Within the NewFunFiCO network, coordinated by our group, we are co-organizing a workshop on fundamental fields and compact objects: new opportunities, at ICF - UNAM - Campus de Morelos, Mexico, from October 4-6 2023.

The Journées Relativistes de Tours, France, took place from 31 May - 2 June 2023 discussing the latest developments in the field. C. Herdeiro and E. Radu were two of the invited speakers.

In this talk, I will give an overview of how to do field-level likelihood-free inference with galaxy catalogs.
More specifically, only using phase-space information, I will show how to convert galaxy catalogs into graphs.
I will explain how to use graph neural networks, associated with moment neural networks, to constrain Omega matter.

American Physical Society invited the authors of the paper "Exotic Compact Objects and the fate of the light ring instability" to participate in the APS Journal Club (JC), dedicated to selected papers published in Physical Review Letters. It was the first time this JC was dedicated to a gravity paper. The video recording of the session will be found in the JC webpage.

Miguel attended the IberiCos 2023 meeting in Ponte de Lima, the oldest village in Portugal. Here he is together with former Gr@v member João Rosa.

Gr@v member Miguel Zilhão was the guest for the activity "Meeting with a scientist", organized by the outreach centre Fábrica.The audience was a group of 4th grade students from the Primary Schools of Glória and São Jacinto. They were all very curious about the Universe and asked a lot of interesting questions.

Our group visited Colégio de Lamas, in Santa Maria da Feira, to explain basic concepts about Earth and Space. Inevitably, the questions end up discussing black holes!

A call for one 1-year research grant in Strong Gravity for M.Sc. holders enrolled in a doctoral programme at Aveiro University, within the research grant “Gravitational waves and black holes as ultralight dark matter particle detectors", CERN/FIS-PAR/0024/2021, is open from 20 March to 10 April 2023.  See attached document for details (in Portuguese) or the Euraxess announcement (in English) here.
