[PDF] Top 20 The Sloan Digital Sky Survey Reverberation Mapping project: : no evidence for evolution in the M• σ* Relation to z~1

... Therefore, the uncertainty of the virial masses is σ vir = (0.5 σ L ) 2 + (2 σ FWHM ) 2 = 0.39 dex, roughly consistent with expectation ( e.g., Shen 2013 ) . In addition, this approach yields a ... See full document
