Radiogalaxies are galaxies characterized by intense emission of radio waves, primarily produced by relativistic particles in motion along magnetic field lines (known as synchrotron emission). This radio emission is the result of the activity of a supermassive black hole situated at the center of these galaxies, giving rise to a plasma jet that extends over thousands or even millions of
Some galaxies are more than 100 times brighter in the radio wavelengths than the other galaxies, being thus classified as “radio galaxies“. Images at high spatial resolution have shown that the radio emission in these sources arises mainly from two regions, called “radio lobes“, extended hundreds of light years and symmetric with respect to the center of the galaxy. The
