I finished the degree in Physics in the Universidad Autónoma de Madrid in 2018. In that same university, in 2019, I got the Master in Theoretical Physics in the modality of Astrophyiscs and Cosmology. I started working in my pHD at CAB-INTA in february 2020. It is titled

“Star formation timescales in the assembly of massive galaxies: search for the earliest progenitors in the first 5 Gyr of the Universe history”.

Along the PhD, we will study the formation and evolution of the most massive galaxies of our surroundings, those with masses similar or higher than the Milky Way one, focusing on the first evolutionary phases that took place during the first third of life of the Universe (z>1.3). The main objective is to determine the temporal scale of the star formation in massive galaxies.

Our data come from SHARDS+, the only legacy program being carried out by the GTC telescope. Using these data, in combination with leading observations from other observatories such as the Hubble, Spitzer, Herschel, ALMA, VLT or Keck observatories, we will look for young massive galaxies (through their Lyman-alpha emission) and old massive galaxies at high redshifts. Later on, we will analyze the spectral energy distributions of these objects in order to characterize their stellar populations and determine their star formation histories.
