The Xray properties of z~2 optically faint radio galaxies

Scott Chapman, Institute of Astronomy, University of Cambridge

We have used a combination of Chandra Xray and MERLIN-20cm radio observations to constrain the AGN properties in a large sample of our z~2 optically faint radio sources. We highlight peculiar examples of AGN identified solely through their ultra-compact radio emission, but undetected in 2Msec of Chandra Xray observations, and showing no optical or mid-IR signatures of AGN.
