About me

I am an extragalactic astronomer working at the Universidad de La Laguna and the Instituto de Astrofísica de Canarias.

My main scientific interest is the study of nearby galaxies to try to figure out what their evolution has been (the so-called galactic archæology). I have worked in rings of star formation and also in the thick discs of edge-on galaxies.

I am leading the Archæology of Thick discs (ArcThick) collaboration. ArcThick gathers leading extragalactic astronomers with the aim of studying the formation and evolution of thick discs using imaging, spectroscopy, and modelling. Thick discs are a key feature to understand how galaxies themselves form and evolve.

About the header Image

An NGC 522 image made with data from the Spitzer Survey of Stellar Structure in Galaxies (S4G). The image was produced by adding the 3.6 μm and 4.5 μm bands of the survey. This almost perfectly edge-on galaxy shows a boxy-shaped bulge and a warp. The small influence of dust in the mid-infrared and the great depth of the image allows us to easily study the thick and thin disc components of NGC 522.
