The Giant Molecular Cloud associated with RCW 106 A 1 . 2 mm continuum mapping study
We have mapped the dust continuum emission from the molecular cloud covering a region of 28 pc×94 pc associated with the well-known H region RCW 106 at 1.2 mm using SIMBA on SEST. The observations, having an HPBW of 24′′ (0.4 pc), reveal 95 clumps, of which about 50% have MSX associations and only 20% have IRAS associations. Owing to the higher sensitivity to colder dust and higher angular r...
متن کاملDust Emission from the Perseus Molecular Cloud
Using far-infrared emission maps taken by IRAS and Spitzer and a near-infrared extinction map derived from 2MASS data, we have made dust temperature and column density maps of the Perseus molecular cloud. We show that the emission from transiently heated very small grains (VSGs) and the big grain dust emissivity vary as a function of extinction and dust temperature, with higher dust emissivitie...
متن کاملCold dust and molecular line emission
In this paper we present new observations of the interstellar medium in the non-interacting edge-on galaxy NGC5907. We have observed the J = 2 − 1 and J = 1 − 0 lines of the 12CO molecule and radio continuum emission at λ 1.2mm. The distribution of the molecular gas (as traced by CO) shows amaximum in the central region and a ring or spiral armat r ∼ 7 kpc. Further analysis of themajor axis dis...
متن کاملPolarized dust emission of magnetized molecular cloud cores
We compute polarization maps for molecular cloud cores modeled as magnetized singular isothermal toroids, under the assumption that the emitting dust grains are aspherical and aligned with the large-scale magnetic field. We show that, depending on the inclination of the toroid with the line-of-sight, the bending of the magnetic field lines resulting from the need to counteract the inward pull o...
متن کاملThe W51 Giant Molecular Cloud
We present 45-47 angular resolution maps at 50 sampling of the CO and CO J=1-0 emission toward a 1.39 × 1.33 region in the W51 H II region complex. These data permit the spatial and kinematic separation of several spectral features observed along the line of sight to W51, and establish the presence of a massive (1.2 × 10 M⊙), large (∆l × ∆b = 83pc × 114 pc) giant molecular cloud (GMC), defined ...
