During the last week Chandra completed the observing schedule as planned. A real-time procedure was executed on Aug 7 to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer. A Chandra press release was issued on Aug 8 describing evidence for the farthest "cloaked" black hole found to date. These massive, growing black holes, surrounded by gas, are difficult to identify at this early phase of their evolution, before they break free of their obscuring environment. At only about 6% of the current age of the universe, this would be the first indication of a black hole hidden by gas at such an early time in the history of the cosmos, 850 million years after the Big Bang. For more information see: http://chandra.cfa.harvard.edu/press/19_releases/press_080819.html The schedule of targets for the next week is shown below and includes an observation of EXO1846-031, which was accepted as a Target of Opportunity on Aug 1, two observations of SgrA* coordinated with NuSTAR, and an observation of SDSSJ113323+55041 coordinated with VLA. |
