Matter accretion versus semiclassical bounce in Schwarzschild interior

K. A. Bronnikov, S. V. Bolokhov, M. V. Skvortsova

We discuss the properties of the previously constructed model of a Schwarzschild black hole interior where the singularity is replaced by a regular bounce, ultimately leading to a…

Hybrid metric-Palatini gravity: Regular stringlike configurations

K. A. Bronnikov, S. V. Bolokhov, M. V. Skvortsova

We discuss static, cylindrically symmetric vacuum solutions of hybrid metric-Palatini gravity (HMPG), a recently proposed theory that has been shown to successfully pass the local…

Hybrid metric-Palatini gravity: black holes, wormholes, singularities and instabilities

K. A. Bronnikov, S. V. Bolokhov, M. V. Skvortsova

The hybrid metric-Palatini theory of gravity (HMPG), proposed in 2012 by T. Harko et al., is known to successfully describe both local (solar-system) and cosmological observations.…

A possible semiclassical bounce instead of a Schwarzschild singularity

K. A. Bronnikov, S. V. Bolokhov, M. V. Skvortsova

We have previously shown that the singularity in a Schwarzschild black hole of stellar or larger mass may be avoided in a semiclassical manner by using as a source of gravity the s…

Rotating cylinders with anisotropic fluids in general relativity

S. V. Bolokhov, K. A. Bronnikov, M. V. Skvortsova

We consider anisotropic fluids with directional pressures ( is the density, const, ) as sources of gravity in stationary cylindrically symmetric…

Cylindrical wormholes: a search for viable phantom-free models in GR

K. A. Bronnikov, S. V. Bolokhov, M. V. Skvortsova

The well-known problem of wormholes in general relativity (GR) is the necessity of exotic matter, violating the Weak Energy Condition (WEC), for their support. This problem looks e…
