TRACING DENSE and DIFFUSE NEUTRAL HYDROGEN in the HALO of the MILKY WAY
Moss, V.A.; Lockman, Felix J.; McClure-Griffiths, Naomi
We have combined observations of Galactic high-velocity H i from two surveys: a very sensitive survey from the Green Bank 140 ft Telescope with limited sky coverage, and the less sensitive but complete Galactic All Sky Survey from the 64 m Parkes Radio Telescope. The two surveys preferentially detect different forms of neutral gas due to their sensitivity. We adopt a machine learning approach to divide our data into two populations that separate across a range in column density: (1) a narrow...[Show more]
