Assembly bias in quadratic bias parameters of dark matter halos from forward modeling
Titouan Lazeyras, Alexandre Barreira, Fabian Schmidt
We use the forward modeling approach to galaxy clustering combined with the likelihood from the effective-field theory of large-scale structure to measure assembly bias, i.e. the d…
Galaxy bias from forward models: linear and second-order bias of IllustrisTNG galaxies
Alexandre Barreira, Titouan Lazeyras, Fabian Schmidt
We use field-level forward models of galaxy clustering and the EFT likelihood formalism to study, for the first time for self-consistently simulated galaxies, the relations between…
Quantifying the impact of baryon-CDM perturbations on halo clustering and baryon fraction
Hasti Khoraminezhad, Titouan Lazeyras, Raul E. Angulo +2
Baryons and cold dark matter (CDM) did not comove prior to recombination. This leads to differences in the local baryon and CDM densities, the so-called baryon-CDM isocurvature per…
The impact of massive neutrinos on halo assembly bias
Titouan Lazeyras, Francisco Villaescusa-Navarro, Matteo Viel
Using the publicly available Quijote simulations, we present the first measurements of the assembly bias of dark matter halos in N-body simulations which include massive neutrinos.…
