| Historically, the connection between radio loud and radio quiet quasars has been unclear, but new studies are pointing
toward a similarity in the physical mechanisms of core radio emission in the two classes. Both classes appear to
have similar core spectral index distributions, including or inverted cores in RQQs, both have compact VLBI
cores, and both appear to be about equally time-variable. This suggests that RQQs possess beamed, relativistic jets
like those in RLQs. If RQQs are really lower power cousins of RLQs, the jets in RQQs should show superluminal
motions. With the advent of very high sensitivity VLBI using the High Sensitivity Array, it should now be possible
to detect the parsec-scale jets in RQQs and measure component speeds. This project will search for jets in 9 excellent
candidate RQQs. Five were granted time in BB191, and time is requested for the remaining four in this proposal. For
those sources having signi cant secondary components, we will propose follow-up multi-epoch imaging to determine
component speeds for comparison with the properties of RLQs. |
