Transverse Extragalactic Motions: a New Method for Constraining Cosmological Parameters
·

Abstract

The geometrical nature of strong lensing can provide cosmological constraints that are independent of the traditional methods. Specifically, multiple-arc systems where a single lens images multiple background objects and via a new method based on cosmological parallax from the Galaxy's motion with respect to the Cosmic Microwave Background.
