Starbursts are regions of enhanced star formation efficiency, where gas is being converted into stars at much higher rates than can be sustained over billions of years. ... A nice example in the southern sky is the nearby galaxy NGC 7552, which was imaged with the Compact Array at 3 cm by Forbes et al. ...
