Starbursts Arise Differently in Dwarf Galaxy Mergers

10 August 2017

My latest paper “A Widespread, Clumpy Starburst in the Isolated Ongoing Dwarf Galaxy Merger dm1647+21” has been accepted for publication in the Astrophysical Journal. In this paper we present optical integral-field spectroscopy which shows a distributed starburst in a merger of a pair of dwarf galaxies. We argue this suggests that dwarf galaxy mergers trigger starbursts though large-scale ISM compression rather than funneling of gas to the nuclei (as happens in massive galaxies). A preprint is available.

Update (01 September 2017): The article is now published in ApJ.
