The search for complex molecules in the ISM: a complete 3 mm line survey of Sgr B2-N and -M
A. Belloche, C. Comito, C. Hieret +3
Famous for the extraordinary richness of its molecular content, the Sgr B2 molecular cloud complex is the prime target in the long-standing search for ever more complex species. We…
Massive Infrared-Quiet Dense Cores: Unveiling the Initial Conditions of High-Mass Star Formation
Frédérique Motte, S. Bontemps, N. Schneider +2
As Pr. Th. Henning said at the conference, cold precursors of high-mass stars are now "hot topics". We here propose some observational criteria to identify massive infrared-quiet d…
Hot Cores in the submm - obscured by dust?
Rainer Rolffs, Peter Schilke, Claudia Comito +2
We present APEX observations of HCN (9-8) and (4-3) lines toward a sample of hot cores. The spectral shapes of the main transitions are asymmetric and self-absorbed, as expected fo…
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…
The earliest phases of high-mass star formation: a 3 square degree millimeter continuum mapping of Cygnus X
Frédérique Motte, S. Bontemps, P. Schilke +3
We have made an extensive 1.2mm continuum mosaicing study of the Cygnus X molecular cloud complex using the MAMBO cameras at the IRAM 30 m telescope. We then compared our mm maps w…
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…
