Vortex State of Ultralight Dark Matter and the Fornax Timing Problem
V. Gorkavenko, O. Barabash, T. Gorkavenko +4
We investigate the impact of the vortex state of the ultralight dark matter (ULDM) on the dynamical friction acting on moving globular clusters. Comparing this force with that for…
Effects of Curvature-Scalar Coupling on Vacuum Energy in Flat (3+1)-Dimensional Space-Time
Volodymyr Gorkavenko, Oleh Barabash, Pavlo Nakaznyi +3
We investigated how a magnetic topological defect affects the vacuum polarization of a charged massive scalar field in a flat -dimensional space-time. The defect was modeled…
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…
