Studying microquasars with X-ray polarimetry |
|
Abstract |
While timing and spectroscopy of microquasars are well established techniques, X-ray polarimetry is lagging behind, despite its widely recognized importance in providing vital information on the phsyics and geometry of these sources, including strong gravity effects. Happily, this will change very soon, thanks to the approval by NASA of IXPE (the Imaging X-ray Polarimetry Explorer), the next mission in the SMEX program, to be launched in 2021. Moreover, X-ray polarimeters will be part of the detectors suite of eXTP, a chinese-led mission currently under study. In this contribution, the main scientific results expected by IXPE on microquasars (black hole spin measurement, geometry of the hot corona, jet contribution) will be discussed. |
