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 properties, 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 addressed 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.
