We present results from a Chandra study of the Hubble Deep Field (HDF) and its environs obtained using 237 ks of data collected by the Advanced CCD Imaging Spectrometer (ACIS). This is one of the deepest X-ray observations ever reported, and we have detected at least six X-ray sources in the HDF itself. Comparing these with objects seen in multiwavelength HDF studies shows positional coincidences with the extremely red object NICMOS J123651.74+621221.4, an active galactic nucleus (AGN), three elliptical galaxies, and one nearby spiral galaxy. We also place X-ray upper limits on AGN candidates found in the HDF, and we present the tightest constraints yet on X-ray emission from the SCUBA submillimeter source population. Most of the submillimeter sources appear to be dominated by star formation or have AGN with Compton-thick tori and little circumnuclear X-ray scattering. Furthermore, we highlight optical spectroscopy results for X-ray sources detected in the full ACIS field of view, using data collected by the Hobby-Eberly and Keck Telescopes. We describe future plans to extend this research.

We acknowledge the financial support of NASA grant NAS 8-38252.
