On rates of supernovae strongly lensed by galactic haloes in Millennium
  Simulation
  We make use of publicly available results from N-body Millennium Simulation
to create mock samples of lensed supernovae type Ia and core-collapse.
Simulating galaxy-galaxy lensing we derive the rates of lensed supernovae and
find than at redshifts higher that 0.5 about 0.06 per cent of supernovae will
be lensed by a factor two or more. Future wide field surveys like Gaia or LSST
should be able to detect lensed supernovae in their unbiased sky monitoring.
Gaia (from 2013) will detect at least 2 cases whereas LSST (from 2018) will see
more than 500 a year. Large number of future lensed supernovae will allow to
verify results of cosmological simulations. The strong galaxy- galaxy lensing
gives an opportunity to reach high-redshift supernovae type Ia and extend the
Hubble diagram sample.
