The AEGIS -X survey is a 3.4Ms Chandra survey of the Extended Groth Strip (EGS) region, designed primarily for studying the co-evolution of black holes and their host galaxies. The original phase of the survey comprised of 8 contiguous ACIS -I pointings, each with nominal exposure 200ks, covering a total area of approximately 0.67 deg2 in a strip of length 2 degrees. A total of 1325 band-merged sources were detected to a Poisson probability limit of 4×10-6, with limiting fluxes of 5.3 times 10-17 erg cm2 s-1 in the soft (0.5-2 keV) band and 3.8×10-16 erg cm-2 s-1 in the hard (2-10 keV) band. These observations cover a region with excellent supporting ground and space-based panchromatic data (e.g. GALEX , HST/ACS, CFHTLS , Spitzer/IRAC, Spitzer/MIPS, VLA ) and ~20 000 spectroscopic redshifts from the DEEP2 and DEEP3 surveys. The second phase of AEGIS -X has recently been completed and comprises of an additional 1.6Ms in the central 3 pointings in the strip, where the supporting data is strongest. I will present the first results from the new, deeper AEGIS -X survey as well as reviewing some of the key results from the survey to date. In particular I will focus on the optical spectral properties, environment, stellar mass function and morphology of the X-ray sources.
