In this page, you can find all publications I was part of. They are divided among those in which I was part as «Main author» and those as «Co-author». In each case you will find the list of authors, links to the publications and, at least in those in which I had a major contribution, a visual abstract that sumarizes the study. If you have any question or want something else, please, contact me.

- My contribution: This article uses part of my M.Sc. thesis. In particular, I participated in the reduction from the GTC/EMIR spectra of epochs E–18A, E–18B, E–18C, E–18D, E–21A, E–21B, and E–21C. I also obtained, when possible, the K-band photometry from the EMIR acquisition images.
