The relationship between the radio core-dominance parameter and spectral index in different classes of extragalactic radio sources (II)

ZY Pei, JH Fan, D Bastieri, U Sawangwit… - … in Astronomy and …, 2019 - iopscience.iop.org
Active galactic nuclei (AGNs) can be divided into two major classes, namely radio-loud and
radio-quiet AGNs. A small subset of the radio-loud AGNs is called blazars, which are …
