How does a galaxy become a radio galaxy?
Quick Answer
A supermassive black hole at the center can launch powerful jets that accelerate particles and emit strong radio waves. These jets can stretch far beyond the visible galaxy.
The Full Story
Some galaxies host active galactic nuclei powered by gas falling onto a central supermassive black hole. Magnetic fields and rapidly rotating material can channel some of that energy into jets that shoot out at near-light speed. The charged particles in those jets produce synchrotron radiation, which is bright at radio wavelengths. Famous examples include Cygnus A and Centaurus A. Radio galaxies are important because they show how black holes can influence star formation and gas across entire galaxies.
