Newtonian vs black - hole scattering ∗
نویسنده
چکیده
We discuss non-relativistic scattering by a Newtonian potential. We show that the gray-body factors associated with scattering by a black hole exhibit the same functional dependence as scattering amplitudes in the Newtonian limit, which should be the weak-field limit of any quantum theory of gravity. This behavior arises independently of the presence of supersymmetry. The connection to twodimensional conformal field theory is also discussed. †[email protected] ∗Research supported by the DoE under grant DE–FG05–91ER40627.

Black Holes, Newtonian Scattering and Conformal Field Theory A
We discuss non-relativistic scattering by a Newtonian potential. We show that the gray-body factors associated with scattering by a black hole exhibit the same functional dependence as scattering amplitudes in the Newtonian limit, which should be the weak-field limit of any quantum theory of gravity. This behavior arises independently of the presence of supersymmetry. The connection to two-dime...
متن کاملGrowth of Intermediate-Mass Black Holes in Globular Clusters
We present results of numerical simulations of sequences of binary-single scattering events of black holes in dense stellar environments. The simulations cover a wide range of mass ratios from equal mass objects to 1000:10:10 M⊙ and compare purely Newtonian simulations to simulations in which Newtonian encounters are interspersed with gravitational wave emission from the binary. In both cases, ...
متن کاملThermal disc emission from a rotating black hole: X-ray polarization signatures
Thermal emission from the accretion disc around a black hole can be polarized, due to Thomson scattering in a disc atmosphere. In Newtonian space, the polarization angle must be either parallel or perpendicular to the projection of the disc axis on the sky. As first pointed out by Stark and Connors in 1977, General Relativity effects strongly modify the polarization properties of the thermal ra...
متن کاملPseudo-Newtonian Force and Potential about a Five Dimensional Rotating Black Hole
In this paper we investigate the structure of the pseudo-Newtonian force and potential about a five dimensional rotating black hole. The conditions for the force character from an attractive to repulsive are considered. It is also found that the force will reach a maximum under certain conditions.
متن کاملThe Pseudo-Newtonian Force and Potential about a Higher Dimensional Rotating Black Hole
In this paper, we study the behavior of the pseudo-Newtonian force and potential about a higher dimensional rotating black hole. We obtain conditions for the force character from an attractive to repulsive. We also find the conditions under which force attains a maximum value. The results of this paper generalizes the already found structure of force and potential about a five dimensional rotat...
