Spitzer spectral line mapping of protostellar outflows: I. Basic data and outflow energetics
David A. Neufeld, Brunella Nisini, Teresa Giannini +7
We report the results of spectroscopic mapping observations carried out toward protostellar outflows in the BHR71, L1157, L1448, NGC 2071, and VLA 1623 molecular regions using the…
On the robustness of the ammonia thermometer
Sebastien Maret, Alexandre Faure, Emanuele Scifoni +1
Ammonia inversion lines are often used as probes of the physical conditions in the dense ISM. The excitation temperature between the first two para metastable (rotational) levels i…
Spitzer mapping of molecular hydrogen pure rotational lines in NGC 1333: A detailed study of feedback in star formation
Sebastien Maret, Edwin A. Bergin, David A. Neufeld +10
We present mid-infrared spectral maps of the NGC 1333 star forming region, obtained with the the Infrared Spectrometer on board the Spitzer Space Telescope. Eight pure H2 rotationa…
