Radio galaxies emit radio waves from their central core. The energy to
produce these emissions is generated by a supermassive black hole, which
sends out jets of high-energy particles many millions of
light-years into intergalactic space. These particles emit radio
waves, which we can use to trace the jets and determine how much
energy they contain. Many of the images on these pages are Double Radio Sources
Associated with Galactic Nuclei (DRAGNs), which are large-scale double
radio sources produced by that
are launched by processes in AGN.
