Toward a Trigonometric Parallax of Sgr A*
Published online by Cambridge University Press: 12 April 2016
Abstract
We initiated a project with the VLBA to measure directly the distance to the Galactic Center, R0, via a trigonometric parallax. Here we describe the observing program and the first results–direct imaging of the effects of the Sun’s orbit about the Galactic Center.
