Test fields cannot destroy extremal de Sitter black holes
Jose Natario, Rodrigo Vicente
We determine the timelike Killing vector field that gives the correct definition of energy for test fields propagating in a Kerr-Newman-de Sitter spacetime, and use this result to…

Moving black holes: energy extraction, absorption cross-section and the ring of fire
Vitor Cardoso, Rodrigo Vicente
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 ab…

Dynamical friction in slab geometries and accretion disks
Rodrigo Vicente, Vitor Cardoso, Miguel Zilhão
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 pro…
