资源简介:

A systematic search, starting with more than 350 AGN in the XMM archive,resulted in the discovery of less than 10 candidates that could be strong FevirgulLaemitters. Combing through archives may not be the most efficient way to findsuch sources. However, all these objects exhibit a common characteristic. Theseobjects are the most extreme NLS1s with the narrowest Hb line widths and thestrongest optical FeII emission. In this proposal we target objects in the RASSsample of NLS1s that meet this criteria to determine if optical properties canbe used to identify strong Fe La emitters. This proof of concept work has thepotential to greatly increase the number of known Fe La emitters, which wouldallow us to confirm the nature of the softexcess, and identify candidates for future reverberation studies. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
