Searching for cold gas in the Magellanic Stream

Recent GALFA-HI mapping of the tip of the Magellanic Stream showed evidence for the existence of the multi-phase medium in this interacting tail of gas. To constrain temperature of the cool gas component, we propose sensitive HI absorption measurements against 10 radio continuum sources behind the Stream. Only one temperature measurement of the Stream gas close to the Magellanic Clouds exists since a few weeks ago (Matthews et al.). Arecibo can achieve much better sensitivity and is perfectly suited for such measurements.
