Greybody factors for massive scalar field emitted from black holes in dRGT massive gravity
Petarpa Boonserm, Sattha Phalungsongsathit, Kunlapat Sansuk +1
Greybody factors are transmission probabilities of the Hawking radiation, which are emitted from black holes and can be obtained from the gravitational potential of black holes. Th…
Greybody factor for massive fermion emitted by a black hole in dRGT massive gravity theory
P. Boonserm, C. H. Chen, T. Ngampitipan +1
The greybody factor of the massive Dirac field around the black hole in the dRGT massive gravity theory is investigated using the rigorous bound and the WKB approximation methods.…
Decomposition of total stress-energy for the generalised Kiselev black hole
Petarpa Boonserm, Tritos Ngampitipan, Alex Simpson +1
We demonstrate that the anisotropic stress-energy supporting the Kiselev black hole can be mimicked by being split into a perfect fluid component plus either an electromagnetic com…
ISCOs and OSCOs in the presence of positive cosmological constant
Petarpa Boonserm, Tritos Ngampitipan, Alex Simpson +1
Normally one thinks of the observed cosmological constant as being so small that it can be utterly neglected on typical astrophysical scales, only affecting extremely large-scale c…
Greybody factor for black string in dRGT massive gravity
P. Boonserm, T. Ngampitipan, P. Wongjun
The greybody factor from the black string in the de Rham-Gabadadze-Tolley (dRGT) massive gravity theory is investigated in this study. The dRGT massive gravity theory is one of the…
Near-horizon geodesics for astrophysical and idealised black holes: Coordinate velocity and coordinate acceleration
Petarpa Boonserm, Tritos Ngampitipan, Matt Visser
Geodesics (by definition) have an intrinsic 4-acceleration zero. However, when expressed in terms of coordinates, the coordinate acceleration can very easily be non…
Greybody factor for black holes in dRGT massive gravity
Petarpa Boonserm, Tritos Ngampitipan, Pitayuth Wongjun
In general relativity, greybody factor is a quantity related to the quantum nature of a black hole. A high value of greybody factor indicates a high probability that Hawking radiat…
