A Novel Kerr-like Black Hole in a General Double Power Law Dark Matter Environment: Geometry, Spectroscopy, and Energy Extraction
Supakchai Ponglertsakul, David Senjaya
We construct a novel Kerr-like black hole solution embedded in a general double power law dark matter environment by applying the Newman--Janis algorithm to a Schwarzschild-like se…
Novel Kerr-Hernquist Black Hole: Quasibound State, Scalar Cloud, Bomb, Superradiant Scattering
David Senjaya
We present a novel rotating black hole solution surrounded by a Hernquist dark matter halo, obtained by applying the Newman--Janis algorithm to the exact Schwarzschild--Hernquist s…
Exact Einsteinian Black Hole Solution in Dark Matter Environment
David Senjaya
Motivated by the growing recent interest in black hole solutions immersed in astrophysical dark matter environments, we construct an exact static, spherically symmetric black hole…
Tuning A Rotating Black Hole Spectrum with Dark Matter Halo: Quasibound States, Scalar Cloud, Black Hole Bomb and Superradiant Scattering
David Senjaya
We investigate the spectral dynamics of a rotating black hole embedded in a Dehnen dark matter halo, where quasibound states and superradiant scattering jointly characte…
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…
