Abstract

With ≈ 2 Ms of exposure, the Chandra Deep Field-North (CDF-N) survey provides the deepest view of the Universe in the 0.5-8.0 keV band. Five hundred and three (503) X-ray sources are detected down to on-axis 0.5-2.0 keV and 2-8 keV flux limits of ≈ 1.5 × 10-17 erg cm-2 s-1 and ≈ 1.0 × 10-16 erg cm-2 s-1, respectively. These flux limits correspond to L0.5-8.0 kev ≈ 3 × 1041 erg s-1 at z = 1 and L0.5-8.0 kev ≈ 2 × 1043 erg s-1 at z = 6; thus this survey is sensitive enough to detect starburst galaxies out to moderate redshift and Seyfert galaxies out to high redshift. We present the X-ray observations, describe the broad diversity of X-ray selected sources, and review the prospects for deeper exposures.
