galactic spur
Definición
- One of the largest coherent structures in the radio sky, projecting from the Galactic plane at Galactic longitude l ~ 20° and extending to a very high Galactic latitude b ~ +80°. It was first identified in low frequency radio surveys in the 1950s. The spur is also prominent in soft X-rays. Its origins and nature have long been debated. However, what causes this phenomena is not well understood. It may be due to a combination of OB associations and supernova explosions.
