On the Black Hole Mass---X-ray Excess Variance Scaling Relation for Active Galactic Nuclei in the Low-mass Regime

Hai-Wu Pan, Weimin Yuan, Xin-Lin Zhou +2

Recent studies of active galactic nuclei (AGN) found a statistical inverse linear scaling between the X-ray normalized excess variance ${\sigma }_{\mathrm{rms}}^2$ (variability amplitude) and t…
