THE TRIGONOMETRIC PARALLAX OF CYGNUS X-1

THE TRIGONOMETRIC PARALLAX OF CYGNUS X-1

We report a direct and accurate measurement of the distance to the X-ray binary Cygnus X-1, which contains the first black hole to be discovered. The distance of 1.86[superscript +0.12] [subscript – 0.11] kpc was obtained from a trigonometric parallax measurement using the Very Long Baseline Array....
