Mutual influence of photon sphere and non-commutative parameter in various non-commutative black holes: Towards evidence for WGC
Non-commutative black holes (NCBH), due to the non-commutativity of spacetime
coordinates, lead to a modification of the spacetime metric. By replacing the Dirac delta …

Large and ultracompact Gauss-Bonnet black holes with a self-interacting scalar field
We consider the Einstein-scalar-Gauss-Bonnet theory, and study the case where a negative
cosmological constant is replaced by a more realistic, negative scalar-field potential. We …

Nutty Kaluza-Klein dyons revisited
I Bogush, G Clément, D Gal'tsov, D Torbunov - Physical Review D, 2021 - APS
We extend the previous analysis of (locally) asymptotically flat solutions of Kaluza-Klein (KK)
theory by assuming that the dilaton charge is an independent parameter. This corresponds …

Hyperelliptic functions and motion in general relativity
Analysis of black hole spacetimes requires study of the motion of particles and light in these
spacetimes. Here exact solutions of the geodesic equations are the means of choice …
