Tracing Galaxy Bias Through the Cosmic Web: The Role of Filaments
Constanza A. Soto-Suárez, Antonio D. Montero-Dorta, Daniela Galárraga-Espinosa +4
The large-scale clustering of galaxies depends not only on their internal properties but also on their location within the cosmic web, which defines the anisotropic environments wh…
Predicting galaxy bias using machine learning
Catalina Riveros-Jara, Antonio D. Montero-Dorta, Natália V. N. Rodrigues +6
Understanding how galaxies trace the underlying matter density field is essential for characterizing the influence of the large-scale structure on galaxy formation, being therefore…
The Galaxy Bias Profile of Cosmic Voids:A Comparison of Void Finders
Ignacio G. Alfaro, Antonio D. Montero-Dorta, Jorge F. Bustillos +6
Cosmic voids, the largest underdense regions in the Universe, provide unique laboratories for studying galaxy formation and constitute powerful probes of cosmology. Recent work has…
The galaxy bias profile of cosmic voids
Antonio D. Montero-Dorta, Andrés Balaguera-Antolínez, Ignacio G. Alfaro +7
Cosmic voids are underdense regions within the large-scale structure of the Universe, spanning a wide range of physical scales - from a few megaparsecs (Mpc) to the largest observa…
Individual halo bias in models of gravity
Jorge Enrique García-Farieta, Antonio D. Montero-Dorta, Andrés Balaguera-Antolínez
Halo bias links the statistical properties of the spatial distribution of dark matter halos to those of the underlying dark matter field, providing insights into clustering propert…
Fast simulation mapping: from standard to modified gravity cosmologies using the bias assignment method
Jorge Enrique García-Farieta, Andrés Balaguera-Antolínez, Francisco-Shu Kitaura
We assess the effectiveness of a non-parametric bias model in generating mock halo catalogues for modified gravity (MG) cosmologies, relying on the distribution of dark matter from…
Secondary halo bias through cosmic time I: Scaling relations and the connection with the cosmic web
Andrés Balaguera-Antolínez, Antonio D. Montero-Dorta, Ginevra Favole
We measure the signal of secondary halo bias as a function of a variety of intrinsic and environmental halo properties, and characterize its statistical significance as a function…
Field-level Lyman-alpha forest modelling in redshift space via augmented non-local Fluctuating Gunn-Peterson Approximation
Francesco Sinigaglia, Francisco-Shu Kitaura, Kentaro Nagamine +2
We present an improved analytical model to predict the Lyman-alpha forest at the field level in redshift space from the dark matter field, expanding upon the widely-used Fluctuatin…
The Cosmic Web from Perturbation Theory
F. -S. Kitaura, F. Sinigaglia, A. Balaguera-Antolínez +1
Context: Analyzing the large-scale structure (LSS) with galaxy surveys demands accurate structure formation models. Such models should ideally be fast and have a clear theoretical…
DESI Mock Challenge: Halo and galaxy catalogs with the bias assignment method
Andrés Balaguera-Antolínez, Francisco-Shu Kitaura, Shadab Alam +16
We present a novel approach to the construction of mock galaxy catalogues for large-scale structure analysis based on the distribution of dark matter halos obtained with effective…
The bias from hydrodynamic simulations: mapping baryon physics onto dark matter fields
Francesco Sinigaglia, Francisco-Shu Kitaura, Andrés Balaguera-Antolínez +4
This paper investigates the hierarchy of baryon physics assembly bias relations obtained from state-of-the-art hydrodynamic simulations with respect to the underlying cosmic web sp…
The cosmic web connection to the dark matter halo distribution through gravity
Francisco-Shu Kitaura, Andrés Balaguera-Antolínez, Francesco Sinigaglia +1
This work investigates the connection between the cosmic web and the halo distribution through the gravitational potential at the field level. We combine three fields of research,…
One simulation to have them all: performance of the Bias Assignment Method against N-body simulations
Andrés Balaguera-Antolínez, Francisco-Shu Kitaura, Marcos Pellejero-Ibáñez +6
In this paper we demonstrate that the information encoded in \emph{one} single (sufficiently large) -body simulation can be used to reproduce arbitrary numbers of halo catalogue…
