Reconstructing Deconstruction: High-Velocity Cloud Distance Through Disruption Morphology
J. E. G. Peek, M. E. Putman, Christopher F. McKee +2
We present Arecibo L-band Feed Array 21-cm observations of a sub-complex of HVCs at the tip of the Anti-Center Complex. These observations show morphological details that point to…
Properties of the thinnest cold HI clouds in the diffuse interstellar medium
Snezana Stanimirovic, Carl Heiles, Nissim Kanekar
We have obtained deep HI observations in the direction of 22 continuum sources without previously detected cold neutral medium (CNM). 18 CNM clouds were detected with the typical H…
A Cold Nearby Cloud Inside the Local Bubble
David M. Meyer, J. T. Lauroesch, Carl Heiles +2
The high-latitude Galactic H I cloud toward the extragalactic radio source 3C 225 is characterized by very narrow 21 cm emission and absorption indicative of a very low H I spin te…
The Warp and Spiral Arms of the Milky Way
E. S. Levine, Leo Blitz, Carl Heiles +1
We examine the outer Galactic HI disk for deviations from the b=0 plane by constructing maps of disk surface density, mean height, and thickness. We find that the Galactic warp is…
First results from the Arecibo Galactic HI Survey: the disk/halo interface region in the outer Galaxy
Snezana Stanimirovic, Mary Putman, Carl Heiles +11
The consortium for Galactic studies with the Arecibo L-band Feed Array (ALFA) is conducting a neutral hydrogen (HI) survey of the whole Arecibo sky (declination range from -1 to 38…
The Spiral Structure of the Outer Milky Way in Hydrogen
E. S. Levine, Leo Blitz, Carl Heiles
We produce a detailed map of the perturbed surface density of neutral hydrogen in the outer Milky Way disk demonstrating that the Galaxy is a non-axisymmetric multi-armed spiral. S…
