The Redshift Search Receiver 3 mm Wavelength Spectra of 10 Galaxies
Ronald L. Snell, Gopal Narayanan, Min S. Yun +5
The 3 mm wavelength spectra of 10 galaxies have been obtained at the Five College Radio Astronomy Observatory using a new, very broadband receiver and spectrometer, called the Reds…
Chemical Variation in Molecular Cloud Cores in the Orion A Cloud
Ken'ichi Tatematsu, Tomoya Hirota, Ryo Kandori +1
We have observed molecular cloud cores in the Orion A giant molecular cloud (GMC) in CCS, HC3N, DNC, and HN13C to study their chemical characteristics. We have detected CCS in the…
Physical Properties and Galactic Distribution of Molecular Clouds identified in the Galactic Ring Survey
Julia Roman-Duval, James M. Jackson, Mark Heyer +2
We derive the physical properties of 580 molecular clouds based on their 12CO and 13CO line emission detected in the University of Massachusetts-Stony Brook (UMSB) and Galactic Rin…
The Star Formation Rate and Gas Surface Density Relation in the Milky Way: Implications for Extragalactic Studies
Amanda Heiderman, Neal J. Evans, Lori E. Allen +2
We investigate the relation between star formation rate (SFR) and gas surface densities in Galactic star forming regions using a sample of YSOs and massive clumps. Our YSO sample c…
