Candidate type II QSOs in SDSS III

At low redshifts, dust-obscured quasars often have strong yet narrow permitted lines in the rest-frame optical and ultraviolet, excited by the central active nucleus, earning...

在低红移环境下，被尘埃遮蔽的类星体（quasar）通常在静止系（rest frame）光学与紫外波段呈现出强而窄的容许谱线（permitted lines），这类谱线由中央活动核（central active nucleus）激发，从而……
