(astronomy) An outflow of highly energetic radiation and material from a starburst galaxy.

Example Sentences

New data is presented that indicate that strong far infrared galaxies commonly have largescale emission line nebulae whose properties are suggestive of mass outflows (superwinds), presumably driven by the high supernova rate associated with the central starburst.

Using the VLA at 6 and 2—cm the authors searched for radio continuum emission in a list of OH/IR stars with such an asymmetric OH maser emission. No detections were made, and the authors conclude that these stars are still in the superwind phase and that the OH asymmetry is caused by envelope asymmetries and not by the presence of an ionized core.
