Spectra of Nearby Galaxies Measured with a New Very Broadband Receiver
Gopal Narayanan, Ronald L. Snell, Neal R. Erickson +4
Three-millimeter-wavelength spectra of a number of nearby galaxies have been obtained at the Five College Radio Astronomy Observatory (FCRAO) using a new, very broadband receiver.…
The Molecular Properties of Galactic HII Regions
L. D. Anderson, T. M. Bania, J. M. Jackson +5
We derive the molecular properties for a sample of 301 Galactic HII regions including 123 ultra compact (UC), 105 compact, and 73 diffuse nebulae. We analyze all sources within the…
Re-examining Larson's Scaling Relationships in Galactic Molecular Clouds
Mark Heyer, Coleman Krawczyk, Julia Duval +1
The properties of Galactic molecular clouds tabulated by Solomon etal (1987) (SRBY) are re-examined using the Boston University-FCRAO Galactic Ring Survey of 13CO J=1-0 emission. T…
The Five College Radio Astronomy Observatory CO Mapping Survey of the Taurus Molecular Cloud
Gopal Narayanan, Mark H. Heyer, Christopher Brunt +3
The FCRAO Survey of the Taurus Molecular Cloud observed the 12CO and 13CO J=1-0 emission from 98 square degrees of this important, nearby star forming region. This set of data with…
Large-Scale Structure of the Molecular Gas in Taurus Revealed by High Linear Dynamic Range Spectral Line Mapping
Paul F. Goldsmith, Mark Heyer, Gopal Narayanan +3
We report the results of a 100 square degree survey of the Taurus Molecular Cloud region in the J = 1-0 transition of 12CO and 13CO. The image of the cloud in each velocity channel…
Magnetically Aligned Velocity Anisotropy in the Taurus Molecular Cloud
Mark Heyer, Hao Gong, Eve Ostriker +1
Velocity anisotropy induced by MHD turbulence is investigated using computational simulations and molecular line observations of the Taurus molecular cloud. A new analysis method i…
