Stellar-mass black holes represent the ultimate stage in the life cycle of massive stars. When part of binary systems,
these black holes exert strong gravitational influences that pull the matter from their companions, giving rise to so-called 'accretion disks.'
These disks are powerful sources of electromagnetic radiation (X-rays in particular), and the properties of the radiation from the disk
carry the imprint of the dynamics, physical processes and geometries of these systems.
The spectral characteristics unravel the fundamental radiation mechanisms, while timing studies delve into the dynamic aspects of these
cosmic systems. Furthermore, X-ray polarization sheds light on the scattering geometry of the hot matter, the orientation of the magnetic field, etc.
In the upcoming seminar, I will discuss the current status of research in this field using the three independent tools mentioned above
and present some of our recent findings. |
