THE MAGELLANIC STREAM: BREAK-UP and ACCRETION onto the HOT GALACTIC CORONA
The Magellanic H i Stream (≈2 × 109 Mo [d/55 kpc]2) encircling the Galaxy at a distance d is arguably the most important tracer of what happens to gas accreting onto a disk galaxy. Recent observations reveal that the Stream's mass is in fact dominated (3:1) by its ionized component. Here we revisit the origin of the mysterious Hα recombination emission observed along much of its length that is overly bright (∼150-200 mR) for the known Galactic ultraviolet (UV) background (≈20-40 mR [d/55...[Show more]
