| --- | --- |
| Description | This cluster of papers focuses on various aspects of black hole astrophysics, including X-ray astronomy, accretion disks, event horizon imaging, gravitational lensing, stellar orbits around black holes, magnetic fields in black hole systems, relativistic jets, and X-ray spectroscopy. The research covers observations and theoretical models related to supermassive black holes at the centers of galaxies, as well as stellar-mass black holes. |
