Where the Forest Goes Dark: Halo-centered Characterization of High Column Density Systems with IllustrisTNG
Victor R. Soares da Silva, Daniel López-Cano, L. Raul Abramo +2
High column density systems of neutral hydrogen (HCDs) --- Lyman limit systems (LLSs), sub-damped and damped Ly absorbers (DLAs) --- contaminate both the 3D and the 1D statistic…
Evaluating the flexibility of the MillenniumTNG galaxy formation model with multi-zoom re-simulations
Francisco Maion, Raul E. Angulo, Volker Springel +2
In this study we introduce a new simulation campaign designed to understand how parameters that control star-formation and AGN feedback processes in cosmological hydrodynamical sim…
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…
Probabilistic Estimators of Lagrangian Shape Biases: Universal Relations and Physical Insights
Francisco Maion, Jens Stücker, Raul E. Angulo
The intrinsic alignment of galaxies is a key factor in modeling weak-lensing observations and can serve as a valuable signal for both cosmological and astrophysical studies. Modell…
Probabilistic Lagrangian bias estimators and the cumulant bias expansion
Jens Stücker, Marcos Pellejero-Ibáñez, Raul E. Angulo +2
The spatial distribution of galaxies is a highly complex phenomenon currently impossible to predict deterministically. However, by using a statistical relation, it…
HYMALAIA: A Hybrid Lagrangian Model for Intrinsic Alignments
Francisco Maion, Raul E. Angulo, Thomas Bakx +3
The intrinsic alignment of galaxies is an important ingredient for modelling weak-lensing measurements, and a potentially valuable cosmological and astrophysical signal. In this pa…
Suppressing variance in 21-cm signal simulations during reionization
Sambit K. Giri, Aurel Schneider, Francisco Maion +1
Current best limits on the 21-cm signal during reionization are provided at large scales (100 Mpc). To model these scales, enormous simulation volumes are required which a…
The Bacco Simulation Project: Bacco Hybrid Lagrangian Bias Expansion Model in Redshift Space
Marcos Pellejero-Ibanez, Raul E. Angulo, Matteo Zennaro +4
We present an emulator that accurately predicts the power spectrum of galaxies in redshift space as a function of cosmological parameters. Our emulator is based on a 2nd-order Lagr…
Statistics of biased tracers in variance-suppressed simulations
Francisco Maion, Raul E. Angulo, Matteo Zennaro
Cosmological simulations play an increasingly important role in analysing the observed large-scale structure of the Universe. Recently, they have been particularly important in bui…
Priors on Lagrangian bias parameters from galaxy formation modelling
Matteo Zennaro, Raul E. Angulo, Sergio Contreras +2
We study the relations among the parameters of the hybrid Lagrangian bias expansion model, fitting biased auto and cross power spectra up to $k_{\rm max} = 0.7 \, h \, \mathrm{Mpc}…
