I am a theoretical astrophysicist from La Plata, Argentina, with an interest in the most energetic phenomena in the Universe, in particular, those occurring in the vicinity of black holes and neutron stars. When I was a child, I used to stay long hours at night looking at the stars with my father and our binoculars, and since then, I have always wanted to be an astronomer. I was lucky that I live close to the National University of La Plata, one of the only three Institutions that teach Astronomy in Argentina. I started my undergraduate studies in 2011, and I graduated in 2017 with a Master thesis about the potential effects of primordial black holes in the early cosmic evolution. In 2022, I obtained my PhD degree under the supervision of Prof. Gustavo E. Romero with a thesis on radiation from accreting black holes. I am currently a Postdoctoral Fellow at the Institute for Gravitation and the Cosmos at the Pennsylvania State University, where I work in Prof. David Radice's group on simulating the merging of neutron stars and investigating the high-energy emission that is produced after these events.

I am passionate about black holes and compact objects in general. My research interests involve several aspects of these intriguing objects and their relationships with their closest environment. Black holes on their own are unique predictions of Einstein's General Relativity Theory: compact regions where the spacetime is so distorted that once an object crosses a boundary, the event horizon, no matter how fast it moves, will never be able to escape back to the exterior. We also know that black holes are not isolated and sometimes they end up orbiting around another black hole. When this happens, their orbital motion distorts the spacetime producing gravitational waves, at the expense of the orbital energy of the binary system; the black holes finally merge in one of the most energetic processes known in the Universe. Moreover, when black holes are fed with matter, a very likely situation, an accretion disk forms and large amounts of energy are released in the form of several particles. The most extreme phenomena in our Universe correspond to this scenario: Active Galactic Nuclei (AGNs), Micro-quasars (MCQs), and Gamma-Ray Bursts (GRBs). My work tries to understand some of these phenomena that occur in the vicinity of accreting black holes.
In particular, I am working on the following sub-topics:
How can we identify the presence of two supermassive black holes orbiting each other through electromagnetic emission? What are the specific electromagnetic signatures one could expect to observe from these systems? If the black holes produce relativistic jets, how do they interact between themselves?
What happens when two neutron stars merge? How do magnetic fields evolve? What are the main multimessenger signals from these events?
What role do nonthermal particles play in hot accretion flows? How do they influence the immediate vicinity of accreting black holes?
Which properties of relativistic jets can we infer via detailed broadband SED modelling?
