An astronomer whose joint spectrophotometry of the Twin Quasar compared the spectra along its two apparent light paths. Closely matching absorption-line properties supported <gravitational lensing>: two visible images can correspond to one distant <quasar> viewed along paths bent by intervening matter.<Spectrophotometry of the Double QSO, 0957 + 561 by Beverley J. Wills and D. Wills>[Abstract and pp. 1–3: matching absorption spectra and lens interpretation]{ref}
