J/PASJ/55/947  Blazars and Seyfert galaxies accretion rates (Liang+, 2003)

A possible signature of connection between blazars and Seyfert galaxies. Liang E.-W. <Publ. Astron. Soc. Jap., 55, 947-951 (2003)> =2003PASJ...55..947L
ADC_Keywords: QSOs ; Galaxies, Seyfert ; Mass loss ; Redshifts Keywords: galaxies: active - galaxies: BL Lacs - galaxies: evolution - galaxies: nuclei - galaxies: Seyfert Abstract: Accretion rates and their correlation with cosmological redshifts for a sample of blazars and Seyfert galaxies are presented. The sample includes 77 blazars (28 FSRQs, 26 LBLs, and 23 HBLs) and 60 Seyfert galaxies, of which the extended spectral energy distribution information and redshifts are available. Within the framework of accreting black holes, the accretion rates for these sources were estimated based on their bolometric luminosities. File Summary:
