Superradiance

Vitor Cardoso is an Assistant Professor (``Com Agregação'') of Physics at Instituto Superior Técnico, Portugal and a Visiting Fellow at the Perimeter Institute, Canada. He is an ERC grantee of the European Research Council and an outstanding Referee for the American Physical Society. His research interests include black hole physics, gravitational-wave physics and General Relativity. Paolo Pani is a Marie Curie Fellow at Sapienza University of Rome and a FCT Researcher at CENTRA-IST in Lisbon. He is an outstanding Referee for the American Physical Society and a former research fellow at the Harvard-Smithsonian Center for Astrophysics. His research interests include black holes, foundations of General Relativity and relativistic astrophysics. In 2011, his PhD thesis on blackhole perturbation theory was awarded the Fubini Prize of the Italian Institute for Nuclear Physics. Richard Brito is completing a doctorate in the gravity group at CENTRA-IST in Lisbon. His research interests include black holes, General Relativity and alternative theories of gravity. His PhD thesis focusses on studying dark matter candidates and alternative theories of gravity using compact objects. In 2013 he was awarded the "Prémio Estímulo à Investigação" by the Fundação Calouste Gulbenkian, a prize rewarding young researchers with strong research proposals.
