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…
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…
Long-term observations of Uranus and Neptune at 90 GHz with the IRAM 30m telescope - (1985 -- 2005)
C. Kramer, R. Moreno, A. Greve
The planets Uranus and Neptune with small apparent diameters are primary calibration standards. We investigate their variability at ~90 GHz using archived data taken at the IRAM 30…
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…
A complete 12CO 2-1 map of M51 with HERA
C. Kramer, M. Hitschfeld, K. F. Schuster +2
The nearby, almost face-on, and interacting galaxy M51 offers an excellent opportunity to study the distribution of molecular gas and the mechanisms governing the star formation ra…
A complete 12CO 2-1 map of M51 with HERA: I. Radial averages of CO, HI, and radio continuum
K. F. Schuster, C. Kramer, M. Hitschfeld +2
The mechanisms governing the star formation rate in spiral galaxies are not yet clear. The nearby, almost face-on, and interacting galaxy M51 offers an excellent opportunity to stu…
