Factors Determining Variability Time in Active Galactic Nucleus Jets

The relationship between observed variability time and emission region geometry is explored for the case of emission by relativistic jets. The approximate formula for the jet-frame size of the emission region, R = Dc∆tobs is shown to lead to large systematic errors when used together with observed luminosity and assumed or estimated Doppler factor D to estimate the jet-frame photon energy densi...

Jets in Active Galactic Nuclei

The jets of active galactic nuclei can carry a large fraction of the accreted power of the black-hole system into interstellar and even extragalactic space. They radiate profusely from radio to X-ray and γ-ray frequencies. In the most extreme cases, the outward flow speeds correspond to high Lorentz factors that can reach 40 or more. This chapter displays images at various wavebands as well as ...

Ultracompact jets in active galactic nuclei

We study the properties of ultracompact jets in several prominent radio sources (Cygnus A, 3C 309.1, 3C 345, 3C 395, 4C 39.25, and 1038+528A), using the frequency dependence of observed position of the optically thick jet core. Frequency dependent offsets of the core positions are used for calculating the luminosities, magnetic fields, and geometrical properties of the jets. Opacity effects are...

Relativistic Jets in Active Galactic Nuclei

This review discusses the basic characteristics of the jets in active galactic nuclei (AGN). It concentrates on the highly relativistic variety found in blazars, since these are the closest cousins to the jets seen in some X-ray binaries (microquasars) and the collimated, ultra-fast flows inferred to exist in gamma ray bursts. The fastest AGN jets are gamma-ray bright, with flow Lorentz factors...

X-ray variability time scales in Active Galactic Nuclei

X-ray variability in Active Galactic Nuclei (AGN) is commonly analysed in terms of the Power Spectral Density (PSD). The break observed in the power spectrum can be interpreted as a characteristic X-ray variability time scale. Here we study variability properties within the framework of clumpy accretion flows, in which shocks between accreting elements account for the UV and X-ray emissions. We...
