Extreme mass ratio head-on collisions of black holes in Einstein-scalar-Gauss-Bonnet theory
Antonia M. Frassino, David C. Lopes, Jorge V. Rocha
The evolution of the event horizon when two black holes merge can be determined by resorting to ray-tracing techniques on a single black hole spacetime, under the assumption that t…
Self-similar collapse with elasticity
Jorge V. Rocha, Diogo L. F. G. Silva
Critical collapse is a well-studied subject for a variety of self-gravitating matter. One of the most intensively examined models is that of perfect fluids, which have been used ex…
Weak Cosmic Censorship with spinning particles in Kerr-(A)dS spacetimes
Antonia M. Frassino, Jorge V. Rocha, Andrea P. Sanna
We investigate the weak cosmic censorship conjecture by analyzing the dynamics of spinning timelike particles dropped along the rotational axis of an extremal Kerr (anti)de Sitter…
Tidal Love numbers of static black holes in anti-de Sitter
Edgardo Franzin, Antonia M. Frassino, Jorge V. Rocha
Tidal Love numbers of anti-de Sitter black holes are understood as linear response coefficients governing how the holographically dual plasma polarizes when the geometry of the spa…
The impact of higher derivative corrections to General Relativity on black hole mergers
João M. Dias, Antonia M. Frassino, David C. Lopes +2
The merging of two black holes is a notoriously difficult process to describe exactly. Nevertheless, the hindrances posed by gravity's nonlinearity can be circumvented by focusing…
Weak cosmic censorship and the rotating quantum BTZ black hole
Antonia M. Frassino, Jorge V. Rocha, Andrea P. Sanna
Tests of the weak cosmic censorship conjecture examine the possibility of the breakdown of predictivity of the gravitational theory considered, by checking if curvature singulariti…
