I am an astrophysicist and currently a Ph.D. student in Astrophysics. I’m particularly interested in understanding the role of Black Holes in the Universe. How can these invisible entities affect their host galaxy? And how their fate is bound to the future of the larger structures.

I work in the IAG Black Hole group under the orientation of the Prof Rodrigo Nemmen. My current research project is to perform numerical hydrodynamical and magnetohydrodynamical simulations of accretion flows around black holes. My goal is to understand how supermassive black holes in the center of galaxies accrete matter and the implications of the accretion process. AGN winds and feedback and their consequences are my current research topic.

I work with analysis and modeling of multiwavelength observations of galactic nuclei too. The objective is to understand the physical processes that are occurring in the AGNs and compare real data with simulations. I am interested in machine learning methods to model AGN observable emission.

Research Interests

  • The physics behind accretion flows around compact objects, mainly black holes;
  • Numerical simulations of accretion flow around black holes;
  • The interaction between the accretion disk of a supermassive black hole and its host galaxy. Consequences of winds and feedback.
