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…
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…
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…
Dynamical galactic effects induced by stable vortex structure in bosonic dark matter
K. Korshynska, Y. M. Bidasyuk, E. V. Gorbar +2
The nature of dark matter (DM) remains one of the unsolved mysteries of modern physics. An intriguing possibility is to assume that DM consists of ultralight bosonic particles in t…
Stable vortex structures in colliding self-gravitating Bose-Einstein condensates
Y. O. Nikolaieva, Y. M. Bidasyuk, K. Korshynska +3
A key feature of ultra-light dark matter composed by bosons is the formation of superfluid Bose-Einstein condensate (BEC) structures on galactic scales. We study collisions of BEC…
