The series of the annual RAGtime workshops has been held at the Institute by the Relativistic Astrophysics Group (RAG) since 1999. Its scientific scope is devoted to current problems of relativistic astrophysics mainly focused on the physics of black boles and neutron stars. The workshop is attended by multiple experts in the field and allows for many valuable discussions and interactions between the participants.
The recent volumes have been co-organized within the framework of the research projects MSM 4781305903 and Centre for Theoretical Astrophysics, and since January 2012 within the project CZ.1.07/2.3.00/20.0071 "Synergy" aimed to support international collaboration of the Institute.
