Thermal Pressure in Diffuse H2 Gas Measured by Herschel [C II] Emission and FUSE UV H2 Absorption

Autor: Jorge L. Pineda, T. Velusamy, W. D. Langer, P. F. Goldsmith

UV absorption studies with FUSE have observed H2 molecular gas in translucent and diffuse clouds. Observations of the 158 micron [C II] fine structure line with Herschel also trace the same H2 molecular gas in emission. We present [C II] observations

Autor: J. L. Pineda, Paul F. Goldsmith, W. D. Langer, T. Velusamy, Karen Willacy

Publikováno v: Proceedings of the International Astronomical Union. 8:235-238

We present the results of the distribution of CO-dark H2 gas in a sample of 2223 interstellar clouds in the inner Galaxy (l=−90° to +57°) detected in the velocity resolved [CII] spectra observed in the GOT C+ survey using the Herschel HIFI. We an

Autor: W. D. Langer, Thangasamy Velusamy, Paul F. Goldsmith, Di Li

Publikováno v: The Astrophysical Journal. 715:1370-1382

We report Spitzer Space Telescope observations of the four lowest rotational transitions of H2 in three portions of the boundary of the Taurus molecular cloud. Emission in the two lowest transitions, S(0) and S(1), was detected in almost all pointing

Highly Collimated Jets and Wide-Angle Outflows in HH 46/47: New Evidence from Spitzer Infrared Images

Autor: Thangasamy Velusamy, K. A. Marsh, W. D. Langer

Publikováno v: The Astrophysical Journal. 668:L159-L162

We present new details of the structure and morphology of the jets and outflows in HH46/47 as seen in Spitzer infrared images from IRAC and MIPS, reprocessed using the ``HiRes'' deconvolution technique. HiRes improves the visualization of spatial mor
