Supergravity -branes with scalar charge
Igor Bogush, Dmitri Gal'tsov
Standard dilatonic supergravity -branes have scalar charges that are not independent parameters, but are determined by the brane tension and Page charges. This feature can be tr…
The geometry of massive particle surfaces
Kirill Kobialko, Igor Bogush, Dmitri Gal'tsov
We propose a generalization of Claudel, Virbhadra, and Ellis photon surfaces to the case of massive charged particles, considering a timelike hypersurface such that any worldline o…
Photon surfaces, shadows and accretion disks in gravity with minimally coupled scalar field
Igor Bogush, Dmitri Gal'tsov, Galin Gyulchev +3
In this article, we conduct a sequential study of possible observable images of black hole simulators described by two recently obtained rotating geometries in Einstein gravity, mi…
Slice-reducible conformal Killing tensors, photon surfaces and shadows
Kirill Kobialko, Igor Bogush, Dmitri Gal'tsov
We generalize our recent method for constructing Killing tensors of the second rank to conformal Killing tensors. The method is intended for foliated spacetimes of arbitrary dimens…
