The annual RAGtime workshop has been organized by the Relativistic Astrophysics Group (RAG) at the Institute of Physics since 1999. The scientific focus of the workshop is mainly devoted to current issues of relativistic astrophysics of black holes and neutron stars. It is a workshop of lectures by professors and students from the Institute of Physics and abroad where transition of knowledge and experience happens, and a workshop of useful discussions and cooperation between participants.

The workshop focuses on comparing theoretical models of compact objects and comparing them with actual observed data. Special attention is traditionally paid to numerical modeling of the behavior of matter in the environment of strong gravity, accretion processes, cosmology, mathematical aspects of the general theory of relativity and alternative theories of gravity.

Last but not least, we deal with the topics of lectures and discussions about international cooperation on current and future X-ray missions in space.

There is also a proceedings called "Proceedings of RAGtime" which is released every three years. It contains articles on lectures and is indexed in the Scopus database. The proceedings are published on site and online.
