Description

Aspects related to black holes surrounded by the astrophysical environment are underappreciated and require profound attention and effort. From an astrophysical viewpoint, we know that dark matter is asserted to be an undetected form of an elementary particle that is not visible, does not interact and contributes almost 27% to the matter-energy of the universe. The development of gravitational wave astronomy may fundamentally provide an understanding of the universe with such an invisible entity. Here, I would discuss the detection prospects of dark matter existence with an extreme mass ratio inspiral system where a stellar-mass object inspirals a supermassive black hole in the presence of an astrophysical environment. We estimate the gravitational wave fluxes, orbital evolution and gravitational wave dephasing that exceptionally highlight the detection prospects of such an environment in gravitational wave observations with low-frequency detectors.
