Anisotropic X-ray emission in active galactic nucleus accretion discs
Straightforward models of X-ray reflection in the inner region of accretion discs predict that the primary X-ray flux and the flux reflected off the surface of the disc should vary together, albeit with a short light traveltime delay. Most of the observations, however, show that the X-ray flux can vary while the reflected features remain constant. Here we propose a simple explanation for this. ...
متن کاملFactors 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...
متن کاملActive Galactic Nuclei and the Cosmic X-Ray Background
Active Galactic Nuclei (AGNs) are the most luminous objects in the Universe (besides Gamma-Ray Bursts). Typical spatial scales for these objects are estimated from time variability, giving sizes of around one parsec (Clavel al. 1991, Peterson et al. 1992), similar to our solar system, but with typical luminosities 1011 larger than the Sun. It is believed that their energy comes from the inflow ...
متن کاملGalactic X-ray binary jets
With their relatively fast variability time-scales, Galactic X-ray binaries provide an excellent laboratory to explore the physics of accretion and related phenomena, most notably outflows, over different regimes. After comparing the phenomenology of jets in black hole systems to that of neutron stars, here I discuss the role of the jet at very low Eddington ratios, and present preliminary resu...
متن کاملJets 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 ...
