[132.01] Tracking the Magellanic Stream(s)

D.L. Nidever, S.R. Majewski (UVa), W.B. Burton (NRAO)

We use the Leiden-Argentine-Bonn (LAB) all-sky HI survey to explore the HI Magellanic Stream. An automated Gaussian analysis program was run on the southern sky for b<-20 degrees and the results give the clearest picture of the Magellanic Stream to date. While we also find that the Magellanic Stream is composed of two primary filaments, as first indicated by Putman et al. (2003), with a LAB velocity precision of 1 km/s we are able to track the two filaments all of the way from their origin in the Magellanic Clouds to their endpoint 100 degrees away. One of the filaments is found to eminate from the 30 Dor region of the LMC. The filaments provide a new tool to study the dynamics of the Magellanic Clouds.
