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…
The exponential metric represents a traversable wormhole
Petarpa Boonserm, Tritos Ngampitipan, Alex Simpson +1
For various reasons a number of authors have mooted an "exponential form" for the spacetime metric: \[ ds^2 = - e^{-2m/r} dt^2 + e^{+2m/r}\{dr^2 + r^2(dθ^2+\sin^2θ\, dϕ^2)\}. \] Wh…
