A semi-analytical approach to cosmic void evolution
A. N. Baushev, A. G. Nikiforov, M. V. Barkov
We present a theoretical study of the non-linear evolution of cosmic voids -- underdense regions that occupy a large fraction of the observable Universe. We model a void as an isol…
The impact of the eccentricity on the collapse of an ellipsoid into a black hole
A. G. Nikiforov, A. N. Baushev, M. V. Barkov
We consider the gravitational collapse of a homogeneous pressureless ellipsoid. We have shown that the minimal size that the ellipsoid can reach during collapse depends on its…
How empty are the voids?
Anton N. Baushev
We find an analytical solution for the minimal matter density of a void, its central density. It turns out that the voids are not so empty: most of the voids have the central under…
The central region of a void: an analytical solution
Anton N. Baushev
We offer an exact analytical equation for the void central region. We show that the central density is solely determined by the amplitude of the initial perturbation. Our results s…
The relic neutrino composition as seen from Earth
Anton N. Baushev
Being generated, the relic neutrino background contained equal fractions of electron , muon , and taon neutrinos. We show that the gravitational field of our Galaxy…
The Hubble stream near a massive object: the exact analytical solution for the spherically-symmetric case
Anton N. Baushev
The gravitational field of a massive object (for instance, of a galaxy group or cluster) disturbs the Hubble stream, decreasing its speed. Dependence of the radial velocit…
