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…
