A peculiar HI cloud near the distant globular cluster Pal 4
Jacco Th. van Loon, Snezana Stanimirovic, Mary Putman +4
We present 21-cm observations of four Galactic globular clusters, as part of the on-going GALFA-HI Survey at Arecibo. We discovered a peculiar HI cloud in the vicinity of the dista…
Mapping Hydrogen in the Galaxy, Galactic Halo, and Local Group with ALFA: The GALFA-HI Survey Starting with TOGS
S. J. Gibson, K. A. Douglas, C. Heiles +4
Radio observations of gas in the Milky Way and Local Group are vital for understanding how galaxies function as systems. The unique sensitivity of Arecibo's 305m dish, coupled with…
Cold HI in Turbulent Eddies and Galactic Spiral Shocks
Steven J. Gibson, A. Russell Taylor, Jeroen M. Stil +3
HI 21cm-line self-absorption (HISA) reveals the shape and distribution of cold atomic clouds in the Galactic disk. Many of these clouds lack corresponding CO emission, despite bein…
CO in HI Self-Absorbed Clouds in Perseus
P. D. Klaassen, R. Plume, S. J. Gibson +2
We have observed 12CO J = 2-1 and J = 1-0, and 13CO J = 1-0 emission in two regions of HI Self-Absorption (HISA) in Perseus: a small, isolated HISA feature called the globule and a…
An Automated Method for the Detection and Extraction of HI Self-Absorption in High-Resolution 21cm Line Surveys
Steven J. Gibson, A. Russell Taylor, Lloyd A. Higgs +2
We describe algorithms that detect 21cm line HI self-absorption (HISA) in large data sets and extract it for analysis. Our search method identifies HISA as spatially and spectrally…
A Self-Absorption Census of Cold HI Clouds in the Canadian Galactic Plane Survey
Steven J. Gibson, A. Russell Taylor, Lloyd A. Higgs +2
We present a 21cm line HI self-absorption (HISA) survey of cold atomic gas within Galactic longitudes 75 to 146 degrees and latitudes -3 to +5 degrees. We identify HISA as spatiall…
