Title: Detection of the lensing galaxy in PG 1115 + 080

Abstract

An image of what is believed to be the lensing galaxy of the quasar PG 1115 + 080 was obtained by using an RCA CCD at the CFHT. The photometry of the galaxy is R = 20.20 mag, V - R about 0.70 mag and (B-V) at least 0.75 mag. Comparison of the photometry to synthesized colors of redshifted galaxies suggests that the object may be a spiral with z = 0.3 to 0.45. The redshift range is also in approximate agreement with the predictions of an isothermal lens model as applied to PG 1115 + 080. Photometry of the individual QSO components suggests that all components have the same colors. The flux ratio of component A1 to A2 was about 1.27 on Feb. 19, 1986. 20 references.
