New large-scale CO surveys of the first and second Galactic quadrants and the nearby molecular cloud complexes in Orion and Taurus, obtained with the CfA 1.2 m telescope, have been combined with 31 other surveys obtained over the past two decades with that instrument and a similar telescope on Cerro Tololo in Chile, to produce a new composite CO survey of the entire Milky Way. The survey consists of 488,000 spectra that Nyquist or beamwidth ( °) sample the entire Galactic plane over a strip 4… Expand

A Uniform Catalog of Molecular Clouds in the Milky Way
The all-Galaxy CO survey of Dame, Hartmann, & Thaddeus (2001) is by far the most uniform, large-scale Galactic CO survey. Using a dendrogram-based decomposition of this survey, we present a catalogExpand
RESOLVED MEASUREMENTS OF X CO IN NGC 6946
We present the largest sample to date of giant molecular clouds (GMCs) in a substantial spiral galaxy other than the Milky Way. We map the distribution of molecular gas with high resolution and imageExpand
A High-Latitude Molecular Structure in Pegasus-Pisces
We detected CO emission from a shell-like or ringlike dust structure approximately 20° across centered near Galactic coordinates (l = 105°, b = -45°). This region was also observed in CO by YamamotoExpand
Molecular Clouds in the Milky Way
In the past twenty years, the reconnaissance of 12 CO and 13 CO emission in the Milky Way by single-dish millimeter-wave telescopes has expanded our view and understanding of interstellar molecularExpand
A Herschel (C II) Galactic plane survey II. CO-dark H2 in clouds
Context. H i and CO large scale surveys of the Milky Way trace the diffuse atomic clouds and the dense shielded regions of molecular hydrogen clouds, respectively. However, until recently, we haveExpand
Comparative analysis of molecular clouds in M31, M33, and the Milky Way
We present BIMA observations of a 2' field in the northeastern spiral arm of M31. In this region we find six giant molecular clouds (GMCs) that have a mean diameter of 57 ± 13 pc, a mean velocityExpand
ATLASGAL - Ammonia observations towards the southern Galactic Plane
The initial conditions of molecular clumps in which high-mass stars form are poorly understood. In particular, a more detailed study of the earliest evolutionary phases is needed. The APEX TelescopeExpand
Large scale IRAM 30 m CO-observations in the giant molecular cloud complex W43
We aim to give a full description of the distribution and location of dense molecular clouds in the giant molecular cloud complex W43. It has previously been identified as one of the most massiveExpand
High-resolution molecular gas maps of M33
New observations of CO (J = 1 → 0) line emission from M33, using the 25 element BEARS focal plane array at the Nobeyama Radio Observatory 45 m telescope, in conjunction with existing maps from theExpand
A CO survey on a sample of Herschel cold clumps
The physical state of cold cloud clumps has a great impact on the process and efficiency of star formation and the masses of the forming stars inside these objects. The sub-millimetre survey of theExpand
