My name is Felipe Goicovic, and I am currently a postdoctoral researcher at the Institute for Theoretical Astrophysics (ITA), located in Heidelberg, Germany. It is important to mention that, even though my "official" last name is Garrido, I have been using my second surname, Goicovic (from my mother's side) for academic propuses. Yes, in Chile we have 2 surnames.
I finished my doctoral studies in Astrophysics with a double degree from the Pontificia Universidad Católica de Chile (PUC) and University of Heidelberg. Since September of 2018, I am a postdoc at the Planet Formation Group at ITA, which is led by Prof. Cornelis Dullemond.
My main research interest can be summarized as the study of gas dynamics and accretion around compact objects, mainly using numerical simulations.
Since we know that most galaxies contain supermassive black holes in their centre, the formation of binaries of these objects is unavoidable during the evolution of galaxies by subsequent mergers. Because of the complexity of the interactions with the ambient medium, together with the huge dynamical range that black holes must traverse in their way to coalescence, numerical simulations are essential to understang the different stages of the evolution. I model the formation and dynamics of the gaseous discs around the binaries, calculate how their orbits are modified by the gas presence, and predict observational signatures.
A tidal disruption event occurs when a star gets sufficiently close to a supermassive black hole and is pulled apart by the tidal forces. It has been proposed the appearance of flares produced by these events, and the posterior decay of the light curve are sensitive to whether the star is partially or totally destroyed by the tidal field, but the physics of the disruption and later fall-back of the debris are still poorly understood. I use numerical simulations to model the destruction and subsequent evolution of stars as they approach a supermassive black hole with the aim of producing realistic light-curves, as well as predict the fate of the stellar remnants.
During the early stages of star formation, the collapsing gas with higher angular momentum will quickly flatten into a disc surrounding the protostar. Because these discs usually contain solids that collide and aggregate through time, they become the eventual birthplace of planetary systems, such as our own Solar System. Using numerical techniques, I study the formation and dynamics of these protoplanetary discs, as well as the accretion of solids during the bluild up of (proto)planets.
