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…

The Photon Dominated Region in the IC 348 molecular cloud

K. Sun, V. Ossenkopf, C. Kramer +4

In this paper we discuss the physical conditions of clumpy nature in the IC 348 molecular cloud. We combine new observations of fully sampled maps in [C I] at 492 GHz and 12CO 4--3…

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…

A clumpy-cloud PDR model of the global far-infrared line emission of the Milky Way

M. Cubick, J. Stutzki, V. Ossenkopf +2

The fractal structure of the interstellar medium suggests that the interaction of UV radiation with the ISM as described in the context of photon-dominated regions (PDR) dominates…

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…
