Operations CXO Status Report

Friday 11 May 2018 9.00am EDT

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

A Chandra image release was issued on May 9 describing archival analysis suggesting thousands of stellar-mass black holes are located near the center of our galaxy. The authors extrapolated their analysis from the detection of a dozen X-ray binaries which they suspect host a stellar-mass black hole. Only the brightest X-ray binaries containing black holes are likely to be detectable at the distance of the Galactic Center. For details see: http://chandra.si.edu/photo/2018/sgra_swarm/

The schedule of targets for the next week is shown below and includes an observation of Alpha Centauri, which was accepted as a Director's Discretionary Time Target of Opportunity on Feb 16.
