From massless wormholes to massive black bounces: Shadows and multiple light rings
G. Alencar, Kirill A. Bronnikov, T. M. Crispim +2
We develop a general framework for constructing massive black bounce geometries from massless wormhole seeds by introducing a position-dependent mass function while preserving the…
Nonlinear electrodynamics and stability of spherically symmetric space-times in scalar-tensor gravity
Kirill A. Bronnikov, Rustam Ibadov, Feruza Y. Shaymanova +1
We study linear perturbations of static, spherically symmetric solutions of scalar-tensor theories (STT) of gravity from the Bergmann-Wagoner-Nordtvedt class, sourced by nonlinear…
Stability ranges of magnetic black holes and mirror (topological) stars in 5D gravity
Kirill A. Bronnikov, Sergei V. Bolokhov, Milena V. Skvortsova
We discuss static, spherically symmetric solutions to the 5D Einstein-Maxwell equations (belonging to wide classes of multidimensional solutions known at least from the 1990s) and…
Alexei Starobinsky and wormhole physics
Kirill A. Bronnikov, Milena V. Skvortsova
Alexei Starobinsky is most famous for his great contribution to cosmology, but he has considerable achievements in other branches of gravitational physics and astrophysics, such as…
Magnetic mirror stars in five dimensions
Kirill A. Bronnikov, Sergei V. Bolokhov, Milena V. Skvortsova
We discuss a class of solutions of multidimensional gravity which are formally related to black-hole solutions but can observationally look like compact stars whose surface reflect…
Overtones' outburst and Hawking evaporation of Kazakov-Solodukhin quantum corrected black hole
S. V. Bolokhov, K. A. Bronnikov, R. A. Konoplya
The Kazakov-Solodukhin black hole metric represents a spherically symmetric deformation of the Schwarzschild solution due to quantum-gravity corrections. Assuming the absence of no…
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…
On the instability of some k-essence space-times
K. A. Bronnikov, J. C. Fabris, Denis C. Rodrigues
We study the stability properties of static, spherically symmetric configurations in k-essence theories with the Lagrangians of the form , . The insta…
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…
Comment on "Construction of regular black holes in general relativity"
K. A. Bronnikov
It is claimed that the paper by Zhong-Ying Fan and Xiaobao Wang [Phys. Rev. D 94, 124027 (2016), arXiv: 1610.02636] on nonlinear electrodynamics coupled to general relativity, bein…
