Astrometric Apparent Motion of High-redshift Radio Sources

Astrometric Apparent Motion of High-redshift Radio Sources

Radio-loud quasars at high redshift ( z ≥ 4) are rare objects in the universe and rarely observed with Very Long Baseline Interferometry (VLBI). But some of them have flux density sufficiently high for monitoring of their apparent position. The instability of the astrometric positions could be linke...
