Galaxies are arguably complex systems. However, they also display many scaling relations between their physical properties, hinting that it might be possible to...

Vimos Public Extragalactic Redshift Survey (VIPERS) is a spectroscopic survey designed to investigate the spatial distribution of ~90k galaxies on redshift 0.4...

Stars, the most fundamental building blocks of galaxies, are born within the clouds of gas and dust and and during their lives they enrich the gas and the...

There are galaxies that remain untouched since the ancient Universe. These unique objects, the so-called relic galaxies, are several times more massive than our...

Spectroscopic analysis of stellar populations is widely used to understand the history of many systems including globular clusters, nuclear star clusters, dwarf...

The ultra-deep multiwavelength HST Frontier Fields coverage of the Abell Cluster 2744 is used to derive the stellar population properties of its intra-cluster...

(1) Stellar magnetic fields. Spectro-polarimetry is a very powerful tool to diagnose magnetic fields in a large variety of astrophysical objects. My research...

Nowadays, it is widely accepted that most galaxies undergo an active phase in their evolution. The impact of the energy released by active galactic nuclei (AGN)...

The formation and evolution of early-type galaxies constitutes a long-standing and crucial problem in cosmology. In all hierarchical clustering models within a...
