In cold molecular clouds, submillimetre emission lines are excited by the ambient radiation field. The pumping is dominated by the cosmic microwave background (CMB). It is usual in molecular line radiative transfer modelling to assume simply that this is the only incident radiation field. In this paper, a molecular line transport code and a dust radiative transfer code are used to explore the effects of the inclusion of a full interstellar radiation field (ISRF) on a simple test molecular cloud… Expand

Molecular Emission Line Formation in Prestellar Cores
We investigate general aspects of molecular line formation under conditions typical of prestellar cores. Focusing on simple linear molecules, we study the formation of their rotational lines withExpand
First Evidence for Molecular Interfaces between Outflows and Ambient Clouds in High-Mass Star-forming Regions?
We present new observations of the Cep A East region of massive star formation and describe an extended and dynamically distinct feature not previously recognized. This feature is present in emissionExpand
The origin of the molecular emission around the southern hemisphere Re 4 IRS – HH 188 region
Aims. We present SEST observations of the molecular environment ahead of the southern Herbig-Haro object 188 (HH 188), associated with the low-mass protostar Re 4 IRS. We have also used theExpand
Infall Signatures in a Prestellar Core Embedded in the High-mass 70 μm Dark IRDC G331.372-00.116
Using Galactic Plane surveys, we have selected a massive (1200 M$_\odot$), cold (14 K) 3.6-70 $\mu$m dark IRDC G331.372-00.116. This IRDC has the potential to form high-mass stars and, given theExpand
Hot cores: probes of high-redshift galaxies?
The very high rates of second generation star formation detected and inferred in high-redshift objects should be accompanied by intense millimetre-wave emission from hot core molecules. We calculateExpand

Abstract Prestellar cores, by definition, are gravitationally bound but starless pockets of dense gas. Physical conditions that could render a core starless (in the local Universe) is the subject ofExpand


Molecules at High Redshift: The Evolution of the Cool Phase of Protogalactic Disks
We study the formation of molecular hydrogen, after the epoch of reionization, in the context of canonical galaxy formation theory due to hierarchical clustering. There is an initial epoch of H2Expand
Numerical methods for non-LTE line radiative transfer: Performance and convergence characteristics
Comparison is made between a number of independent computer programs for radiative transfer in molecular rota- tional lines. The test models are spherically symmetric circumstellar envelopes with aExpand
Modelling line profiles in infalling cores
Results are presented from a model of molecular line formation in collapsing star-forming cores. The study includes, for the first time, a self-consistent chemical and dynamical model which is thenExpand
Hubble Space Telescope WFPC2 Imaging of M16: Photoevaporation and Emerging Young Stellar Objects
We present Hubble Space Telescope WFPC2 images of elephant trunks in the H II region M16. There are three principle results of this study. First, the morphology and stratified ionization structure ofExpand
Modelling submillimetre spectra of the protostellar infall candidates NGC 1333–IRAS 2 and Serpens SMM4
We present a radiative transfer model, which is applicable to the study of submillimetre spectral line observations of protostellar envelopes. The model uses an exact, non-LTE, spherically symmetricExpand
Photoelectric heating of interstellar gas
Photoelectric emission from interstellar grains is reexamined, and it is argued that some of the assumptions made by other authors lead to an overestimate of the heating rate associated with thisExpand

Molecular gas in the host galaxy of a quasar at redshift z = 6.42
The presence of about 2 × 1010 M[circdot] of H2 in an object at this time demonstrates that molecular gas enriched with heavy elements can be generated rapidly in the youngest galaxies. Expand
Evidence for Protostellar Collapse in B335
We have observed five rotational transitions of H2CO and CS toward the Bok globule, B335, with high spatial and spectral resolution. The characteristic shape of the observed profiles provides direct,Expand
