Extended Radio Source

Cygnus-x is an extended radio source centered at δ=40° and R.A. = 20h25m (l=48°, b=0°). Its emission in the continuous spectrum has been studied by Davies using high resolution surveys at the following frequencies: 92, 158, and 1425 Mcps, 242, 400, 600, and 900 Mcps. The background emission at the position of the source was removed by a smooth interpolation in galactic longitude between the two sides of the source. The resultant flux density did not change significantly with frequency and had the value 4.5 X 10−23 wm2 (cps)−1. Moreover, the brightness temperature Ts of the center of the source varied inversely as the square of the frequency v; Ts·v2 had the value 3.5X1019 °K sec−2.
