12CO 4-3 and [CI] 1-0 at the centers of NGC 4945 and Circinus
M. Hitschfeld, M. Aravena, C. Kramer +30
Studying molecular gas in the central regions of the star burst galaxies NGC4945 and Circinus enables us to characterize the physical conditions and compare them to previous local…
The molecular environment of the massive star forming region NGC 2024: Multi CO transition analysis
M. Emprechtinger, M. C. Wiedner, R. Simon +10
NGC 2024, a sites of massive star formation, have complex internal structures caused by cal heating by young stars, outflows, and stellar winds. These complex cloud structures lead…
Photon Dominated Regions in NGC 3603
M. Röllig, C. Kramer, C. Rajbahak +32
Aims: We aim at deriving the excitation conditions of the interstellar gas as well as the local FUV intensities in the molecular cloud surrounding NGC 3603 to get a coherent pictur…
Clumpy photon-dominated regions in Carina. I. [CI] and mid-J CO lines in two 4'x4' fields
C. Kramer, M. Cubick, M. Roellig +31
The Carina region is an excellent astrophysical laboratory for studying the feedback mechanisms of newly born, very massive stars within their natal giant molecular clouds (GMCs) a…
First observations with CONDOR, a 1.5 THz heterodyne receiver
M. C. Wiedner, G. Wieching, F. Bielau +15
The THz atmospheric windows centered at roughly 1.3 and 1.5~THz, contain numerous spectral lines of astronomical importance, including three high-J CO lines, the N+ line at 205 mic…
Submillimeter Line Emission from LMC N159W: a Dense, Clumpy PDR in a Low Metallicity Environment
J. L. Pineda, N. Mizuno, J. Stutzki +30
Star formation at earlier cosmological times takes place in an interstellar medium with low metallicity. The Large Magellanic Cloud (LMC) is ideally suited to study star formation…
