Quasi-bound States of Scalar field inside the Dyonic Kerr-Sen Black Hole
David Senjaya, Tinnagrit Songkeaw, Piyabut Burikham
We found sets of exact analytic quasi-stationary states of a massive scalar field in a dyonic Kerr-Sen black hole~(DKSBH) background in the maximally extended spacetime region. A c…

Thermodynamics and Geometrical Optics of Reissner Nordstrom de Sitter Black Holes in Noncommutative Geometry
Phongsakorn Sereewat, David Senjaya, Piyabut Burikham
We investigate the thermodynamic, optical, and dynamical properties of Reissner-Nordstrom-de Sitter black holes in a noncommutative spacetime with a minimal length scale Theta. Wit…
