Bose-Einstein Condensate Dark Matter Halos confronted with galactic rotation curves
M. Dwornik, Z. Keresztes, E. Kun +1
We present a comparative confrontation of both the Bose-Einstein Condensate (BEC) and the Navarro-Frenk-White (NFW) dark halo models with galactic rotation curves. We employ 6 High…
Weak and strong field approximations and circular orbits of Kehagias-Sfetsos space-time
M. Dwornik, Zs. Horváth, L. Á. Gergely
The Kehagias-Sfetsos asymptotically flat black hole and naked singularity solutions of Hořava-Lifshitz gravity are investigated both in the weak-field and strong-field regimes. In…
Rotation curves in Bose-Einstein Condensate Dark Matter Halos
M. Dwornik, Z. Keresztes, L. Á. Gergely
The study of the rotation curves of spiral galaxies reveals a nearly constant cored density distribution of Cold Dark Matter. N-body simulations however lead to a cuspy distributio…
Bose-Einstein condensate dark matter model tested by galactic rotation curves
Marek Dwornik, Zoltán Keresztes, László Á. Gergely
Rotation curves of spiral galaxies are fundamental tools in the study of dark matter. Here we test the Bose-Einstein condensate (BEC) dark matter model against rotation curve data…
Modified gravity theories and dark matter models tested by galactic rotation curves
Marek Dwornik, Zoltán Keresztes, László Árpád Gergely
Bose-Einstein condensate dark matter model and Randall-Sundrum type 2 brane-world theory are tested with galactic rotation curves. Analytical expressions are derived for the rotati…
Galactic rotation curves in brane world models
L. Á. Gergely, T. Harko, M. Dwornik +2
In the braneworld scenario the four dimensional effective Einstein equation has extra source terms, which arise from the embedding of the 3-brane in the bulk. These non-local effec…
