Regge-Wheeler equation, linear stability, and greybody factors for dirty black holes
Petarpa Boonserm, Tritos Ngampitipan, Matt Visser
So-called "dirty" black holes are those surrounded by non-zero stress-energy, rather than vacuum. The presence of the non-zero stress-energy modifies key features of the black hole…
Reflection and transmission resonances and accuracy of the wkb method
Tritos Ngampitipan, Petarpa Boonserm
In this paper, we calculate the transmission and reflection amplitudes of wave functions for different potentials such as the delta function, the rectangular barrier, the Eckart po…
Bounding the greybody factors for the Reissner-Nordström black holes
Tritos Ngampitipan, Petarpa Boonserm
A black hole can emit radiation called Hawking radiation. Such radiation seen by an observer outside the black hole differs from the original radiation near the horizon of the blac…
