Operations CXO Status Report

Friday 25 October 2019 9.00am EDT

During the last week Chandra completed the observing schedule as planned.

A real-time procedure was executed on Oct 23 to perform full-frame dark current readouts of the Aspect Camera Assembly CCD.

A Chandra image release was issued on Oct 24 showing a mega-merger of four galaxy clusters in Abell 1758 that has been observed by Chandra and other telescopes. Abell 1758 contains two pairs of galaxy clusters, each on their way to merging and containing hundreds of galaxies embedded in large amounts of hot gas and unseen dark matter. Eventually these two pairs of clusters will collide to form one of the most massive objects in the Universe. For more details see: https://chandra.harvard.edu/photo/2019/a1758/

Of note this week was the release on Oct 24 of the Chandra Source Catalog (CSC) version 2.0. This release contains 317,167 unique X-ray sources covering 550 square degrees of the sky. With approximately 928,000 individual detections, the CSC 2.0 is the largest X-ray catalog to date. This catalog makes X-ray astronomy studies readily accessible to the entire scientific community.
