A Universe Full of Radio Galaxies

A Universe Full of Radio Galaxies

Radio galaxies are a subclass of active galactic nuclei (AGN) and, in most cases, display what is known as a “core-jet-lobe” morphology. A supermassive black hole, accreting matter at the galaxy’s core, launches material out at the poles, forming two jets of highly energetic particles. These jets can travel immense distances before spreading out into massive, radio-emitting lobes. The structure of these galaxies and their environments will give astronomers clues into how they form stars throughout the history of the universe. Millions of radio sources will be imaged with the Very Large Array Sky Survey (VLASS). By taking this extragalactic census, a statistically significant population will begin to form. An ambitious radio survey like VLASS provides the astronomical community with a crucial piece of the puzzle in the electromagnetic spectrum, comparing data to the ultraviolet, optical, infrared, and sub-millimeter. Coordinates for this celestial object are: 09h 36m 01.7s -32d 37m 22.6s.
