Variations in the Star Formation Efficiency of the Dense Molecular Gas across the Disks of Star-Forming Galaxies
(2015-10)
We present a new survey of HCN(1-0) emission, a tracer of dense molecular gas, focused on the little-explored regime of normal star-forming galaxy disks. Combining HCN, CO, and infrared (IR) emission, we investigate the ...
Low CO luminosities in dwarf galaxies
(2012-05-07)
We present maps of (12)COJ = 2-1 emission covering the entire star-forming disks of 16 nearby dwarf galaxies observed by the IRAM HERACLES survey. The data have 13 '' angular resolution, similar to 250 pc at our average ...
H I in galactic disks
(Cambridge University Press, 2009)
Studies of the atomic phase of the interstellar medium, via the 21-cm spectral line of neutral hydrogen (H I), play a key role in our attempts to understand the structure and evolution of disk galaxies. We present here ...
