Scientific paper

High-dynamic range radio observations of Westerlund 1 (Wd 1) are presented that detect a total of 21 stars in the young massive stellar cluster, the richest population of radio emitting stars known for any young massive galactic cluster in the Galaxy. We will discuss some of the more remarkable objects, including the highly radio luminous supergiant B[e] star W9, with an estimated mass-loss rate (˜ 10^{-3} M_&sun; yr^{-1}) comparable to that of η Carina, along with the somewhat unusal detection of thermal emission from almost all the cool red supergiants and yellow hypergiants. There is strong supporting evidence from X-ray observations that each of the WR stars with radio emission are likely to be colliding-wind binaries.
