Radio galaxy
Radio galaxies and their relatives, radio-loud quasars and blazars, are types of active galaxy that are very luminous at radio wavelengths (up to 1038 W between 10 MHz and 100 GHz).
Radio Galaxy :
Extragalactic radio sources are objects that emit a continuum of radio wavelengths and that lie beyond the confines of the Galaxy were divided in the 1950s into two classes depending on whether they present spatially extended or ...

radio galaxy - (n.)
Any of a class of galaxies whose luminosity is greatest in radio wavelengths.
Radio Galaxy: A galaxy that is emitting most of its energy in the form of radio waves rather than light in or near the visible bands where stars emit most of their radiation. This means that radio galaxies are dominated by some non-stellar process.

A radio galaxy, the bulk of whose radio emission comes from two sources on opposite sides of the visual galaxy.
The radio galaxy MRC 1138-262, also called the "Spiderweb Galaxy" is a large galaxy in the making. At 10.6 billion light years away, we see it in the process of forming only 3 billion years after the Big Bang.
This radio galaxy Centaurus A (NGC 5128) provides an example of how dust can affect our view of a galaxy, and how going to redder wavelengths helps penetrate interstellar dust.

One common type of radio galaxy is often called a core"halo radio galaxy. As illustrated in Figure 25.
A radio galaxy such as M87 could be found anywhere within z=10 by current techniques. These wavelengths are domanated by nonthermal processes such as synchrotron radiation.

If the line of sight is through the dust ring, the central source is obscured and the AGN would be seen as a radio galaxy. If the dust ring is tilted to our line of sight, the central source would be visible, corresponding to
a quasar.

Centaurus A is a nearby example of an extended radio galaxy that features two outer lobes 650,000 and 1,350,000 light-years in diameter. In contrast, compact radio galaxies emit radio lobes not much larger than the galactic nucleus.
Frequently, a compact radio source is found at the center of radio galaxies. In one unusual radio galaxy observed in the mid-1980s, two bright clusters of stars near its center are emitting jets apparently braided together.
