"GASKAP Observations of Cold HI in the Magellanic Stream (Thesis proposal talk)"

The Magellanic Stream (MS) is a low density, metal poor tidal stream of neutral Hydrogen (HI) trailing out behind the Magellanic Clouds. In such an environment we would not expect cold HI to be found, yet cold HI has been observed in the MS. The formation of cold HI is an important step in star formation and the MS replicates conditions in the high red-shift universe, but right on our doorstep. Using the GASKAP HI observations, I will explore how the fraction of cold HI varies in the Magellanic Stream as it reduces in density as it stretches away from the Magellanic Clouds.
