  Various profiles of matter distribution in galactic halos (such as
Navarro-Frenk-White, Burkert, Hernquist, Moore, Taylor-Silk and others) are
considered here as the source term for the Einstein equations. We solve these
equations and find exact solutions which represent the metric of a central
black hole immersed in a galactic halo. Even though in the general case the
solution is numerical, very accurate general analytical metric, which includes
all the particular models, are found in the astrophysically relevant regime,
when the mass of the galaxy is much smaller than the characteristic scale in
the halo.
