1mJy) at z>1, likely associated with an obscured phase in the quasar lifetime,has recently been revealed. Redshift distribution, broadband photometry andbolometric luminosities of DOGs indicate that these systems may represent anearly dustembedded phase of powerful AGN activity. Due to low space density,DOGs are rarely detected even in the deepest Xray surveys. However, lowqualityXray spectroscopy has revealed the common presence of highly obscured AGN intheir nuclei. XMMNewton is the ideal telescope to study their largelyunexplored Xray properties. We propose here to obtain a high signaltonoiseXray spectrum for two unique, opticallyidentified DOGs from the Bootes survey. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
