Dettagli del corso

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.
