Gravitational radiation reaction around a static black hole surrounded by a Dehnen type dark matter halo
Amjad Ashoorioon, Roberto Casadio, Khadije Jafarzade +2
We consider the motion of a particle in the geometry of a Schwarzschild-like black hole embedded in a dark matter (DM) halo with Dehnen type density profile and calculate the orbit…

Extended Effective Field Theory of Dark Energy: Ghost Condensate Dark Energy with Sextic Dispersion Relation in de Sitter Spacetime
A. Ashoorioon, M. B. Jahani Poshteh, A. Yousefi-Sostani
We continue our studies of the ghost condensate (GC) with sixth-order dispersion relation. Contrary to the GC with quartic dispersion relation, we find that the correction to the N…
