Not Hydro: Using Neural Networks to estimate galaxy properties on a Dark-Matter-Only simulation
Cristian Hernández Cuevas, Roberto E. González, Nelson D. Padilla
Using data from TNG300-2, we train a neural network (NN) to recreate the stellar mass () and star formation rate (SFR) of central galaxies in a dark-matter-only simulation. We…
Active galactic nuclei and gravitational redshifts

Fingerprints of modified gravity on galaxies in voids
Pedro Cataldi, Susana Pedrosa, Nelson Padilla +3

A deep learning approach to halo merger tree construction
Sandra Robles, Jonathan S. Gómez, Adín Ramírez Rivera +2
A key ingredient for semi-analytic models (SAMs) of galaxy formation is the mass assembly history of haloes, encoded in a tree structure. The most commonly used method to construct…
Satellite galaxies in groups in the CIELO Project I. Gas removal from galaxies and its re-distribution in the intragroup medium
S. Rodríguez, D. Garcia Lambas, N. D. Padilla +5
We study the impact of the environment on galaxies as they fall in and orbit in the potential well of a Local Group (LG) analogue, following them with high cadence. The analysis is…
Revealing the properties of void galaxies and their assembly using the EAGLE simulation
Yetli Rosas-Guevara, Patricia Tissera, Claudia del P. Lagos +2

Jonathan S. Gómez, Nelson D. Padilla, John C. Helly +3
We examine the effect of using different halo finders and merger tree building algorithms on galaxy properties predicted using the GALFORM semi-analytical model run on a high resol…
Too dense to go through: The importance of low-mass clusters for satellite quenching
Diego Pallero, Facundo A. Gómez, Nelson D. Padilla +3
We study the evolution of satellite galaxies in clusters of the \textsc{c-eagle} simulations, a suite of 30 high-resolution cosmological hydrodynamical zoom-in simulations based on…

P. Troncoso-Iribarren, N. Padilla, C. Santander +4
We use the EAGLE simulations to study the effects of the intra-cluster medium (ICM) on the spatially resolved star-formation activity in galaxies. We study three cases of galaxy as…

S. Rodríguez, D. Garcia Lambas, N. D. Padilla +1
We analyse the presence of dust around galaxy group members through the reddening of background quasars. By taking into account quasar colour and their dependence on redshift and a…
