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.…
Weak-field limit of conformal Weyl gravity
O. V. Barabash, H. P. Pyatkovska
We study the weak-field limit of the conformal Weyl gravity suggested by Mannheim as an alternative to Einstein's General Relativity modeling both dark matter and dark energy. We s…
Newtonian Limit of Conformal Gravity
O. Barabash, Yu. Shtanov
We study the weak-field limit of the static spherically symmetric solution of the locally conformally invariant theory advocated in the recent past by Mannheim and Kazanas as an al…
Collapse of topological texture
O. V. Barabash, Yu. V. Shtanov
We study analytically the process of a topological texture collapse in the approximation of a scaling ansatz in the nonlinear sigma-model. In this approximation we show that in fla…
