High-Energy Radiation in Galactic Compact Sources, Valenti Bosch-Ramon

SEMINAR DATE: Feb 10 (Thursday)
TIME: 17:00 h
SPEAKER: Dr. Valenti Bosch-Ramon
AFFILIATION: DIAS, Dublin, Ireland

SEMINAR TITLE: High-Energy Radiation in Galactic Compact Sources
SEMINAR LANGUAGE: English

ABSTRACT:
Galactic compact sources have been considered a potential class of  
gamma-ray emitting objects for many years, but it was not until  
recently that it was firmly established by satellite-borne GeV and  
ground-based TeV instruments. These sources, basically all of them  
pertaining to the category of gamma-ray binaries, can be very  
luminous, and present strong variability and high acceleration  
efficiencies, being their high-energy emission likely produced in  
powerful outflows suffering internal and external shocks. Since they  
are compact objects and strong radiation fields tend to be present,  
pair creation cannot be neglected. In this talk, I will briefly  
summarize the main properties of these objects, as well as discuss  
open questions regarding the physics behind their emission.
