The Cologne Database for Molecular Spectroscopy, CDMS: a useful tool for astronomers and spectroscopists
The general features of the internet browser-accessible Cologne Database for Molecular Spectroscopy (CDMS) and recent developments in the CDMS are described in the present article. The databaseExpand
The Herschel-Heterodyne Instrument for the Far-Infrared (HIFI)
The Heterodyne Instrument for the Far-Infrared (HIFI) is a single sky-pixel, high-resolution (>300.000), spectrometer for ESA's Herschel Space Observatory. The instrument is designed to provide aExpand
A new view of the Cygnus X region - KOSMA $\mathsf{^{13}}$CO 2 $\to$ 1, 3 $\to$ 2, and $\mathsf{^{12}}$CO 3 $\to$ 2 imaging
Context. The Cygnus X region is one of the richest star formation sites in the Galaxy. There is a long-standing discussion about whether the region is a chance superposition of several complexesExpand
High spatial resolution isotopic CO and CS observations of M17 SW - The clumpy structure of the molecular cloud core
This paper presents high-angular-resolution maps of the M17 SW cloud core in the C(O-18) J = 2-1 (13 arcsec FWHM beam) and C(S-34) J = 2-1 (27 arcsec FWHM), 3-2 (17 arcsec FWHM) lines obtained withExpand
The Orion Molecular Cloud and Star-Forming Region
La structure du nuage moleculaire geant Orion, sa compostion stellaire, l'interaction entre les etoiles OB de Orion A et le nuage, et la region de formation stellaire BN-IRc 2 sont etudiees. DeExpand
A photon dominated region code comparison study
Aims. We present a comparison between independent computer codes, modeling the physics and chemistry of interstellar photon dominated regions (PDRs). Our goal was to understand the mutual differencesExpand
In-orbit performance of Herschel-HIFI
Aims. In this paper the calibration and in-orbit performance of the Heterodyne Instrument for the Far-Infrared (HIFI) is described. Methods. The calibration of HIFI is based on a combination ofExpand
Aperture synthesis observations of the circumnuclear ring in the Galactic center
Aperture synthesis observations with the Hat Creek millimeter-wave interferometer have been used to study the circumnuclear neutral gas ring in the Galactic center at high spatial and spectralExpand
Anatomy of the Photodissociation Region in the Orion Bar
The results strongly support the theoretical models and show conclusively that the incident far-ultraviolet radiation field, not shocks as has sometimes been proposed, is responsible for the emission in the Orion Bar. Expand
Quantification of molecular cloud structure using the Delta -variance
We present a detailed study of the Δ -variance as a method to quantify molecular cloud structure. The Δ -variance was introduced by Stutzki et al. (1998) to analyze the drift behaviour of scalarExpand
