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…
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…
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…
Dynamical friction in rotating ultralight dark matter galactic cores
V. M. Gorkavenko, O. V. Barabash, T. V. Gorkavenko +5
Dynamical friction and stellar orbital motion in spiral galaxies with dark matter composed of ultralight bosons in the state of rotating Bose-Einstein condensate (BEC) are studied.…
