Kerr-referenced analytical parametrization of rotating black holes in dynamical Chern-Simons gravity
Sardor Murodov, Bahodir Ahmedov, Bekzod Rahmatov +2
Rotating black holes in dynamical Chern-Simons gravity are known nonperturbatively mainly through numerical solutions, which limits their direct use in strong-field applications. W…
Slow rotation of a localized Kalb-Ramond wormhole: Wald charges and fractional quadrupolar hair
Sardor Murodov
We construct an action-consistent slow-rotation branch, through second order, for a traversable wormhole supported by a phantom scalar, a scalar-localized radial string sector, and…

Sardor Murodov, Bekzod Rahmatov, Islom Egamberdiev +3
We study the static, spherically symmetric electric branch of spontaneously vectorized Einstein-vector-Gauss-Bonnet black holes close to its Schwarzschild bifurcation. A weakly non…
Blandford-Znajek Scaling in a Power-Law Rotating Kalb-Ramond Geometry: Magnetic-Flux Systematics and Bayesian Identifiability
Sardor Murodov, Olimjon Kholturayev, Bekzod Rahmatov +3
Relativistic jets from spinning black holes offer a possible strong-field probe of gravity through the Blandford-Znajek mechanism. We study the leading jet-power scaling in the fou…

Einstein--scalar--Gauss--Bonnet (EsGB) gravity provides a physically motivated framework for testing strong-field deviations from the Schwarzschild geometry through scalar hair. We…

Generalized Proca theory supplements gravity with a massive vector field whose derivative self-interactions can support black holes carrying primary vector hair. In the asymptotica…
