Phys. Rev. D 78, 024037 (2008) [5 pages]Flat rotation curves in Chern-Simons modified gravityReceived 5 October 2007; published 23 July 2008 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 Gödel’s solution. © 2008 The American Physical Society URL:
