Gravitational nanolensing from subsolar mass dark matter halos.

CHEN J. and KOUSHIAPPAS S.M.

Abstract (from CDS):

We investigate the feasibility of extracting the gravitational nanolensing signal due to the presence of subsolar mass halos within galaxy-sized dark matter halos. We show that subsolar mass halos in a lensing galaxy can cause strong nanolensing events with shorter durations and smaller amplitudes than microlensing events caused by stars. We develop techniques that can be used in future surveys such as Pan-STARRS, LSST, and OMEGA to search for the nanolensing signal from subsolar mass halos.
