Dianoga simulations of galaxy clusters and groups: Properties of the baryonic components
Stefano Borgani, Alice Damiano, Elena Rasia +12
We introduce the Dianoga set of cosmological simulations of galaxy clusters and groups, specifically aimed at studying the impact of the implementation of AGN feedback and star for…
Baryonic assembly bias in X-ray-selected galaxy groups and clusters: insights from the Magneticum simulation
Ilaria Marini, Tiago Castro, Paola Popesso +5
Galaxy groups and clusters trace the large-scale matter distribution, with their clustering usually interpreted mainly as a function of halo mass. Yet, at fixed mass, their baryoni…
Galaxy Phase-Space and Field-Level Cosmology: The Strength of Semi-Analytic Models
Natalà S. M. de Santi, Natalí S. M. de Santi, Francisco Villaescusa-Navarro +11
Semi-analytic models are a widely used approach to simulate galaxy properties within a cosmological framework, relying on simplified yet physically motivated prescriptions. They ha…
Systematic bias in dark siren statistical methods and its impact on Hubble constant measurement
V. Alfradique, C. R. Bom, T. Castro
The advent of multimessenger cosmology, marked by the detection of GW170817, demonstrated that standard sirens are a valuable cosmological probe. In the absence of an electromagnet…
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…
