11th School on Astrophysics and Gravitation
The 11th School on Astrophysics and Gravitation will take place at Instituto Superior Técnico in Lisbon, from 1-6 September 2023. C. Herdeiro and M. Zilhão are two of the lecturers. More info here.
Great visits
At the end of June 2023 we have enjoyed the visits of Juan Carlos Degollado (UNAM - Mexico), Nico Sanchis Gual (Valencia - Spain) and Mikaela Carrasco (USFQ - Ecuador). Nine nationalities in this group photo taken on June 28 - science brings people together!
European Einstein Toolkit Meeting 2023
Our group organised the European Einstein Toolkit Meeting 2023, at the University of Aveiro, 19-23 June 2023. We had excellent speakers throughout the week, and everybody had a great time. Next year's meeting should be held in Amsterdam; hope to see everyone there!

Cosmology from galaxy phase-space information and a bit of halo-galaxy connection
Speaker
Natali de Santi (Flatiron Institute and University of Sao Paulo)
Event date
Venue
Online (only)
Event type
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.
APS Journal Club
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.
