On the origin of the evolution of the halo occupation distribution
Sergio Contreras, Idit Zehavi
We use the TNG300 magneto-hydrodynamic simulation and mock catalogues built using subhalo abundance matching (SHAM) to study the origin of the redshift evolution of the halo occupa…
Consistent clustering and lensing of SDSS-III BOSS galaxies with an extended abundance matching formalism
Sergio Contreras, Jonás Chaves-Montero, Raul E. Angulo
Several analyses have shown that LCDM-based models cannot jointly describe the clustering (GC) and galaxy-galaxy lensing (GGL) of galaxies in the SDSS-III BOSS survey, which is com…
DES Y3 cosmic shear down to small scales: constraints on cosmology and baryons
Giovanni Aricò, Raul E. Angulo, Matteo Zennaro +3
We present the first analysis of cosmic shear measured in DES Y3 that employs the entire range of angular scales in the data. To achieve this, we build upon recent advances in the…
Consistent and simultaneous modelling of galaxy clustering and galaxy-galaxy lensing with Subhalo Abundance Matching
Sergio Contreras, Raul E. Angulo, Jonás Chaves-Montero +2
The spatial distribution of galaxies and their gravitational lensing signal offer complementary tests of galaxy formation physics and cosmology. However, their synergy can only be…
The galaxy formation origin of the lensing is low problem
Jonas Chaves-Montero, Raul E. Angulo, Sergio Contreras
Recent analyses show that CDM-based models optimised to reproduce the clustering of massive galaxies overestimate their gravitational lensing by about 30\%, the so-called lensin…
The MillenniumTNG Project: An improved two-halo model for the galaxy-halo connection of red and blue galaxies
Boryana Hadzhiyska, Daniel Eisenstein, Lars Hernquist +11
Approximate methods to populate dark matter halos with galaxies are of great utility to large galaxy surveys. However, the limitations of simple halo occupation models (HODs) precl…
