B-Inflation
Alexey Anisimov, Eugeny Babichev, Alexander Vikman
We propose a novel model of inflation based on a large class of covariant effective actions containing only the second derivatives of a scalar field. The initial conditions leading…
The Accretion of Dark Energy onto a Black Hole
E. Babichev, V. Dokuchaev, Yu. Eroshenko
The stationary, spherically symmetric accretion of dark energy onto a Schwarzschild black hole is considered in terms of relativistic hydrodynamics. The approximation of an ideal f…
Gravitational radiation from rotating monopole-string systems
E. Babichev, V. Dokuchaev, M. Kachelriess
We study the gravitational radiation from a rotating monopole-antimonopole pair connected by a string. While at not too high frequencies the emitted gravitational spectrum is descr…
Dark energy cosmology with generalized linear equation of state
E. Babichev, V. Dokuchaev, Yu. Eroshenko
Dark energy with the usually used equation of state , where is hydrodynamically unstable. To overcome this drawback we consider the cosmology of a perfect fluid w…
Gravitational radiation from chiral string cusps
Eugeny Babichev, Vyacheslav Dokuchaev
We calculate the gravitational radiation from a cusp of the chiral cosmic strings as a function of the current on the string in the limit of small values of the current. The smooth…
Energy, momentum and angular momentum radiation from chiral cosmic string loops
E. Babichev, V. Dokuchaev
We derived expressions for energy, momentum and angular momentum losses due to gravitational and electromagnetic radiation from the closed superconducting chiral cosmic strings of…
