Flat rotation curves in Chern-Simons modified gravity
arXiv:0807.0679 · doi:10.1103/PhysRevD.78.024037
Abstract
We investigate the spacetime of a slowly rotating black hole in the Chern-Simons modified gravity. The long range feature of frame-dragging effect under the Chern-Simon gravity well explains the flat rotation curves of galaxies which is a central evidence of dark matter. Our solution provides a different scenario of rotating space from Goedel's solution.
