Accreting Black Holes in the new era of X-ray polarimetry missions
This research project, no. 21-06825X, is funded by the Czech Science Foundation as the EXPRO type of grant projects under the Discipline Commitee EX1 - Mathematics and Physics 1 in the period of 1/1/2021 - 31/12/2025.
The project studies the environment in the closest vicinity of accreting black holes in Galactic X-ray binaries. While the black hole form their fundamental element, these systems typically consist of two additional main constituents - an accretion disk and a corona. With the help of the most up-to-date methods in X-ray polarimetry and variability research, including traditional approach of spectroscopy, we study these components and their mutual physical interactions in X-ray band. To this aim we develop new numerical models that link all the acting components together as a whole. In this project a compact team has been created, consisting of Czech scientists who actively participate on preparations of new X-ray polarimetric missions, Imaging X-ray Polarimetry Explorer (IXPE, NASA, 2021) and enhanced X-ray Timing and Polarimetry mission (eXTP, China- Europe, 2027), including European large observatory Advanced Telescope for High Energy Astrophysics (Athena, ESA, 2031), and in this way the project supports Czech participation in the scientific programme of these space missions.
