Observational Evidence for a Thick Disk of Dark Molecular Gas in the Outer Galaxy
Michael P. Busch, Philip D. Engelke, Ronald J. Allen +1
We present the serendipitous discovery of an extremely broad ( km/s), faint (), and ubiquitous 1667 and 1665 MHz ground-state thermal OH…

The Structure of Dark Molecular Gas in the Galaxy -- II. Physical State of "CO-Dark" Gas in the Perseus Arm
Michael P. Busch, Ronald J. Allen, Philip D. Engelke +3
We report the results from a new, highly sensitive (mK) survey for thermal OH emission at 1665 and 1667 MHz over a dense, 9 x 9-pixel grid covering a x p…
