An Apparent Jump in the Radio Position of J1147+3501
The fundamental celestial reference frame is realized by observations of extragalactic radio sources using the technique of very long baseline interferometry (VLBI). Compact... -
On the connection of the apparent proper motion and the VLBI structure of...
Many of the compact extragalactic radio sources that are used as fiducial points to define the celestial reference frame are known to have proper motions detectable with long-...
