Quasar composite made from bright QSOs

Quasi-stellar object (QSO) spectral templates are important both to QSO physics and for investigations that use QSOs as probes of intervening gas and dust. However, combinations...类星体（Quasi-stellar object, QSO）的光谱模板（spectral templates）不仅对类星体物理学研究至关重要，同时也可为那些以类星体作为居间气体与尘埃探测探针的相关研究提供关键支撑。然而，组合……
