Optical Spectra of Radio-Loud and Radio-Quiet Active Galactic Nuclei [PDF]
Symposium - International Astronomical Union, 1982 Many radio galaxies have strong emission lines in their optical spectra. The fraction with such lines is much larger than in “normal” galaxies. Radio galaxies generally also have very bright nuclei; thus those with strong emission lines are similar in both respects to Seyfert galaxies.

ACTIVE GALACTIC NUCLEI IN THE ULTRAVIOLET SPECTRUM [PDF]
, 2016 Active Galactic Nucleus (AGN) produce rich, luminescent spectra across the electro- magnetic spectrum. This work focuses on topics in the ultraviolet region, where lie the broad absorption line outflows innate to Broad Absorption Line Quasi-Stellar ...

AGN outflows and the cluster cooling flow conundrum
, 2011 Temperature distributions within cores of galaxy clusters indicate gas in the core should cool down rapidly and contract. The cooling flow problem involves the hypothesis that the rapidly cooling gas should eventually condensate into unobserved molecular

The Astrophysical JournalTo facilitate new studies of galaxy-merger-driven fueling of active galactic nuclei (AGNs), we present a catalog of 387 AGNs that we have identified in the final population of over 10,000 z < 0.15 galaxies observed by the Sloan Digital Sky Survey-IV ...

The jet power, radio loudness, and black hole mass in radio-loud active galactic nuclei
, 2006 Jet formation is thought to be closely connected with the mass of the central supermassive black hole in active galactic nuclei. The radio luminosity commonly used in investigating this issue is merely an indirect measure of the energy transported ...

SMA Observations of the Archetypal Compact Steep-spectrum Radio Source 3C 303.1
The Astrophysical JournalActive galactic nucleus (AGN) feedback plays a crucial role in shaping galaxy evolution. Numerical simulations show that the kinetic energy transfer efficiency from radio jets to the interstellar medium (ISM) is relatively high, suggesting a significant ...

Physics from Time Variability of the VHE Blazar PKS 2155-304 [PDF]
, 2010 Blazars are the principal extragalactic sources of very high energy gamma-ray emission in the Universe. These objects constitute a sub-class of Active Galactic Nuclei whose emission is dominated by Doppler boosted non-thermal radiation from plasma ...

The Astrophysical JournalAbout 3%–10% of Type I active galactic nuclei (AGNs) have double-peaked broad Balmer lines in their optical spectra originating from the motion of gas in their accretion disk.
