Damping of dynamical friction force in self-interacting ultralight dark matter and Fornax timing problem
E. V. Gorbar, O. V. Barabash, V. M. Gorkavenko +3
The dynamics of globular clusters in the Fornax dwarf galaxy pose a challenge for the standard cold dark matter and can be used to test other models of dark matter. We study this d…
Magnetic field in vacuum of quantum spinor matter induced by a cosmic string in three-dimensional space
Yu. I. Pylypchuk, P. O. Nakaznyi, O. V. Barabash +2
A linear magnetic topological defect (cosmic string) is modeled as a magnetic flux-carrying tube that is impenetrable to external spinor matter. The matter field is quantized in th…
Impact of space-time curvature coupling on the vacuum energy induced by a magnetic topological defect in flat space-time of arbitrary dimension
V. M. Gorkavenko, O. V. Barabash, I. V. Ivanchenko +4
We have investigated vacuum polarization of a quantized charged massive scalar field in the presence of a magnetic topological defect, modeled as an impenetrable tube of finite thi…
Analytic calculation of dynamical friction for Plummer sphere in ultralight dark matter
O. V. Barabash, T. V. Gorkavenko, V. M. Gorkavenko +4
The dynamical friction force acting on a spatially extended probe (globular clusters and dwarf galaxies) moving in the environment of ultralight bosonic dark matter in the state of…
