Fundamental differences in the radio properties of red and blue quasars: enhanced compact AGN emission in red quasars

open access: yes
We have recently used the Faint Images of the Radio Sky at Twenty-centimeters (FIRST) survey to show that red quasars have fundamentally different radio properties to typical blue quasars: a significant (factor ≈3) enhancement in the radio-detection ...

The radio emission in radio-quiet quasars: the VLBA perspective

open access: yesMonthly Notices of the Royal Astronomical Society, 2023
ABSTRACT The origin of the radio emission in radio-quiet quasars (RQQ) is not established yet. We present new VLBA observations at 1.6 and 4.9 GHz of 10 RQQ (9 detected), which together with published earlier observations of 8 RQQ (5 detected), forms a representative sample of 18 RQQ drawn from the Palomar–Green sample of low z (<

Radio emission from radio-quiet quasars

Nature, 1980
In a search for radio emission from bright, optically selected quasars, we detected ∼50% of the quasars at 5 GHz. This radio detection rate is so much higher than that for faint quasars (
