  • noun Plural form of AGN.


Sorry, no etymologies found.


  • Supermassive black holes, accretion disks, AGNs/quasars, the associated jets/blazars, etc are among the most active areas of research in astrophysics today.

  • Ideas stand or fall on the scientific merits, and the material you posted has nothing to do with DRAGNs, or even AGNs; Peratt's stuff, for example, is about the formation and evolution of galaxies and, while certainly creative, clearly fails.

    Supermassive Black Holes Spinning Backwards Create Death Ray Jets? | Universe Today

  • A leading theory of ordinary AGNs is that galaxy mergers trigger accretion, creating quasars in both galaxies AGNs in the hearts of the giant elliptical galaxies in rich clusters are thought to be fueled by a different mechanism, cooling flow.

  • To understand the mechanisms of particle acceleration in active galactic nuclei (AGNs), neutron stars, and supernova remnants (SNRs).

  • To properly determine the luminosities of these 12 AGNs, we must correct them for their host-galaxy starlight contributions using high-resolution images.

  • AGNs in our ground-based monitoring sample, as well as one white dwarf which will be used as a PSF model.

  • High-resolution ACS images of the host galaxies of more luminous AGNs reveal that the black hole mass-bulge luminosity and black hole mass-bulge mass relationships for AGNs are not well constrained and arise from what appear to be fundamentally flawed data sets.

  • The correction will be substantial for each of the 12 sources we will monitor, as the AGNs are relatively faint and embedded in nearby, bright galaxies.

  • The radius-luminosity (R-L) relationship is currently the fundamental basis for all techniques used to estimate black hole masses in AGNs, in both the nearby and distant universe.
