Mergers as a probe of particle dark matter

Black holes below Chandrasekhar mass limit (1.4 $M_{\odot}$) can not be produced via any standard stellar evolution. Recently, gravitational wave experiments have also discovered unusually low black whose origin is yet to known. We propose a simple novel formation mechanism of such holes. Non-annihilating particle dark matter, owing their interaction with nuclei, gradually accumulate inside compact stars, and eventually swallows them holes, ordinarily impermissible by the limit. point out several avenues test this proposal, concentrating on cosmic evolution binary merger rates.
