Machine Learning applications to Galaxy Clusters
Gustavo Yepes, Daniel de Andrés
This chapter reviews the application of Artificial Intelligence (AI) techniques to the study of galaxy clusters, covering both theoretical developments and their use as tools to in…
Euclid preparation. Simulated galaxy catalogues for non-standard cosmological models
Euclid Collaboration, M. -A. Breton, P. Fosalba +289
Stage-IV galaxy surveys will provide the opportunity to test cosmological models and the underlying theory of gravity with unparalleled precision. In this context, it is crucial fo…
A hydrodynamical CLONE of the Virgo cluster: II. Confronting observed and synthetic galaxy population twins in a dense environment
Jenny G. Sorce, Sean L. McGee, Yohan Dubois +3
Galaxy clusters offer powerful laboratories for studying galaxy evolution in dense environments. In this context, the Constrained LOcal and Nesting Environment (CLONE) project prov…
Accurate -body simulations with local Primordial non-Gaussianities: initial conditions and aliasing
Adrian G. Adame, Santiago Avila, Violeta Gonzalez-Perez +3
New generation galaxy surveys targeting constraints on local primordial non-Gaussianity (PNG) demand -body simulations that accurately reproduce its effects. In this work, we ex…
The multi-dimensional halo assembly bias can be preserved when enhancing halo properties with HALOSCOPE
Sujatha Ramakrishnan, Violeta Gonzalez-Perez, Gabriele Parimbelli +1
Over \% of dark matter haloes in cosmological simulations have unresolved properties. This can hinder the dynamical range of simulations and result in systematic biases when mo…
An improved Halo Occupation Distribution prescription from UNITsim H_alpha Emission Line Galaxies: conformity and modified radial profile
Guillermo Reyes-Peraza, Santiago Avila, Violeta Gonzalez-Perez +4
Emission line galaxies (ELGs) are targeted by the new generation of spectroscopic surveys to make unprecedented measurements in cosmology from their distribution. Accurately interp…
PNG-UNITsims: Halo clustering response to primordial non-Gaussianities as a function of mass
Adrian G. Adame, Santiago Avila, Violeta Gonzalez-Perez +7
We present the largest full N-body simulation to date with local primordial non-Gaussianities (L-PNG), the \textsc{PNG-UNITsim}. It tracks the evolution of particles withi…
Improving and extending non-Poissonian distributions for satellite galaxies sampling in HOD: applications to eBOSS ELGs
Bernhard Vos-Ginés, Santiago Avila, Violeta Gonzalez-Perez +1
Halo Occupation Distribution (HOD) models help us to connect observations and theory, by assigning galaxies to dark matter haloes. In this work we study one of the components of HO…
