Galactic Nonthermal Continuum Emission,s occurring at the subsolar point. These inferences were sharply revised when, after an entire year of observation, it was found that the direction to the disturbance was not correlated with the position of the Sun, but rather referred to a fixed direction in space.

Extragalactic Neutral Hydrogen,echniques of spectral line aperture synthesis, developed especially at Cambridge, Green Bank, and Owens Valley, bloomed in full maturity at Westerbork and more recently at the VLA. The contributions of single-dish instruments have, however, remained important, especially for survey-oriented projects

Supernova Remnants,ynthesize heavy elements, and inject energy into the interstellar medium which can maintain turbulent cloud motions, heat a large fraction of the volume of the galaxy, and accelerate particles. Supernova remnants with their shock waves can also generate cosmic rays and compress clouds, perhaps starting another cycle of star formation.
