The metallicity gradients of star-forming regions store information of the assembly history of galaxies ERIS adopts the hypothesis that chemical abundances store information on the main events that form galaxies. In this paper our master student, Francisco Jara,  together with members of our team, studied galaxies from the EAGLE project.  By studying the metal content […]

L3: Chemical Evolution Modeling

To understand the impact on phylogenetic trees regarding the role of the various chemicalelements, semi-analytical models of chemical evolution are analyzed. These models includeFlex-CE or L-Galaxies, which take into account the non-linear evolution of a structure in acosmological framework and introduce the physics of baryons by using a set of recipeswhose free parameters are chosen

L2: Cosmological Galaxy Formation Simulations

This research line aims to use computational simulations of galaxy evolution (such as [Patricia’s simulation] and L-Galaxies) to study the physical processes that occur throughout the life of galaxies, particularly focusing on the Milky Way. We are particularly interested in the chemical evolution of baryons as galaxies form, including enrichment processes from Type Ia &

L1: Stellar Spectral Analysis

We develop methods to determine chemical composition in stars. ERIS attributes the chemical abundances imprinted in stellar atmospheres as the heritable marker for the phylogenetic signal of galaxy evolution. The problem of determining stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity, etc), and subsequently determining individual chemical abundances, is complex. Despite the rapid development

ERIS en Australia 

To finish the year, In December 2022, ERIS members managed to meet in the last country where we’re based: Australia. We had the chance to mingle and work!  Paula Jofre, the ERIS director, travelled as part of the “Mt. Stromlo Distinguished visitor programme”, which invites researchers from abroad to visit the Australian National University (ANU).
