IUE Spectra of Seyvert 1 Galaxy NGC 7469- BLR Characteristics of NGC 7469

Hyung, Siek; Son, Dong-Hoon

From the line ratios of Si III] 1892 to C III] 1909 (Feibelman & Aller 1987), we estimated the BLR electron densities and their changes of Seyfert 1 galaxy NGC 7469 using IUE spectra observed from June 11 to July 29, 1996 (Wanders et al. 1997). We separated blended Si III] and C III] lines using the STARLINK/DIPSO and measured their fluxes wit…
