タイトル | “Production and absorption of gamma rays with stars in neighbourhood of supermassive black holes.” |
概要 | Supermassive black holes (SMBH) tend to be surrounded by massive star clusters. Under certain conditions those stars might affect the gamma-ray emission from SMBH-jet system. In this seminar I will present a few theoretical scenarios in which the encounter with a star leads either to production of a gamma-ray flare, or to an absorption feature in the gamma-ray spectrum of the source. |
