Carriers of 4964 and 6196 diffuse interstellar bands and environments dominated by either CH or CH molecules
T. Weselak, G. A. Galazutdinov, O. Sergeev +3
The analysis of radial velocities of interstellar spectral features: CH, CH as well as 4964 and 6196 diffuse interstellar bands, seen in spectra of HD 151932 and 152233, sugg…
Nitrogen hydrides in interstellar gas: Herschel/HIFI observations towards G10.6-0.4 (W31C)
C. M. Persson, J. H. Black, J. Cernicharo +49
The HIFI instrument on board the Herschel Space Observatory has been used to observe interstellar nitrogen hydrides along the sight-line towards G10.6-0.4 in order to improve our u…
Detection of hydrogen fluoride absorption in diffuse molecular clouds with Herschel/HIFI: a ubiquitous tracer of molecular gas
P. Sonnentrucker, D. A. Neufeld, T. G. Phillips +47
We discuss the detection of absorption by interstellar hydrogen fluoride (HF) along the sight line to the submillimeter continuum sources W49N and W51. We have used Herschel's HIFI…
Herschel/HIFI measurements of the ortho/para ratio in water towards Sagittarius B2(M) and W31C
D. C. Lis, T. G. Phillips, P. F. Goldsmith +74
We present Herschel/HIFI observations of the fundamental rotational transitions of ortho- and para-HO and HO in absorption towards Sagittarius~B2(M) and W31C. The…
Herschel/HIFI observations of interstellar OH+ and H2O+ towards W49N: a probe of diffuse clouds with a small molecular fraction
D. A. Neufeld, J. R. Goicoechea, P. Sonnentrucker +50
We report the detection of absorption by interstellar hydroxyl cations and water cations, along the sight-line to the bright continuum source W49N. We have used Herschel's HIFI ins…
Excitation and Abundance of C3 in star forming cores:Herschel/HIFI observations of the sight-lines to W31C and W49N
B. Mookerjea, T. Giesen, J. Stutzki +47
We present spectrally resolved observations of triatomic carbon (C3) in several ro-vibrational transitions between the vibrational ground state and the low-energy nu2 bending mode…
