Chemical signatures of formation processes in the stellar populations of simulated galaxies
(Oxford University Press, 2012-02)
We study the chemical properties of the stellar populations in eight simulations of the formation of Milky Way mass galaxies in a cold dark matter universe. Our simulations include metaldependent cooling and an explicitly ...
Dark matter response to galaxy formation
(Wiley Blackwell Publishing, Inc, 2010-08)
We have resimulated the six galaxy-sized haloes of the Aquarius Project including metaldependent cooling, star formation and supernova feedback. This allows us to study not only how dark matter haloes respond to galaxy ...
On the dynamical origin of the ICM metallicity evolution
(Wiley Blackwell Publishing, Inc, 2008-12)
We present a study on the origin of the metallicity evolution of the intra-cluster medium (ICM) by applying a semi-analytic model of galaxy formation to N-body/smoothed particle hydrodynamic (SPH) non-radiative numerical ...
On the mass assembly of low-mass galaxies in hydrodynamical simulations of structure formation
(Wiley-blackwell Publishing, Inc, 2013-11)
A population of galaxies is simulated in a cosmological box in order to analyse generic trends for the stellar, baryonic and halo mass assembly of low-mass galax- ies (M∗ 3 × 1010M⊙) as a function of their present halo ...
Exploring the role of cosmological shock waves in the Dianoga simulations of galaxy clusters
(Wiley Blackwell Publishing, Inc, 2021-11)
Cosmological shock waves are ubiquitous to cosmic structure formation and evolution. As a consequence, they play a major role in the energy distribution and thermalization of the intergalactic medium (IGM). We analyze the ...
Properties of the circumgalactic medium in simulations compared to observations
(EDP Sciences, 2018-01)
Context. Galaxies are surrounded by extended gaseous halos that store significant fractions of chemical elements. These are syntethized by the stellar populations and later ejected into the circumgalactic medium (CGM) by ...
Observaciones de moléculas deuteradas = Observations of deuterated molecules.
(Universidad de Concepción.Facultad de Ciencias Físicas y MatemáticasDepartamento de Astronomía., 2021)
The study of stars has been a relevant field for the scientific community for several decades, and
these days is still an active field of study because of the important effect of stars into their galactic
ecosystem. The ...
Field spheroid-dominated galaxies in a Λ-CDM Universe
(EDP Sciences, 2018)
Context. Understanding the formation and evolution of early-type, spheroid-dominated galaxies is an open question within the context of the hierarchical clustering scenario, particularly in low-density environments. Aims. ...
Semi-analytic galaxies-I. synthesis of environmental and star-forming regulation mechanisms
(Wiley Blackwell Publishing, Inc, 2018-09)
We present results from the semi-analytic model of galaxy formation SAG applied on the MULTIDARK simulation MDPL2. SAG features an updated supernova (SN) feedback scheme and a robust modelling of the environmental effects ...

(Wiley Blackwell Publishing, Inc, 2018-09)
We present results from the semi-analytic model of galaxy formation SAG applied on the MULTIDARK simulation MDPL2. SAG features an updated supernova (SN) feedback scheme and a robust modelling of the environmental effects ...
