Absorption by stringy black holes
Sérgio Vinicius M. C. B. Xavier, Carolina L. Benone, Luís C. B. Crispino
We investigate the absorption of planar massless scalar waves by a charged rotating stringy black hole, namely a Kerr--Sen black hole. We compute numerically the absorption cross s…
Acoustic clouds: standing sound waves around a black hole analogue
Carolina L. Benone, Luis C. B. Crispino, Carlos Herdeiro +1
Under certain conditions sound waves in fluids experience an acoustic horizon with analogue properties to those of a black hole event horizon. In particular, a draining bathtub-lik…
Kerr-Newman scalar clouds
Carolina L. Benone, Luis C. B. Crispino, Carlos Herdeiro +1
Massive complex scalar fields can form bound states around Kerr black holes. These bound states -- dubbed scalar clouds -- are generically non-zero and finite on and outside the ho…
Absorption of a massive scalar field by a charged black hole
Carolina L. Benone, Ednilton S. de Oliveira, Sam R. Dolan +1
We calculate the absorption cross section of a massive neutral scalar field impinging upon a Reissner-Nordström black hole. First, we derive key approximations in the high- and low…
