Dynamical friction in slab geometries and accretion discs / Vicente, Rodrigo (Lisbon, CENTRA) ; Cardoso, Vitor (Lisbon, CENTRA ; CERN) ; Zilhão, Miguel (Lisbon, CENTRA)
The evolution of planets, stars and even galaxies is driven, to a large extent, by dynamical friction of gravitational origin. There is now a good understanding of the friction produced by extended media, either collisionless of fluid-like. [...]

Parametrized black hole quasinormal ringdown. II. Coupled equations and quadratic corrections for nonrotating black holes / McManus, Ryan (Johns Hopkins U.) ; Berti, Emanuele (Johns Hopkins U.) ; Macedo, Caio F.B. (Para U.) ; Kimura, Masashi (Rikkyo U.) ; Maselli, Andrea (Rome U. ; INFN, Rome) ; Cardoso, Vitor (Lisbon, CENTRA ; CERN)
Linear perturbations of spherically symmetric spacetimes in general relativity are described by radial wave equations, with potentials that depend on the spin of the perturbing field. In previous work we studied the quasinormal mode spectrum of spacetimes for which the radial potentials are slightly modified from their general relativistic form, writing generic small modifications as a power-series expansion in the radial coordinate. [...]

Parametrized black hole quasinormal ringdown: Decoupled equations for nonrotating black holes / Cardoso, Vitor (IST, Lisbon (main) ; CERN) ; Kimura, Masashi (IST, Lisbon (main) ; Rikkyo U.) ; Maselli, Andrea (U. Rome La Sapienza (main) ; INFN, Rome) ; Berti, Emanuele (Johns Hopkins U. (main)) ; Macedo, Caio F.B. (Para U.) ; McManus, Ryan (Johns Hopkins U. (main))
Black hole solutions in general relativity are simple. The frequency spectrum of linear perturbations around these solutions (i.e., the quasinormal modes) is also simple, and therefore it is a prime target for fundamental tests of black hole spacetimes and of the underlying theory of gravity. [...]

Distinguishing black holes from horizonless objects through the excitation of resonances during inspiral / Cardoso, Vitor (CERN ; Lisbon, CENTRA) ; del Rio, Adrian (Lisbon, CENTRA) ; Kimura, Masashi (Rikkyo U.)
How well is the vacuum Kerr geometry a good description of the dark, compact objects in our universe? Precision measurements of accreting matter in the deep infrared and gravitational-wave measurements of coalescing objects are finally providing answers to this question. Here, we study the possibility of resonant excitation of the modes of the central object -- taken to be very compact but horizonless -- during an extreme-mass-ratio inspiral. [...]

Moving black holes: energy extraction, absorption cross-section and the ring of fire / Cardoso, Vitor (Lisbon, CENTRA ; CERN) ; Vicente, Rodrigo (Lisbon, CENTRA)
We consider the interaction between a plane wave and a (counter-moving) black hole. We show that energy is transferred from the black hole to the wave, giving rise to a negative absorption cross-section. [...]

Black holes are the simplest macroscopic objects, and provide unique tests of General Relativity. They have been compared to the Hydrogen atom in quantum mechanics. [...]

Testing the nature of dark compact objects: a status report / Cardoso, Vitor (Lisbon U. ; CERN) ; Pani, Paolo (Rome U. ; INFN, Rome)
Very compact objects probe extreme gravitational fields and may be the key to understand outstanding puzzles in fundamental physics. These include the nature of dark matter, the fate of spacetime singularities, or the loss of unitarity in Hawking evaporation. [...]
