La constante de Hubble (H0) es un parámetro crítico en cosmología que define propiedades esenciales del universo, como su tamaño, edad, tasa de expansión y...

Dwarf elliptical galaxies (dEs) are the most common galaxy class in dense environments, outnumbering all other classes combined. Their low masses make them...

Much of current astrophysical research is aimed at addressing one key issue: how galaxies form and evolve. We still do not fully understand the evolutionary...

One of the main challenges for current cosmology is the conciliation, in a single theory, of the formation of large-scale structures in the Universe and the...

Este trabajo está centrado en el estudio de los brotes de formación estelar (FE) de una muestra de Galaxias Enanas Compactas Azules (BCDs), la interacción de...

Las Galaxias Compactas Azules (BCGs) son objetos caracterizados por evidenciar intensos brotes de formación estelar que dominan gran parte de la luz que...

This thesis comprises of a full search in our galaxy for the hidden population of massive stars using the near-infrared photometry with a novel method and a...

Quasars are considered to be the most luminous subclass among Active Galactic Nuclei. Although they appear to be distributed everywhere in the Universe, only a...

In this thesis we study the effect that minor mergers have on the evolution of galaxies. We focus on three topics: the size evolution of massive elliptical...
