Generalized Polytropic Regular Black Holes in Arbitrary Dimensions
Seyed Naseh Sajadi, Supakchai Ponglertsakul, Petarpa Boonserm +2
We investigate static, spherically symmetric regular black holes with anti-de Sitter (AdS) asymptotics in arbitrary spacetime dimensions. They are solutions of Einstein gravity, so…
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…
Chiral Quartic Massive Gravity in Three Dimensions
Seyed Naseh Sajadi, Supakchai Ponglertsakul
We study New Massive Gravity (NMG) with Chern-Simons (CS), cubic, and quartic terms under the Compère-Song-Strominger (CSS) boundary conditions. By employing a semi-product of a V…
More on near-horizon charges black holes with gravitational hair in three dimensions
Seyed Naseh Sajadi, Supakchai Ponglertsakul, Julio Oliva
With the aim of continuing the exploration of near-horizon charges in higher-curvature gravity, searching for sectors leading to universal behaviors, we first provide a thorough re…
Novel exact black hole solution in Dehnen halo thermodynamics, photon circular motion and eikonal quasinormal modes
David Senjaya, Thanaporn Chuensuksan, Supakchai Ponglertsakul
Dehnen dark matter halo has been proven to be a valuable model for describing the surface brightness distributions of elliptical galaxies, yet its implications for…
Optical Signatures of q-deformed solution in Einstein-Maxwell-dilaton Gravity
Chawit Sakkawattana, Chatchai Promsiri, Supakchai Ponglertsakul
We consider null geodesics in the background of spherically symmetric object in Einstein-Maxwell-Dilaton (EMD) theory with coupling function . The spherical solut…
