Learning the Universe with cosmological rescaling of merger trees and semi-analytic galaxy formation models
Richard Stiskalek, Lucia A. Perez, Shy Genel +3
Learning cosmology from galaxy surveys requires large suites of simulations spanning the cosmological and astrophysical parameter space, yet hydrodynamical simulations of galaxy fo…
Validation of the Hybrid Bias Expansion model for the galaxy bispectrum
Marcos Pellejero Ibáñez, Marcos Pellejero Ibáñez, Raul E. Angulo +10
The Hybrid Bias Expansion model (also known as Hybrid Effective Field Theory, HEFT) provides a promising way to extend the range of validity of perturbative large-scale structure m…
The evolution of the baryonic content and mass profiles of satellite galaxies in the MTNG simulations
Sergio Contreras, Raul E. Angulo, Giovanni Aricò +5
Empirical models often rely on key relations from the galaxy--halo connection to construct mock galaxy catalogues. These relations typically describe central galaxies more accurate…
Cosmological constraints from the small scale clustering of Emission Line Galaxies
Sara Ortega-Martinez, Raul E. Angulo, Sergio Contreras +7
Spectroscopic surveys such as the Dark Energy Spectroscopic Instrument (DESI) and Euclid are mapping the spatial distribution of millions of galaxies, with Emission Line Galaxies (…
Cosmological constraints from galaxy clustering and galaxy-galaxy lensing with extended SubHalo Abundance Matching
Constance Mahony, Sergio Contreras, Raul E. Angulo +3
We present the first cosmological constraints from a joint analysis of galaxy clustering and galaxy-galaxy lensing using extended SubHalo Abundance Matching (SHAMe). We analyse ste…
The effect of baryons on the positions and velocities of satellite galaxies in the MTNG simulation
Sergio Contreras, Raul E. Angulo, Sownak Bose +5
Mock galaxy catalogues are often constructed from dark-matter-only simulations based on the galaxy-halo connection. Although modern mocks can reproduce galaxy clustering to some ex…
