The Extended Chandra Deep Field-South Survey

This WWW site presents results from the Extended Chandra Deep Field-South survey. This survey is composed of four 250 ks Chandra ACIS-I observations flanking the original Chandra Deep Field-South. The total solid angle covered by these observations is about 1100 sq. arcmin, and nearly 800 X-ray sources are detected.

The basic X-ray and optical properties of the detected sources indicate a variety of source types. Active galaxies dominate the number of detected sources, but a significant number of starburst and normal galaxies are detected as well. Further investigations of the detected sources are underway.
