Harnessing stellar kinematics to constrain dark energy with the double-source-plane gravitational lens SDSS J0946+1006
SDSS J0946+1006 is an attractive target for measuring cosmological parameters through lens modelling. It is the best-studied galaxy-scale strong gravitational lens with multiple sources whose redshift separations are well-suited to constraining the dark energy equation of state. However, multi-plane lens models with fr...
