Breaking baryon-cosmology degeneracy with the electron density power spectrum

Andrina Nicola, Francisco Villaescusa-Navarro, David N. Spergel +8

Uncertain feedback processes in galaxies affect the distribution of matter, currently limiting the power of weak lensing surveys. If we can identify cosmological statistics that ar…

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…

The growth of density perturbations in the last 10 billion years from tomographic large-scale structure data

Carlos García-García, Jaime Ruiz Zapatero, David Alonso +5

In order to investigate the origin of the ongoing tension between the amplitude of matter fluctuations measured by weak lensing experiments at low redshifts and the value inferred…

Hefty enhancement of cosmological constraints from the DES Y1 data using a Hybrid Effective Field Theory approach to galaxy bias

Boryana Hadzhiyska, Carlos García-García, David Alonso +2

We present a re-analysis of cosmic shear and galaxy clustering from first-year Dark Energy Survey data (DES Y1), making use of a Hybrid Effective Field Theory (HEFT) approach to mo…
