Plasma effects on gravitational lensing and shadow observables of a Kerr-like black hole in a dark matter halo
Connor McMillin, Zhichen Guan, Owen Gartlan +3
Plasma surrounding a black hole modifies light propagation and can alter the observed shadow, potentially affecting the interpretation of Event Horizon Telescope data. We study the…

Superradiant Suppression of Non-minimally Coupled Scalar fields for a Rotating Charged dS Black Hole in Conformal Weyl Gravity
Owen Gartlan, Jacob March, Leo Rodriguez +2
In this study, we present an analytical investigation of the superradiant scattering of a massive charged conformally coupled scalar field in rotating charged black hol…
