Fanaroff-Riley classification
(FR classification)
(a classification of the radio characteristics of radio sources)
The Fanaroff-Riley classification (FR classification)
is a classification of radio sources intended to distinguish
between active galactic nuclei (AGNs) versus radio galaxies:
- Class FR-I - luminosity decreases from a central point.
- Class FR-II - luminosity increases from a central point.
The first class appears to host an AGN, the second
class represents a radio galaxy with lobes (regions away
from the center emitting much of the radio electromagnetic radiation).
