Strong-Field Gravitational-Wave Lensing from Ray-Traced Arrival-Time Surfaces
Luka Vujeva, João S. Santos, Brian C. Seymour
The diffraction integral formalism has been greatly successful in describing gravitational wave lensing effects in scenarios where the wavelength of the signal is comparable to the…
Strong Field Gravitational Lensing in Full Wave Optics
João Sieiro dos Santos, Luka Vujeva
Compact binaries evolving in the vicinity of massive black holes may be commonplace in the Universe, and their gravitational waves carry signatures of their environment. We study t…
Ringdown and lensing of triple systems
Vitor Cardoso, Giuseppe Ficarra, Jaime Redondo-Yuste +1
Triple systems have progressively been recognized as ubiquitous in our Universe and provide a good testing ground for wave generation and propagation in nontrivial environments. We…
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…
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…
Radiation reaction in weakly magnetized black holes: can the tail term be ignored in the strong field regime?
João S. Santos, Vitor Cardoso, José Natário
We study radiation from charged particles in circular motion around a Schwarzschild black hole immersed in an asymptotically uniform magnetic field. In curved space, the radiation…
Electromagnetic radiation reaction and energy extraction from black holes: The tail term cannot be ignored
João S. Santos, Vitor Cardoso, José Natário
We study electromagnetic radiation reaction in curved space and the dynamics of radiating charged particles. The equation of motion for such particles is the DeWitt-Brehme equation…
Hydrodynamic electrons in Graphene: a viscous boundary-layer description
Pedro Cosme, João S. Santos, Hugo Terças
In this paper we dwell over the study of the boundary layer problem in a hydrodynamical description of the electrons in gated graphene. It has been verified experimentally that thi…
