Cosmology with one galaxy: An analytic formula relating with galaxy properties
Kito Liao, Francisco Villaescusa-Navarro, Romain Teyssier +1
Standard cosmological analyses typically treat galaxy formation and cosmological parameter inference as decoupled problems, relying on population-level statistics such as clusterin…
Field-level simulation-based inference with galaxy catalogs: the impact of systematic effects
Natalà S. M. de Santi, Francisco Villaescusa-Navarro, L. Raul Abramo +11
It has been recently shown that a powerful way to constrain cosmological parameters from galaxy redshift surveys is to train graph neural networks to perform field-level likelihood…
Exploring the halo-galaxy connection with probabilistic approaches
Natália V. N. Rodrigues, Natalà S. M. de Santi, L. Raul Abramo +1
The connection between galaxies and dark matter halos encompasses a range of processes and play a pivotal role in our understanding of galaxy formation and evolution. Traditionally…
