| Abstract |
From its new vantage point at CTIO, the Wisconsin Ha Mapper is poised to
explore the full distribution and kinematics of diffuse plasma in
extended gaseous structures near the Magellanic Clouds. Shaped by the
interaction between the Clouds and the Milky Way, the Bridge, Stream,
and Leading Arm gas complexes have been studied extensively in 21 cm
emission and optical/UV absorption. With spectral resolution of 12 km/s,
WHAM is able to separate optical emission from these structures and
brighter local gas near vLSR 0 km/s. Combined with its
unprecedented sensitivity to the limit of atmospheric line confusion (
10s of mR), we are embarking on a survey of the ionized component of the
Magellanic System with WHAM. With observations of the southern component
of our all-sky survey nearly completed, we have begun to examine some
emission features toward the Magellanic System. Here we present a sample
of several regions observed recently with WHAM in Ha. WHAM was built and
continues to operate with ongoing support from NSF. The research
presented here is currently funded by award AST-0607512 and an
International Program Development Fund from the University of Sydney. |
