The local PNG bias of neutral Hydrogen,
Alexandre Barreira
We use separate universe simulations with the IllustrisTNG galaxy formation model to predict the local PNG bias parameters and of atomic neutral hydrogen, ${\rm H_I}…
Predictions for local PNG bias in the galaxy power spectrum and bispectrum and the consequences for constraints
Alexandre Barreira
We use hydrodynamical separate universe simulations with the IllustrisTNG model to predict the local primordial non-Gaussianity (PNG) bias parameters and , which ente…
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…
