- SDSS J2222+2745 (z = 0.489)
- Redshift
- 2.805
Quasar at z = 2.8 lensed into six images up to 15.1 arcsec apart, found in the Sloan Giant Arcs Survey (Dahle et al. 2013). Time delays: Dahle et al. (2015); lens model and delay predictions: Sharon et al. (2017). The multiple images were also used to measure the quasar's black-hole mass by reverberation mapping.
