The Milky Way in Molecular Clouds: A New Complete CO Survey
- T. Dame, D. Hartmann, P. Thaddeus
- Physics
- 13 September 2000
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…
EGRET Observations of the Diffuse Gamma-Ray Emission from the Galactic Plane
- S. Hunter, D. Bertsch, D. Thompson
- Physics
- 1 May 1993
The high-energy diffuse gamma-ray emission from the Galactic plane, |b| ≤ 10°, is studied using observations from the Energetic Gamma-Ray Experiment Telescope (EGRET) on the Compton Gamma-Ray…
A Composite CO survey of the entire Milky Way
- T. Dame, H. Ungerechts, P. Thaddeus
- Physics
- 1 November 1987
Large-scale CO surveys of the entire Galactic plane and specific nearby clouds have been combined to produce a panorama of the entire Milky Way in molecular clouds at an angular resolution of 1/2°.…
The largest molecular cloud complexes in the first galactic quadrant
- T. Dame, B. Elmegreen, R. Cohen, P. Thaddeus
- Physics
- 1 June 1986
The CO emission within a few kiloparsecs of the Sun is dominated by a small number of very large molecular complexes, including those associated with the Orion Nebula (Thaddeus 1982), M16 and M17…
A uniform CO survey of the molecular clouds in Orion and Monoceros
- B. Wilson, T. Dame, M. Masheder, P. Thaddeus
- Physics
- 3 November 2004
We report the results of a new large scale survey of the Orion-Monoceros complex of molecular clouds made in the J = 1 → 0 line of 12 CO with the Harvard-Smithsonian 1.2 m millimetre-wave telescope.…
Diffuse gamma-ray emission in the Galactic plane from cosmic-ray, matter, and photon interactions
- D. Bertsch, T. Dame, P. Thaddeus
- Physics
- 1 October 1993
On the basis of the spatial distribution, intensity, and energy spectrum, the diffuse Galactic high-energy gamma radiation is believed to be the result of cosmic-ray interactions with matter, and to…
A CO survey of the southern Milky Way - The mean radial distribution of molecular clouds within the solar circle
- L. Bronfman, R. Cohen, H. Alvarez, J. May, P. Thaddeus
- Physics
- 1988
The large system of molecular clouds in Orion and Monoceros
- R. Maddalena, J. Moscowitz, P. Thaddeus, M. Morris
- Environmental Science, Physics
- 1 April 1986
Emission is noted over about one-eighth of an 850-sq deg region centered on Orion and Monoceros that has been surveyed in the J = 1 to 0 line of CO; most of the emission arises from giant molecular…
A New Spiral Arm of the Galaxy: The Far 3 kpc Arm
- T. Dame, P. Thaddeus
- Physics
- 10 July 2008
We report the detection in CO of the far-side counterpart of the well-known expanding 3 kpc arm in the central region of the Galaxy. In a CO longitude-velocity map at b = 0° the far 3 kpc arm can be…
Molecular Clouds and Star Formation in the Inner Galaxy: A Comparison of CO, H ii, and Far-Infrared Surveys
Surveys of the galactic plane over galactic latitudes from -1 degree to +1 degree and galactic longitudes from 12 degrees to 60 degrees are compared in the CO line at 2.6 mm, in the far-infrared…
