Echoes in brane worlds: ringing at a black hole--wormhole transition
Kirill A. Bronnikov, Roman A. Konoplya
Echoes are known as modifications of the usual quasinormal ringing of a black hole at late times because of the deviation of space-time from the initial black-hole geometry in a sm…
Comment on "Linear superposition of regular black hole solutions of Einstein nonlinear electrodynamics"
K. A. Bronnikov
It is argued that in the paper by A.A. Garcia-Diaz and G. Gutierrez-Cano [Phys. Rev. D 100, 064068 (2019)] on nonlinear electrodynamics coupled to general relativity, along with so…
String clouds and radiation flows as sources of gravity in static or rotating cylinders
K. A. Bronnikov
Static and stationary cylindrically symmetric space-times in general relativity are considered, supported by distributions of cosmic strings stretched in the azimuthal (), longi…
Spinor fields in spherical symmetry. Einstein-Dirac and other space-times
K. A. Bronnikov, Yu. P. Rybakov, Bijan Saha
We discuss the static spherically symmetric Einstein-spinor field system in the possible presence of various spinor field nonlinearities. We take into account that the spinor field…
Spherically symmetric black holes and wormholes in hybrid metric-Palatini gravity
K. A. Bronnikov
The so-called 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 obs…
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…
Stable exponential cosmological solutions with three different Hubble-like parameters in EGB model with a -term
K. K. Ernazarov, V. D. Ivashchuk
We consider a -dimensional Einstein-Gauss-Bonnet model with a cosmological term and two non-zero constants: and . We restrict the metrics to be diagonal ones and…
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…
Examples of stable exponential cosmological solutions with three factor spaces in EGB model with a -term
K. K. Ernazarov, V. D. Ivashchuk
We deal with Einstein-Gauss-Bonnet model in dimension with a -term. We obtain three stable cosmological solutions with exponential behavior (in time) of three scale factors…
Cylindrical Systems in General Relativity
K. Bronnikov, N. O. Santos, Anzhong Wang
With the arrival of the era of gravitational wave astronomy, the strong gravitational field regime will be explored soon in various aspects. In this article, we provide a general r…
