我们目前的偏振证据表明，非常明亮的星系FSC 10214+4724窝藏一个隐藏的类星体。在偏振通量中，我们看到C III] λ1909、C IV λ1550和Lyα/NV λ1240的宽发射线。占总通量谱主导地位的窄发射线是非偏振的。最近的图像显示FSC 10214+4724实际上是引力透镜，我们在类星体的光谱中发现了Mg II λ2800在z = 1.316处吸收的强有力证据，以及在z = 0.893处可能存在连续谱和吸收系统的弱证据。这两个系统都可以代表有助于透镜效应的星系。
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] λ1909, C IV λ1550, and Lyα/N V λ1240. 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 λ2800 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.
