Molecular cloud complexes in detail: Interferometric observations of GMCs in M31
N. Neininger
We have accumulated 12CO(1-0) and (2-1) data of several GMCs in M31 using the Plateau de Bure Interferometer. The sample covers a range of 5 to 18 kpc galactocentric distance and v…
Cold dust in the starburst galaxy M82
G. Thuma, N. Neininger, U. Klein +1
The starburst galaxy M82 has been mapped at 1.2 mm using the IRAM 30-m telescope and the MPIfR 19-channel bolometer. The influence of the sidelobe pattern and the 12CO(2-1) line ha…
The High-Resolution OTF Survey of the 12CO in M 31
N. Neininger
We are performing a fully sampled survey of the 12CO(1-0) line emission of the nearby galaxy M 31 with the IRAM 30-m telescope. The resolution obtained is 23" which corresponds to…
Interferometric observations of nearby galaxies
N. Neininger
This contribution presents a short overview about the investigation of the molecular gas content of nearby galaxies using the Plateau de Bure Interferometer. I try to give a rather…
13CO at the centre of M82
N. Neininger, M. Guelin, U. Klein +2
Using the IRAM interferometer, we have observed the nearby starburst galaxy M82 with a 4.2" resolution (~70 pc) in the 1->0 line of 13CO and in the 2.6-mm continuum. The spatial di…
Astronomical detection of the cyanobutadiynyl radical C5N
M. Guelin, N. Neininger, J. Cernicharo
We report the detection of the elusive carbon-chain radical C5N in the dark cloud TMC1 and its tentative detection in the circumstellar envelope IRC+10216. C5N appears to be two or…
