The detection of gravitational waves is a powerful tool in our quest to deepen our understanding of fundamental physics. To make the most out of this tool, we need to accurately simulate the whole process of gravitational wave emission, propagation and detection by interferometers.
NewFunFiCO kick off meeting
The NewFunFiCO Staff Exchange network had its kick off meeting on January 19th 2023. The meeting was virtual, but it promised very interesting real work and synergies to come in the next four years!

The idea that the Planck length can act as a regulator of UV divergences has inspired various approaches to quantum gravity, but a possibly much larger width for the ground state emerges in the (non-perturbative) quantisation of the Oppenheimer-Snyder model of dust collapse that naturally recovers Bekenstein’s area law.

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.
XVI Black Holes Workshop in Porto
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.
Five new Gr@v Seminars are now online!
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 Madrid Winter Workshop took place at Complutense University, Madrid, from 12-15 December 2023. C. Herdeiro was one of the invited speakers.
6-years researcher positions at Gr@v
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).
