Offered at the school The Sound of Space-time: The Dawn of Gravitational Wave Science at ICTP-SAIFR
Credits: 5 h
This short course gives a general overview of black hole astrophysics. I will give a primer on the physics necessary for a broad understanding of accreting black holes and their observational manifestation—particularly in electromagnetic waves.
Topics covered will include: • general overview of the phenomenology of black holes observed in active galactic nuclei (AGN), X-ray binaries and gamma-ray bursts (GRBs) • primer on general relativity, fluid dynamics and radiative processes • accretion disks, relativistic jets and their observations • co-evolution of BHs and galaxies • massive binary BH systems.
Along the way, I will present cutting-edge results across the electromagnetic spectrum from telescopes such as Chandra, XMM-Newton, Swift, Fermi, GRAVITY and the Event Horizon Telescope, as well as new developments in numerical simulations of black hole accretion enabled through the latest supercomputers.
