The Influence of the Starburst on the ISM in NGC 1569
S. Muehle, S. Huettemeister, U. Klein +1
A tremendous starburst, that ended about 4 million years ago, has had a very strong impact on the dwarf galaxy NGC 1569. Evidence for this event is still prominent in the different…
Conversion Problems: How (Not) to Determine Molecular Masses in Dwarf Galaxies
S. Huettemeister
The determination of molecular gas masses in star forming dwarf irregular galaxies is crucial to assess the star formation process in these objects. But the derivation of the molec…
Changing Molecular Gas Properties in the Bar and Canter of NGC7479
S. Huettemeister, S. Aalto, M. Das +1
We present sensitive interferometric 12CO, 13CO and HCN observations of the barred spiral galaxy NGC7479, known to be one of the few barred galaxies with a continuous gas-filled ba…
Complex molecular gas structure in the Medusa merger
S. Aalto, S. Huettemeister
High resolution OVRO aperture synthesis maps of the 12CO 1-0 emission in the `Medusa' galaxy merger (NGC4194) reveal the molecular emission being surprisingly extended. It is distr…
Non-equilibrium H2 ortho-to-para ratio in two molecular clouds of the Galactic Center
N. J. Rodriguez-Fernandez, J. Martin-Pintado, P. de Vicente +4
We present ISO observations of the S(0), S(1), S(2), and S(3) rotational lines of molecular hydrogen from two molecular clouds near the Galactic Center (GC). We have also measured…
Giant Molecular Clouds in the Dwarf Galaxy NGC1569
C. L. Taylor, S. Huettemeister, U. Klein +1
We present CO (1-0) and (2-1) observations of the dwarf starburst galaxy NGC 1569 with the IRAM interferometer on Plateau de Bure. We find the CO emission is not spatially associat…
