摘要：

We present polarimetric evidence that the extraordinarily luminous galaxy FSC 10214+4724 harbors a hidden QSO. In polarized flux we see broad emission lines of C III] lambda 1909, C IV lambda 1550, and Ly alpha/N v lambda 1240. The narrow emission lines that dominate the total flux spectrum are unpolarized. Recent images have indicated that FSC 10214+4724 is actually gravitationally lensed, and we find strong evidence for Mg II lambda 2800 absorption at z = 1.316 in the spectrum of the QSO and weaker evidence for a possible continuum and absorption system at z = 0.893. Both of these systems could represent galaxies that contribute to the lensing.
