Wave optical imaging of an oscillating electric dipole orbiting a black hole
Filipe Nazaré, João S. Santos, Vitor Cardoso +1
We study the electromagnetic radiation and wave-optical imaging of an oscillating electric dipole orbiting a Kerr black hole. We derive the effective 4-current associated with a po…
Resonances in binary extreme mass ratio inspirals
João S. Santos, Vitor Cardoso, Alexandru Lupsasca +2
Stellar-mass binaries evolving in the vicinity of supermassive black holes (SMBHs) may be common in the universe, either in active galactic nuclei or in other astrophysical environ…
Gravitational waves from b-EMRIs: Doppler shift and beaming, resonant excitation, helicity oscillations and self-lensing
João S. Santos, Vitor Cardoso, José Natário +1
We study gravitational waves from a stellar-mass binary orbiting a spinning supermassive black hole, a system referred to as a binary extreme mass ratio inspiral (b-EMRI). We use D…
An exact solution describing a scalar counterpart to the Schwarzschild-Melvin Universe
Vitor Cardoso, José Natário
The Schwarzschild-Melvin spacetime is an exact solution of the Einstein electrovacuum equations describing a black hole immersed in a magnetic field which is asymptotically aligned…
Floating orbits and energy extraction from magnetized Kerr black holes
João S. Santos, Vítor Cardoso, José Natário
We study electromagnetic radiation reaction on a charged particle around a weakly magnetized Kerr black hole. We solve numerically the Teukolsky equation to find energy fluxes in e…
