Long-term variability of the composite galaxy SDSS J103911-000057: A candidate of true Type-2 AGN
XueGuang Zhang, YingFei Zhang, PeiZhen Cheng +3
In the manuscript, the composite galaxy SDSS J103911-000057 (=SDSS J1039) is reported as a better candidate of true Type-2 AGN without hidden BLRs. None broad but only narrow emiss…
