Title: Deep Optical Imaging of XMM/Chandra Deep Fields

Abstract: We are pursuing a multiwavelength campaign to understand the nature of faint X-ray sources. The US Optical Monitor group will obtain as part of its guaranteed time on XMM two deep X-ray exposures, obtaining 0.1 - 10 keV images and spectra of sources as faint as 1 \times 10^- 16 ergs cm^-2 s^-1. Multi-color optical photometry will be essential to help identify and classify the X-ray sources. From previous work done with ROSAT and Chandra deep fields, we have a good understanding of the sources likely to be found in the field and the image qualities we will need, and propose accordingly. This work will help determine the sources of the hard X-ray background, QSO spectral evolution, the temperature evolution of galaxy clusters and help determine the X-ray emission mechanism of the narrow emission line galaxies found in ROSAT surveys.
