High Energy Astrophysics

ll corso intende fornire allo studente una visione pancromatica dei fenomeni Astrofisici, con particolare enfasi sui processi delle Alte Energie, attraverso un approccio che combini parte teorica, sperimentale e fenomenologica. Particolare risalto sarà dato alle evidenze osservative dei fenomeni descritti attraverso l’uso delle moderne tecniche astronomiche. This class will provide the student with a pancromatic view of the Universe, with special emphasis on High Energy processes, using an approach which combines theoretical, experimental and phenomenological aspects. Particular attention will be devoted to the observational data obtained through moderns astronomical techniques, supporting the interpretation of high energy phenomena. Programma / Topics: Il corso si articola in 3 parti: I parte - Introduzione ai processi fisici di interazione radiazione-materia di particolare rilevanza per l’astrofisica delle alte energie: assorbimento fotoelettrico, Bremsstrahlung, scattering Thomson e Compton, Comptonizzazione, emissione di Sincrotrone; II parte - Tecniche di rivelazione per le alte energie e confronto con quelle dell’astronomia tradizionale: telescopi X e gamma, rivelatori a scintillazione, contatori proporzionali, dispositivi a stato solido (CCD), coded-masks; reticoli di diffrazione; III parte - Fenomeni astrofisici caratterizzati da emissione ad alta energia: sorgenti di raggi cosmici, corone stellari, supernovae, gamma ray bursts, sistemi binari in accrescimento, nuclei galattici attivi, aloni galattici e di ammasso. The course is divided in 3 parts: Part I - Introduction to high energy processes: photoelectric absorption, Bremsstrahlung, Thomson and Compton scattering, Comptonization, Synchrotron emission; Part II - Detection techniques in High-Energy astrophysics and comparison with optical /ground-based astronomy: X-ray and gamma telescopes, scintillators, proportional counters, solid state devices (CCD), coded-masks; diffraction gratings; Part III - Astrophysical phenomena characterized by high-energy emission: cosmic ray sources, stellar coronae, supernovae, gamma-ray bursts, accreting binary systems, active galactic nuclei, galaxy and cluster gaseous halos.
