Synergy of multifrequency studies from observations of NGC6334I

Andreas Seifahrt, Sven Thorwirth, Henrik Beuther +5

We combine multifrequency observations from the millimeter to near infrared wavelengths that demonstrate the spatial distributions of H2, CO, and NH3 emission, which are all manife…

High mass star formation in the IRAS 17233-3606 region: a new nearby and bright hot core in the southern sky

S. Leurini, C. Hieret, S. Thorwirth +5

We present molecular line observations of the massive star forming region IRAS 17233-3606 aimed at studying the molecular core associated with the source. The observations were mad…

Detection of amino acetonitrile in Sgr B2(N)

A. Belloche, K. M. Menten, C. Comito +5

Amino acids are building blocks of proteins and therefore key ingredients for the origin of life. The simplest amino acid, glycine, has long been searched for in the interstellar m…

New ammonia masers towards NGC6334I

A. J. Walsh, S. N. Longmore, S. Thorwirth +2

We report the detection of new ammonia masers in the non-metastable (8,6) and (11,9) transitions towards the massive star forming region NGC6334I. Observations were made with the A…

A multi-transition submillimeter water maser study of evolved stars - detection of a new line near 475 GHz

K. M. Menten, A. Lundgren, A. Belloche +2

Context: Maser emission from the H2O molecule probes the warm, inner circumstellar envelopes of oxygen-rich red giant and supergiant stars. Multi-maser transition studies can be us…

Millimeter wave spectral line surveys and line mapping studies of NGC6334I and I(N)

S. Thorwirth, A. J. Walsh, F. Wyrowski +8

NGC6334I and I(N) have been observed with the Swedish-ESO Submillimetre Telescope, SEST, at wavelengths of 3, 2, and 1.3 mm. Especially NGC6334 I shows rich emission from many diff…

APEX survey of southern high mass star forming regions

C. Hieret, S. Leurini, K. M. Menten +3

A systematic study of a large sample of sources, covering a wide range in galactocentric distances, masses and luminosities, is a fast and efficient way of obtaining a good overvie…

Revealing the environs of the remarkable southern hot core G327.3-0.6

F. Wyrowski, K. M. Menten, P. Schilke +3

We present a submm study of the massive hot core G327.3-0.6 that constrains its physical parameters and environment. The APEX telescope was used to image CO and N2H+ emission, to o…

Submillimeter spectroscopy of southern hot cores: NGC6334(I) and G327.3-0.6

P. Schilke, C. Comito, S. Thorwirth +5

High-mass star-forming regions are known to have a rich molecular spectrum from many species. Some of the very highly excited lines are emitted from very hot and dense gas close to…

Discovery of Interstellar CF+

D. A. Neufeld, P. Schilke, K. M. Menten +7

We discuss the first astronomical detection of the CF+ (fluoromethylidynium) ion, obtained by observations of the J=1-0 (102.6 GHz), J=2-1 (205.2 GHz) and J=3-2 (307.7 GHz) rotatio…
