Position and Proper Motion of Sagittarius A* in the ICRF3 Frame from VLBI Absolute Astrometry
Sagittarius A* (Sgr A*) is a strong, compact radio source believed to be powered by a supermassive black hole at the galactic center. Extinction by dust and gas in the galactic plane prevents observing it optically, but its position and proper motion have previously been estimated using radio interf...
