Radio Galaxy

(RG)
(a galaxy emitting a lot of radio)

A Radio Galaxy (RG) is a Galaxy emitting a lot of Radio Electromagnetic Radiation (EMR) (Radio-Loud). They have been found with as much as 1039 watts of power in the radio spectrum. Distant radio galaxies are useful as they are relatively easily observed.

An SFRG (Star Forming Radio Galaxy) has rest-frame Ultraviolet (UV) spectral features consistent with a Starburst Galaxy.

A Radio Galaxy is generally an Active Galaxy. Quasars (QSO) and Blazars with a similar radio spectrum are called Radio-Loud Quasars and Radio-Loud Blazars and are assumed to be more distant radio-loud Radio Galaxies.
