WebApr 6, 2024 · As the greybody factor is another no-hair quantity of black holes, this opens a new possibility that we could test general relativity by observationally searching for the Boltzmann distribution in ringdown, provided that near-extremal black holes exist in the observable region. WebJun 13, 2008 · The greybody factors we are interested in are just the transmission probabilities for wave modes propagating through this Regge–Wheeler potential. Despite comments often encountered in the literature, one can explicitly solve for r as a function of the tortoise coordinate r∗ — in terms of Lambert W functions we have r(r∗) = 2m[1 + W …

WebJan 22, 2024 · According to the results, the greybody factor is strongly influenced by the shape of the potential, which is determined by the model parameters. This is consistent with the ideas of quantum mechanics; as the potential rises, it becomes harder for the wave to penetrate.

Webthe concept of greybody factor remains obscure. Nevertheless, an attempt can be made to define the Hawking rate in the same way as asymptotically fiat space-times. Using this in [14,15], it was shown that the decay rate for scalars has the same form as the higher dimensional black holes, and can be reproduced from a conformal field theory at finite WebJun 13, 2024 · Abstract In general relativity, greybody factor is a quantity related to the quantum nature of a black hole.

"Black hole greybody factors are functions of frequency and angular momentum that characterizes the deviation of the emission-spectrum of a black hole from a pure black-body spectrum. As a result of quantum effects, an isolated black hole emits radiation that, at the black-hole horizon, matches the radiation from a perfect black body. However, this radiation is scattered by the geometry of the black hole itself. Stated more intuitively, the particles emitted by the black hole are subject to th… " - Greybody factor
