ToO Observations of the Microquasar GRS 1915+105 in Quiescence
Abstract
In July 2018 the black hole binary GRS 1915+105 underwent a transition to unprecedented low-flux state, which might precede the end of a 30-years-long outburst of this source. We propose to observe this system with three Chandra observations, each 30-ks long (plus four Swift observations, 0.5-ks each), should its outburst end during the 24th observing cycle. GRS 1915+105 has never been observed in quiescence: observations in this state will allow us to measure the spectrum and test the proposed models for quiescent emission in black-hole binaries.
