It is well known that a classical charged scalar field on Reissner-Nordström spacetime undergoes superradiant scattering. By quantising the field, via canonical quantisation, we investigate the subtleties that superradiant scattering presents in the quantisation of the field.
The XV Black Holes Workshop took place at ISCTE in Lisbon, with a record number of participants and communications (group photo attached). The next edition will take place in Porto, at the Faculty of Engineering, in the 19-20 December 2023.
The last five sessions of the Gr@v group seminars are now on YouTube in our dedicated channel https://www.youtube.com/@Gravchannel. These include the talks from Guilherme Raposo (University of Aveiro), Roberto Emparan (ICREA and Univeristy of Barcelona), Daniela Doneva (University of Tubingen), Andrew Coates (Koc University) and Renate Loll (Radboud University).
The Portuguese Science Foundation (FCT) announced the 6th edition of the individual call to scientific employment stimulus, open from April 4th to May 3rd 2023, for researchers with a Ph.D. and including four different seniority levels. Applications require the support of a host research unit. Researchers wishing to join our group should contact the group coordinator (C. Herdeiro).
Jose Blázquez-Salcedo (Complutense, Madrid), Romain Gervalle (Tours), Fech Scen Khoo (Oldenburg) and Tigran Tchrakian (DIAS, Dublin) visited us in the week of Dec. 5 2022, and lectured in the 1 day Strong Gravity Workshop our group organized.
Part of our group got together on Oct 28 2022 to cellebrate Eugen Radu's faculty position at U. Aveiro and to bid (temporarily) farewell to António Morais' who will embark on a half a year visit to CERN. Great food at "Mestre do Leme" in Aveiro.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
