GRIJALVA CASTILLO, Sergio  and  CALCANEO-ROLDAN, Carlos. Gravitational wave enhancement as a tool to distinguish dark matter halo profiles. Rev. mex. astron. astrofis [online]. 2019, vol.55, n.2, pp.231-235.  Epub Nov 25, 2020. ISSN 0185-1101.  https://doi.org/10.22201/ia.01851101p.2019.55.02.11.

The recent success of the dark matter model has proven to be an invaluable tool for describing the formation, evolution and stability of galaxies. In this work we study the enhancement function, F, of the gravitational lensing of gravitational waves by galactic dark matter halos and show how this function may be used to distinguish between halo models. In particular we compare an isothermal sphere with an NFW type density distribution, both of which are assumed to be spherically symmetric, and find that our technique clearly distinguishes between the models.

Keywords : dark matter; gravitational lensing; gravitational waves.
