Astrophysics

During my M.Sc., I worked with Prof. Orfeu Bertolami on some of the astrophysical consequences of considering a non-minimal coupling between geometry and matter in Einstein’s theory of general relativity. We reported our findings here and, in greater detail, in my thesis (here).

Ever since then, I have tried to keep abreast of the developments in the (very vast) field of astrophysics.

More recently, I have started working with the group of Prof. Vitor Cardoso on the topic of dynamical friction in a gaseous medium.

Perturbation in the density of a gas caused by the orbital motion of two massive bodies in a binary system. The heterogeneous distribution of the gas density generates a net friction force on the bodies, which may cause the decay of their orbits. You can check a video of the temporal evolution of the density wake here.
