WebJan 22, 2024 · The Miller-Good transformation method is employed to compute the greybody factor of bosons. To compute the Gerybody factor for fermions, we use the general method of semi-analytical bounds. We also investigate the effect of string clouds and quintessence parameters on Hawking radiation. WebHawking radiation describes hypothetical particles formed by a black hole 's boundary. This radiation implies black holes have temperatures that are inversely proportional to their … roaming giant bottomless brunch

WebJan 23, 2024 · In addition, the particles scaping from the black hole need to pass trough the potential and this change the resulting spectrum by a greybody factor ($\Gamma(\Omega)<1$). In this answer, which is very common in GR books, I utilized the Hawking radiation of Schwarzschild black hole with $\Gamma(\Omega)=1$. For more … WebSep 22, 2024 · Both the greybody factor and the power spectra of the Hawking radiation of the massless scalar are studied numerically for the full range of various parameters, including the GB coupling constant \alpha , the cosmological constant \Lambda and the coupling constant related to the scalar filed \xi . roaming globe sim card
