SDSS Hbeta & C^IV^ reverberation mapped AGNs

It is well known that reverberation mapping of active galactic nuclei (AGNs) reveals a relationship between AGN luminosity and the size of the broad-line region, and that use of...众所周知，对活动星系核（active galactic nuclei, AGN）开展的反响映射（reverberation mapping）研究，揭示了活动星系核光度与宽线区（broad-line region）尺寸之间的关联，且相关应用于……
