WebBBC Science Focus Magazine March 2024 - Read online for free. WebThe observed dependence of AGN obscuration upon luminosity indicates a departure from the simplest unified model. The most-powerful AGNs may also be obscured by starbursts (e.g., Ballantyne 2008) or larger-scale gas clouds driven to the center of the galaxy by violent mergers or instabilities (e.g., Di Matteo et al. 2005; Hopkins et al. 2009).
WebFeb 16, 2024 · Active galactic nuclei (AGNs) are superbright regions at the centre of some galaxies – they create electromagnetic luminosity thousands of times greater that of entire galaxies from small regions no larger than the Solar System.
