We present new observations of two z = 0.12 strong-lensing elliptical galaxies , originally discovered from the SDSS-IV MaNGA survey , using the new FOCAS IFU spectrograph on the Subaru Telescope . For J1436+4943 , our observations confirm the identification of this system as a multiple-image lens , in a cusp configuration , with Einstein radius \theta _ { Ein } = 2.0 arcsec . For J1701+3722 , the improved data confirm earlier hints of a complex source plane , with different configurations evident in different emission lines . The new observations reveal a previously unseen inner counter-image to the [ O iii ] arc found from MaNGA , leading to a smaller revised Einstein radius of \theta _ { Ein } = 1.6 arcsec . The inferred projected masses within the Einstein apertures ( 3.7–4.7 kpc ) are consistent with being dominated by stars with an initial mass function ( IMF ) similar to that of the Milky Way , and a dark matter contribution of \sim 35 per cent as supported from cosmological simulations . These results are consistent with ‘ pure lensing ’ analyses of lower-redshift lenses , but contrast with claims for heavier IMFs from combined lensing-and-dynamical studies of more distant early-type galaxies .
