About Me

Hi! I am Borja, a postdoc researcher in Astrophysics, currently employed at the Osservatorio Astronomico di Roma - Istituto Nazionale di Astrofisica (Italy). My reserach interests mainly focus on galaxy evolution, with particular emphasis on constraining chemical enrichment, both observationally and theoretically.

Galaxies: Abundances

Beyond the [OIII]4363 auroral line: [NeIII]3868 as a direct tracer of the electron temperature

Alternative technique to derive physical properties in the photoionized ISM to extend both local and high-z studies.

Galaxies: Abundances

Chemical enrichment in LINERs from MaNGA: II. Characterizing the shape of the radial metallicity gradients

The AGN feed(back) process alters the shape of radial metallicity gradients depending on how evolved the galaxy is, and which is the dominant source for gas kinematics.

Galaxies: Abundances

A departure from the mass-metallicity relation in merging galaxies due to an infall of metal-poor gas

Mergen-driven infall of metal-poor gas causes metallicity dillutation but enhances star formation, explaining observed properties of (U)LIRGs.
