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 solution…
Observing Black Hole Phase Transitions in Extended Phase Space and Holographic Thermodynamics Approaches from Optical Features
Chatchai Promsiri, Weerawit Horinouchi, Ekapong Hirunsirisawat
The phase transitions of charged Anti-de Sitter (AdS) black holes are characterized by studying null geodesics in the vicinity of the critical curve of photon trajectories around b…
Remarks on the light ring images and the optical appearance of hairy black holes in Einstein-Maxwell-dilaton gravity
Chatchai Promsiri, Weerawit Horinouchi, Ekapong Hirunsirisawat
The behaviors of null geodesics in the spherical symmetric black holes in Einstein-Maxwell-dilaton (EMD) theory with coupling function are meticulously analyzed. We…
Scalarization of planar anti de Sitter charged black holes in Einstein-Maxwell-Scalar theory
Chatchai Promsiri, Takol Tangphati, Ekapong Hirunsirisawat +1
We construct scalarized planar charged black holes in Einstein-Maxwell-scalar (EMS) theory with the presence of a negative cosmological constant. Domains of existence of black hole…
Thermodynamics of Black Holes with Rényi Entropy from Classical Gravity
Ratchaphat Nakarachinda, Chatchai Promsiri, Lunchakorn Tannukij +1
The nonextensive nature of black holes is one of the most intriguing discoveries. In fact, the black hole entropy is a nonextensive quantity that scales by its surface area at the…
Thermodynamics and Phase Transition of Spherically Symmetric Black Hole in de Sitter Space from Rényi Statistics
Lunchakorn Tannukij, Pitayuth Wongjun, Ekapong Hirunsirisawat +2
Schwarzschild black holes in a de Sitter background were studied in terms of their thermodynamics based on the Rényi statistics. This led to thermodynamically stable black hole con…
