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!

Asymmetric binaries as astrophysical laboratories to probe new fundamental fields
Speaker
Andrea Maselli (GSSI, INFN)
Event date
Venue
Hybrid Sala 11.2.21 (Math dpt) and Zoom
Event type
Asymmetric binaries provide a unique phenomenology within the family-tree of coalescing systems, which makes them golden targets for future gravitational wave interferometers. Assembled by a compact object orbiting around a more massive body, they can emit gravitational waves from the milliHz to the Hz regime, depending on the size of their components.
Testing Fundamental Physics with the Event Horizon Telescope
Speaker
Lia Medeiros (Princeton - Institute of Advanced Study)
Event date
Venue
Online (only)
Event type
New horizon-scale images of the Galactic Center black hole Sagittarius A* (Sgr A*) recently published by the Event Horizon Telescope (EHT) allow for new strong-field tests of the Kerr metric in a previously unexplored regime. I will discuss the recent EHT observations of Sgr A* with a particular focus on how these new results can be used to test fundamental physics.
Multiple black holes and resonances
Speaker
Béatrice Bonga (Radboud University)
Event date
Venue

Event type
Resonances are ubiquitous in nature. In this talk, I will focus on resonances due to the interaction of two black holes orbiting a central massive black hole. Such tidal resonances will generically occur for Extreme Mass Ratio Inspirals (EMRIs), if nearby compact objects exist.
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).

Madrid Winter Workshop
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).
The fate of the light-ring instability in PRL
The recent Gr@v work on the fate of the Light Ring instability (arXiv:2207.13713) will appear in the prestigious Physical Review Letters.
Visits of Blazquez-Salcedo, Gervalle, Khoo and Tchrakian
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.
