Journées Relativistes de Tours
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.
Cosmology News & Events
Research grant in Strong Gravity for M.Sc. holders
A call for a 5-months research grant in Strong Gravity for M.Sc.
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.
IberiCos 2023
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.
Meeting with a scientist
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.
"Children are not things to be molded, but are people to be unfolded"
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!
Research grant in Strong Gravity for M.Sc. holders
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.

Celebration group lunch
Celebrating the recent "UA Investigador" prize and the group's many (great) guests on Mar 7th 2023. Thank you to Prof. Carolina Benone (U. F. do Pará, Brazil) for the visit and welcome to Prof. Maurício Richartz (U. F. ABC, Brazil), who is joining us for a month. And we also got the short visit of Francisco Duque, from IST-Lisbon, who presented the group seminar on Mar 8th.
