The LAMOST QSO Catalog DR1-5
We identified about 42,500 quasars with the spectra from LAMOST five-year regular survey (Ai et al. 2016; Dong et al. 2018; Yao et al. 2019). Among all LAMOST quasars, ∼24,000 quasars are discovered by LAMOST idenpendently, which is 56% of the whole sample. Included in the catalog are celestial positions, measurements of the broad emission lines, and the estimations of black hole masses. LAMOST quasar catalog provides not only a great supplment to the new quasar discoveries, but also a large database for investigating quasar spectral variability and discovering unusual AGNs, including changing-look quasars (Yang et al. 2018).
