Slowly rotating Bose-Einstein Condensate confronted with the rotation curves of 12 dwarf galaxies
E. Kun, Z. Keresztes, L. Á. Gergely
We assemble a database of 12 dwarf galaxies, for which optical (R-band) and near-infrared () surface brightness density together with spectroscopic rotation curve data are a…
Spin dynamics of moving bodies in rotating black hole spacetimes
Balázs Mikóczi, Zoltán Keresztes
The dynamics of spinning test bodies, moving in rotating black hole (Kerr, Bardeen-like and Hayward-like) spacetimes, are investigated. In Kerr spacetime, all the spherical, zoom-w…
Dark Matter as a Non-Relativistic Bose-Einstein Condensate with Massive Gravitons
Emma Kun, Zoltán Keresztes, Saurya Das +1
We confront a non-relativistic Bose--Einstein Condensate (BEC) model of light bosons interacting gravitationally either through a Newtonian or a Yukawa potential with the observed…
Gravitational dynamics in a 2+1+1 decomposed spacetime along nonorthogonal double foliations: Hamiltonian evolution and gauge fixing
Cecília Gergely, Zoltán Keresztes, László Á. Gergely
Motivated by situations with temporal evolution and spatial symmetries both singled out, we develop a new 2+1+1 decomposition of spacetime, based on a nonorthogonal double foliatio…
