Shadows and Polarimetric Signatures of Rotating Simpson-Visser Black Holes with Thick Disk Illumination

In this manuscript, we investigate the shadow and polarization images of a Simpson-Visser rotating black hole surrounded by a ballistic approximation accretion flow model. Solving the numerically geodesic and radiative transfer equations, we discuss the influence of the regularization parameter $g$, spin parameter $a$,...

Schottky Anomaly and Microstructure of de Sitter Black Holes in Conformal Killing Gravity

We investigate the thermodynamic properties of charged de Sitter (dS) black holes in Conformal Killing Gravity (CKG), whose static spherically symmetric metric contains the quartic term [Formula: see text]. By treating the spacetime region between the event and cosmological horizons as a single effective thermodynamic...
