Gravitational radiation and dynamical degrees of freedom in DGP gravity
M. Khlopunov, D. V. Gal'tsov
The paper is devoted to the study of gravitational radiation in the DGP model of gravity. It includes a detailed analysis of dynamical degrees of freedom of tensionless DGP and the…
Glued massive particles surfaces
Igor Bogush, Kirill Kobialko, Dmitri Gal'tsov
A novel generalization of photon surfaces to the case of massive charged particles is given for spacetimes with at least one isometry, including stationary ones. A related notion o…
Rotating traversable wormholes in Einstein-Maxwell theory
Gérard Clément, Dmitri Gal'tsov
It is well-known that traversable wormhole solutions to the Einstein equations require the existence of an exotic matter source violating the null energy condition. An apparent exc…
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…
