Signatures of inflow motion in cores of massive star formation: Potential collapse candidates
Yuefang Wu, Christian Henkel, Rui Xue +2
Using the IRAM 30 m telescope, a mapping survey in optically thick and thin lines was performed towards 46 high mass star-forming regions. The sample includes UC H{\sc ii} precurso…
Formaldehyde Densitometry of Starburst Galaxies
Jeffrey G. Mangum, Jeremy Darling, Karl M. Menten +1
With a goal toward deriving the physical conditions in external galaxies, we present a survey of the formaldehyde emission in a sample of starburst systems. By extending a techniqu…
The innermost region of the water megamaser radio galaxy 3C403
A. Tarchi, A. Brunthaler, C. Henkel +3
The standard unified scheme of active galactic nuclei requires the presence of high column densities of gas and dust potentially obscuring the central engine. So far, few direct su…
Galactic Edge Clouds I: Molecular Line Observations and Chemical Modelling of Edge Cloud 2
P. M. E. Ruffle, T. J. Millar, H. Roberts +5
Edge Cloud 2 (EC2) is a molecular cloud, about 35 pc in size, with one of the largest galactocentric distances known to exist in the Milky Way. We present observations of a peak CO…
Redshifted formaldehyde from the gravitational lens B0218+357
N. Jethava, C. Henkel, K. M. Menten +2
The gravitational lens toward B0218+357 offers the unique possibility to study cool moderately dense gas with high sensitivity and angular resolution in a cloud that existed half a…
How do methanol masers manage to appear in the youngest star vicinities and isolated molecular clumps?
A. M. Sobolev, D. M. Cragg, S. P. Ellingsen +10
General characteristics of methanol (CH3OH) maser emission are summarized. It is shown that methanol maser sources are concentrated in the spiral arms. Most of the methanol maser s…
