Schwarzschild Black Holes and Propagation of Electromagnetic and Gravitational Waves. *
Disturbing of a spacetime geometry may result in the appearance of an oscillating and damped radiation the so-called quasinormal modes. Their periods of oscillations and damping coefficients carry unique information about the mass and the angular momentum, that would allow one to identify the source of the gravitational field. In this talk we present recent bounds on the diffused energy, applic...
متن کاملScattering by Black Holes
Black holes, objects so compact that not even light can escape their gravitational pull, are among the most intriguing concepts of modern science. As Kip Thorne wrote in 1974: “Of all the conceptions of the human mind from unicorns to gargoyles to the hydrogen bomb perhaps the most fantastic is the black hole: a hole in space with a definite edge over which anything can fall and nothing can esc...
متن کاملGeometrodynamics of Schwarzschild black holes.
The curvature coordinates T, R of a Schwarzschild spacetime are turned into canonical coordinates T (r),R(r) on the phase space of spherically symmetric black holes. The entire dynamical content of the Hamiltonian theory is reduced to the constraints requiring that the momenta PT (r), PR(r) vanish. What remains is a conjugate pair of canonical variables m and p whose values are the same on ever...
متن کاملFermion Scattering by a Schwarzschild Black Hole
Abstract We study the scattering of massive spin-half waves by a Schwarzschild black hole using analytical and numerical methods. We begin by extending a recent perturbation theory calculation to next order to obtain Born series for the differential cross section and Mott polarization, valid at small couplings. We continue by deriving an approximation for glory scattering of massive spinor part...
متن کاملRelating Schwarzschild Black Holes to Branes-Antibranes
We construct in the supergravity framework a relation between thermal chargeless nonextremal black three-branes and thermal Dirichlet branes-antibranes systems. We propose this relation as a possible explanation for the intriguing similarity between the black branes BekensteinHawking entropy and the field theory entropy of thermal branes-antibranes. We comment on various relations between brane...
