We explore a new technique to measure cosmic shear using Einstein rings. In Birrer et al., we showed that the detailed modeling of Einstein rings can be used to measure external shear to high precision. In this Letter, we explore how a collection of Einstein rings can be used as a statistical probe of cosmic shear. We present a forecast of the cosmic shear information available in Einstein rings for different strong lensing survey configurations. We find that, assuming that the number density…

The detection of cosmic shear on angular scales of up to half a degree is reported using 145,000 galaxies and along three separate lines of sight and it is found that the dark matter is distributed in a manner consistent with either an open universe, or a flat universe that is dominated by a cosmological constant.
