Picture of Prof. Rodrigo Nemmen

I am an astrophysicist and my goal is to understand black holes and their impact on the universe. 

My research group — the Black Hole Group at University of Sao Paulo —works at the interface between theory and observations, quantifying how black holes interact with their surroundings, accreting matter, releasing radiation and accelerating particles into relativistic outflows which regulate the growth of their host galaxies. We are analysing a wide-range of multiwavelength observations of galactic nuclei—in particular gamma-rays—and using state-of-the-art numerical simulations of black hole accretion.

Research Interests

  • Black hole physics, accretion flows and jet formation
  • High-energy astrophysics, in particular gamma-ray astronomy
  • Astronomical objects: active galactic nuclei, stellar-mass black holes, co-evolution of blackholes and their host environments through feedback
  • High-performance computing and deep learning applied to interesting, tough problems

Curious about my research group, projects for students or open positions for postdoc?
