How is the energy that powers radio galaxies quasars? How is the energy that powers radio galaxies, quasars, and other active galactic nuclei thought to be produced? By gravity, which converts the potential energy of matter falling toward a central black hole into kinetic energy, which is then converted to thermal energy by collisions among the particles of matter.
What do quasars and radio galaxies have in common? All of the Active Galaxies (Seyferts, Radio Galaxies, Blazars, Quasars) have properties in common: bright nuclei and rapid variability.
How is the energy that powers active galactic nuclei produced? The observed energy is generated as matter accretes onto a supermassive black hole with a mass millions or even billions of times that of the Sun. The accreting matter can outshine the rest of the galaxy as it is heated in very high-speed collisions outside the black hole’s event horizon.
Why do quasars emit radio waves? The radio radiation from quasars is in the form of synchrotron radiation, which is when a charged particle enters a magnetic field, moves around the lines of force, speeds up close to the speed of light, and radiates energy.
