The Chandra Deep Field-North Survey

This site presents results from the Chandra Deep Field-North survey; this is the deepest 0.5-8.0 keV survey ever made, and nearly 600 X-ray sources are detected. The survey is comprised of 2 Ms of Chandra ACIS-I exposure covering 448 sq. arcmin.

Below are refereed papers, conference proceedings, press releases, and data products. The more recent papers are listed first (in each category) and generally supersede the older ones.
