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…
Velocity dispersion profiles of dwarf spheroidal galaxies with self-interacting ultralight dark matter
K. Korshynska, E. V. Gorbar, Y. M. Bidasyuk +2
Dark-matter-dominated dwarf galaxies provide an excellent laboratory for testing dark matter models at small scale and, in particular, the ultralight dark matter (ULDM) class of mo…
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…
Vortex Lines in Ultralight Bosonic Dark Matter around Rotating Supermassive Black Holes
K. Korshynska, O. O. Prykhodko, E. V. Gorbar +2
Theoretical analysis of the interaction between superfluid dark matter and rotating supermassive black holes offers a promising framework for probing quantum effects in ultralight…
