WebAug 23, 2014 · Presentation Transcript. AGN Jason Jeong. Intro: AGN AGN stands for active galactic nuclei. It is the core of the galaxy that produces more radiation than the rest of the galaxy. Intro: AGN It is an active galaxy because of one of the following: • Nuclear optical continuum emissionNuclear infra-red emissionBroad optical emission linesNarrow ... WebMar 7, 2011 · The Unified Model of AGN. In the unified model, two main types of AGN, broad-line (or type I) and narrow-line (type II) are postulated to be the same sort of object, whose appearance depends on the viewer’s line of sight. The two types are so-named because of the characteristic emission lines in their spectra – type I AGN have very …

WebNowadays a standard theoretical model is generally accepted to explain the existence of the whole AGN family. It is simply called the Unified Model (see Fig. 3.5). The basic principle is the following: every type of AGN is the same phenomenon, at various luminosities, observed with different viewing angles, which, combined with the anisotropy ... Weba moderate CF model with a cold feedback mechanism and AGN feedback. Heat conduction does not really help. 2.3. Adding turbulence: back to a moderate CF model Let me take a recent example, and critically review the results of Parrish et al. (2010). Parrish et al. (2010) consider heat conduction as the heating source. They add to their simulations a alcotan biv
