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.
Group meeting in São Pedro do Sul
Our group organized the "State of the art techniques in Strong Gravity" Meeting, in São Pedro do Sul 26-28 April 2023 as a retreat type meeting to exchange ideas. The inspiring discussions will certainly foster new research!
Seminar at the Galileo Galilei Institute
Gr@v Ph.D. student E. Costa presented a seminar on the "Proca-Higgs model" in the Mini-Workshop "New Horizons for Horizonless Physics" at the Galileo Galilei Institute in Florence, Italy.
Colloquium at Tubingen
C. Herdeiro presented an invited colloquium at the U. Tubingen. Thank you to D. Doneva and the whole group for the warm and scientifically stimulating hospitality!
Maurício Richartz visit
Prof. Maurício Richartz, from ABC Federal University, State of São Paulo, Brazil, visited Gr@v in March-April 2023, to discuss analogue models of gravity and other topics. Thank you for your visit Maurício and see you soon!
Prospects for multi-probe cosmology as gravity and inflation probes

Venue
Hybrid Sala Sousa Pinto (Math dpt) and Zoom
Event type
The next decade will see an overwhelming number of cosmological surveys coming online. The Square Kilometre Array Observatory (SKAO) will, among several other science cases, map the distribution of cold neutral Hydrogen in the Universe using its spin-flip transition emission line at rest of 21cm or 1.4GHz and a novel technique called Intensity Mapping (IM).
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.
