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.

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.
