2) A starbust galaxy like M82 drives a strong galactic wind made up of matter leaving the galaxy. Which events inside the galaxy drive these winds? Where does the energy come from that powers these winds?
The bursts of star formation have produced dramatic effects on M82. A collective out gassing of stellar winds from thousands of new stars and supernova driven shock fronts has caused the ejection of ultra-hot gases (mostly hydrogen and nitrogen at temperatures of several million degrees) which extend out from the galactic core some several thousand light years. The superheated gases which arise from the combined particle winds of ...
