VLBI Observations of a sample of Palomar-Green quasars II: characterising the parsec-scale radio emission

Ailing Wang, Tao An, Yingkang Zhang +4

This study uses multi-frequency Very Long Baseline Interferometry (VLBI) to study the radio emission from 10 radio-quiet quasars (RQQs) and four radio-loud quasars (RLQs). The dive…
