OH in Messier 82
M. K. Argo, A. Pedlar, T. W. B. Muxlow +4
Several new main line OH masers have been detected in the nearby starburst galaxy M82. Eight masers have been detected to 5 sigma, six of which are new detections. Observations cov…
Gas properties in the Medusa minor merger - comparing with ULIRGs
S. Aalto, S. Huttemeister, F. Walter
High resolution observations of CO and 13CO 1--0 in the Medusa (NGC4194) minor merger show the CO/13CO 1--0 intensity ratio (R) increasing from normal values (5-10) in the outer pa…
Gas Properties in the Starburst Centers of Barred Galaxies
S. Huettemeister, S. Aalto
The physical properties of molecular gas can be deduced from the analysis of line intensity ratios, most commonly of the CO isotopomers 12CO and 13CO. Barred galaxies, especially t…
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…
The discovery of a gas-rich bar in UGC 2855: A galaxy in a pre-starburst phase?
S. Huettemeister, S. Aalto, W. F. Wall
We present the first interferometric CO observations of the barred late-type galaxy UGC2855 and its companion UGC2866. UGC2855 is shown to belong to the rare class of galaxies with…
