Research Interests
Mainly interested in extragalactic astronomy, so far I have focused on the study of galactic nuclei.
The central region of galaxies can be disentangled regarding nebular propreties, stellar populations, and the activity of the central supermassive black hole.
In my Master's, I proposed alternative diagnostic diagrams for the classification of galactic nuclei according to their dominant source of ionization, considering nearby SDSS galaxies and photoionization models produced with Starburst99 and CLOUDY.
In the PhD I started in Brazil, I was addressing issues of the first billions of years of the Universe, studying radio galaxies and quasars at high redshift with scheduled observations with JWST and HST.
In my current PhD in Germany, I am working with the comparison of spectroscopy in the optical domain (SDSS) and X-ray information (eROSITA) of active galactic nuclei in an all-sky survey.
