Dark matter response to galaxy assembly history

Published in A&A, 2019

In this article, we study the properties of four Milky Way mass dark matter haloes from the Aquarius project during their assembly history, between z = 0−4.

Baryons shaping dark matter haloes

Published in MNRAS, 2020

In this work we aim at investigating the effects of baryons on the dark matter haloes structure, focusing on the correlation between the presence and importance of stellar discs and the halo shapes. We study the properties of a subsample of DM haloes from Fenix and eagle cosmological simulations.

Fingerprints of modified gravity on galaxies in voids

Published in MNRAS, 2022

In this work, we search for detectable signatures of f(R) gravity and its chameleon screening mechanism in the baryonic and dark matter properties of simulated void galaxies. The enhancement of the gravitational acceleration can have a meaningful impact on the scaling relations as well as on the halo morphology. The galaxy rotational velocity field (calculated with the velocity of the gas disc and the acceleration fields) deviates from the typical values of the Tully-Fisher Relation (TFR) in GR

Evolution of dark matter haloes in CIELO simulations

Published in BAAA64, 2023

This article analyze the dark matter (dm) halo evolution through time. For this study we use a Milky Way like haloes subsample from CIELO (ChemodynamIcal propertiEs of gaLaxies and the cOsmic web) project. This project aims at studying the formation of galaxies in different environments using zoom-ins simulations.

Redshift evolution of the dark matter haloes shapes

Published in MNRAS, 2023

In this work, we aim at investigating the morphology evolution of Milky Way mass-like dark matter haloes selected from the CIELO and IllustrisTNG Projects. The connection between halo shapes and their environment has been studied in previous works at z=0 but their connection remains yet to be fully understood. We focus on the evolution across cosmic time of the halo shapes and the relation with the infalling material, using hydrodynamical simulations

The CIELO Project: The Chemo-dynamical properties of gaLaxies and the cosmic web

Published in (submitted to A&A), 2025

The CIELO project introduces a novel set of chemo-dynamical zoom-in simulations, designed to simultaneously resolve galaxies and their nearby environments.
