In this presentation, I will discuss the possible consequences of the Sommerfeld enhancement of dark matter annihilation in galaxies. I will show that the Sommerfeld enhancement of the dark matter annihilation cross section via invisible sterile neutrino channel can give a sufficiently large annihilation rate to solve the core-cusp problem in astrophysics. We will also discuss if there is any possible signal of the Sommerfeld enhancement of dark matter annihilation based on the recent FermiLAT data.
