Query: Implications of Intermediate Mass Black Hole in globular cluster G1 on
  Dark Matter detection   Recently there has been a growing evidence in favor of the presence of an
Intermediate Mass Black Hole in the globular cluster G1, in Andromeda Galaxy.
In this paper, we explore whether the adiabatic growth in the dark matter
density due to the presence of a black hole could result in an observable gamma
ray signal due to dark matter annihilation in this globular cluster. Starting
from an initial NFW matter profile, with density parameters consistent with G1
observations, we find that indeed, if the spike in the density has been formed
and has survived till present, the signal could be observed by GLAST and
current ACT detectors.
