Radio loudness

from Wikipedia, the free encyclopedia

In the case of an astronomical object, the term radio loudness describes the ratio of radio radiation to electromagnetic radiation in other spectral ranges if there is a bimodal distribution . Accordingly, astronomical objects are divided into radio-quiet and radio- loud sources. This classification is used for pulsars as well as all types of active galactic nuclei such as quasars , Seyfert galaxies , BL Lacertae objects and blazars .
