Total Time Requested: 5 Hours
Proposal Title: HI Self-Absorption study of B5 and L1544
ABSTRACT:
We propose observing atomic hydrogen inside dark clouds through 21 cm self-absorption. The OH (1665 MHz and
1667 MHz) will be observed simultaneously. With highest angular resolution and nest velocity resolution of HI
dark-cloud maps ever achieved, the data set will reveal velocity structure and column density in HI. Combined
with CI maps from SWAS, we will exam the eect of the UV eld throughout the region and the implications of
PDR models.
