I - Introduction to high-energy astrophysics and instrumentation
Ia - Detection techniques for high-energy photons. X-ray and Gamma-ray detectors. Wolter-type telescopes and coded-aperture masks. Cherenkov radiation.
Ib - History of high-energy astrophysics and properties of the main X-ray and Gamma-ray observatories.
Ic - Main physical parameters describing the accretion of matter onto compact objects: radial and disk accretion, mass transfer, radiative efficiency, Eddington luminosity, outflows.
Id - Brief description of the main emission mechanisms in high-energy astrophysics. Blackbody, bremsstrahlung, synchrotron, Compton scattering and inverse Compton scattering. Collisional ionization and photoionization, line emission and absorption.
II - Galactic high-energy sources
IIa - Compact sources: X-ray emission from stars in the main-sequence and pre main-sequence. White dwarfs, cataclysmic variables, novae, pulsars, pulsar wind nebulae, and neutron stars. Physical properties of accreting neutron stars and stellar mass black holes. Classification of X-ray binaries.
IIb - Diffuse sources: Supernova remnants. The Galactic center region and the high-energy emission related to SgrA*. Fermi Bubbles.
III - Extragalactic high-energy sources
IIIa - Compact sources: Active galactic nuclei (AGN), quasars, blazars. Electromagnetic counterparts of astro-particle sources. Ultraluminous X-ray sources (ULXs).
IIIb - Diffuse sources: Starburst galaxies. Cluster of galaxies.
