Radio loud and radio quiet active galactic nuclei
We have generated a sample of 409 active galactic nuclei (AGNs) for which both the radio luminosity at 5 GHz and the line luminosity in [O III] j5007 have been measured. The radio luminosity spans a range of 10 orders of magnitude, and the [O III] line luminosity spans a range of 8 orders of magnitudeÈboth considerably larger than the ranges in previous studies. We show that these two quantitie...
متن کاملLow Luminosity Radio Loud Active Galactic Nuclei
I review observational properties of low power radio loud AGN. High resolution VLBI observations allow the estimate of the jet velocity and orientation with respect to the line of sight and the determination of the Doppler factor. These data reveal rich structures, including two-sided jets and secondary components. New results on 1144+35, a giant radio source with superluminal motion are shown ...
متن کاملGamma Ray Bursts and Radio Loud Active Galactic Nuclei
We believe that the radiation we receive from Gamma-Ray Bursts (GRBs) and radio loud Active Galacti Nuclei (AGNs) originates from the transformation of bulk relativistic motion into random energy. Mechanisms to produce, collimate and accelerates the jets in these sources are uncertain, and it may be fruitful to compare the characteristics of both class of sources in search of enlightening simil...
متن کاملThe Difference between Radio-loud and Radio-quiet Active Galaxies
The recent development of unified theories of active galactic nuclei (AGN) has indicated that there are two physically distinct classes of these objects radio-loud and radio-quiet. The primary observational distinctions between the two types are: (1) The radio-loud objects produce large scale radio jets and lobes, with the kinetic power of the jets being a significant fraction of the total bolo...
متن کاملThe Jet-disk Connection: Evidence for a Reinterpretation in Radio-loud and Radio-quiet Active Galactic Nuclei
To constrain models of the jet–disc connection, we explore Eddington ratios reported in Foschini (2011) and interpret them in relation to the values in Sikora et al. across the active galactic nuclei population from radio loud quasars, their flat spectrum radio quasar subclass, the recently discovered gamma-ray loud narrow-line type 1 Seyfert galaxies, Fanaroff–Riley type I (FR I) radio galaxie...
