Probing Dark Matter Substructure in Lens Galaxies

  title={Probing Dark Matter Substructure in Lens Galaxies},
  author={Masashi Chiba},
We investigate the effects of numerous dark matter subhalos in a galaxy-sized halo on the events of strong lensing, to assess their presence as expected from the cold dark matter scenario. Lens galaxies are represented by a smooth ellipsoid in an external shear field and additional cold dark matter subhalos taken from Monte Carlo realizations which accord… CONTINUE READING
