Cold HI ejected into the Magellanic Stream


We report the direct detection of cold HI gas in a cloud ejected from the Small Magellanic Cloud (SMC) towards the Magellanic Stream. The cloud is part of a fragmented shell of HI gas on the outskirts of the SMC. This is the second direct detection of cold HI associated with the Magellanic Stream using absorption. The cold gas was detected using 2... more

C3297 - Follow-up observations of HI absorption near the SMC detected by ASKAP


How does dense, cold gas form in the outskirts of galaxies where the gas thins out? In this project we will explore that question, following up on hints of cold neutral hydrogen which showed up in early results from the new ASKAP telescope. We will examine locations surrounding the Small Magellanic Cloud where gas is in the process of being strippe... more
