The Two Micron AllSky Survey(2MASS) is compiling a sample of new, red, activegalaxies (AGN) whose number density rivals that of optically selected AGN. Theirtypically high optical polarization suggests substantial obscuration toward thenuclear energy source. Chandra observations show weak, hard Xray emissioncompared with normal, lowredshift AGN suggesting that these, mostlybroadlined, AGN represent the Xray absorbed population predicted by modellingof the Cosmic Xray Background (CXRB). We request XMM time for a subset of thesesources to obtain higher signaltonoise spectra to: 1: determine the spectralindex and absorbing column density, 2. determine their contribution to the CXRB,3. look for reflected/scattered light expected from their high polarisation. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
