Robust marginalization of baryonic effects for cosmological inference at the field level

Francisco Villaescusa-Navarro, Shy Genel, Daniel Angles-Alcazar +11

We train neural networks to perform likelihood-free inference from 2D maps containing the total mass surface density from thousands of hydrodynamic simula…

Multifield Cosmology with Artificial Intelligence

Francisco Villaescusa-Navarro, Daniel Anglés-Alcázar, Shy Genel +10

Astrophysical processes such as feedback from supernovae and active galactic nuclei modify the properties and spatial distribution of dark matter, gas, and galaxies in a poorly und…

Can small-scale baryon inhomogeneities resolve the Hubble tension? An investigation with ACT DR4

Leander Thiele, Yilun Guan, J. Colin Hill +2

Small-scale inhomogeneities in the baryon density around recombination have been proposed as a solution to the tension between local and global determinations of the Hubble constan…

Accurate Analytic Model for the Weak Lensing Convergence One-Point Probability Distribution Function and its Auto-Covariance

Leander Thiele, J. Colin Hill, Kendrick M. Smith

The one-point probability distribution function (PDF) is a powerful summary statistic for non-Gaussian cosmological fields, such as the weak lensing (WL) convergence reconstructed…

Teaching neural networks to generate Fast Sunyaev Zel'dovich Maps

Leander Thiele, Francisco Villaescusa-Navarro, David N. Spergel +2

The thermal Sunyaev-Zel'dovich (tSZ) and the kinematic Sunyaev-Zel'dovich (kSZ) effects trace the distribution of electron pressure and momentum in the hot Universe. These observab…

Massive vector fields in Kerr--Newman and Kerr--Sen black hole spacetimes

Ramiro Cayuso, Oscar J. C. Dias, Finnian Gray +5

The superradiant instability modes of ultralight massive vector bosons are studied for weakly charged rotating black holes in Einstein--Maxwell gravity (the Kerr--Newman solution)…
