GARRA, the Relativistic Astrophysics and Radio Astronomy Group at the Instituto Argentino de Radioastronomía (IAR), was founded in April 2000 on the basis of collaborations extending since 1993, and with the objective to further the studies on relativistic astrophysics and cosmology in Argentina. Currently,the group also includes researchers and students from other institutions, notably the Facultad de Cs. Astronómicas y Geofísicas of the University of la Plata.
Members Collaborators


The group work over many topics in current astrophysics: compact objects, i.e. pulsars, black holes, exotic stars; unidentified gamma-ray sources; gamma-ray bursts; sources of high-energy cosmic rays; massive stars; gravitation and cosmology. Some members also do research in foundations of science.
