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
Cosmology is the study of the large scale structure of the Universe, as well as its dynamics. Our group has been involved in the study and development of cosmological models, in particular to explain the accelerated phases of the cosmological evolution, dubbed inflationary phases.
For our latest developments/activities in this area, please see the listing below.
Latest Cosmology News & Events
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.
Research grant in Strong Gravity for M.Sc. holders
A call for a 5-months research grant in Strong Gravity for M.Sc.
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.
