Query: Intermediate Mass-Ratio Inspirals with Dark Matter Minispike   The dark matter (DM) distributed around the intermediate massive black hole
(IMBH) forms an overdensity region called DM minispike. In this paper, we
consider the binary system which consists of an IMBH with DM minispike and a
small black hole. The factors which affect the evolution of the orbit include
the gravity of the system, the dynamical friction and accretion of the small
black hole caused by the DM minispike, and the radiation reaction of
gravitational waves (GWs). Using the method of osculating orbit, we find that
when the semi-latus rectum $p\ll 10^5 R_s$ ($R_s$ is the Schwarzschild radius
of the IMBH) the dominated factors are the dynamical friction and accretion
from the DM minispike, and the radiation reaction. When $p\gg 10^5 R_s$, the
gravity from the DM minispike dominates the orbital evolution. The existence of
DM minispike leads to the deviation from the Keplerian orbit, such as extra
orbital precession, henceforth extra phase shift in the GW waveform. We show
that these effects of DM minispike in GW waveforms can be detected by future
space-based GW detectors such as LISA, Taiji, and Tianqin, and the observation
of the IMBH binaries with DM minispikes may disclose the density profile of DM
minispikes.
