Abstract:<br />
According to galaxy formation models, cluster ellipticals formed in high density<br />
regions through hierarchical merging <strong>of</strong> gas rich sub−components. In local<br />
ellipticals, the strong correlation observed between black hole and bulge mass<br />
implies that galaxy formation is inextricably linked to the build up <strong>of</strong><br />
supermassive black holes. We have found 6 high redshift, X−ray luminous, but<br />
heavily absorbed AGN, embedded in strong bursts <strong>of</strong> star formation revealed in<br />
the submillimetre. Our SCUBA survey shows that the immediate vicinities <strong>of</strong> these<br />
objects contain large overdensities <strong>of</strong> ultraluminous star−forming galaxies which<br />
will evolve to form clusters. Here we propose to use SPITZER to measure the<br />
stellar masses <strong>of</strong> the companion galaxies, search for buried AGN, and thereby<br />
determine the sequence in which the cluster ellipticals are assembled, form<br />
their stars, and grow their massive black holes.<br />

Abstract:<br />
We propose a very deep (total 800ks/field) Chandra survey <strong>of</strong> 0.25 deg2 covering<br />
3 contiguous fields in the Extended Groth Strip, which have exceptional<br />
multiwaveband coverage obtained by the AEGIS project. These data, in combination<br />
with the CDF North and South, will provide a definitive measurement <strong>of</strong> the<br />
evolution <strong>of</strong> faint, X−ray selected AGN from z=3−4, where the optical number<br />
counts start to drop dramatically. In combination with ultradeep Spitzer data in<br />
the same region, this survey will also provide a crucial step forward towards a<br />
more complete census <strong>of</strong> AGN activity and the importance <strong>of</strong> Compton thick AGN at<br />
high z, with associated implications for the total accretion budget <strong>of</strong> the<br />
universe.<br />
