Centrosymmetric molecules as possible carriers of diffuse interstellar bands
M. Kazmierczak, M. R. Schmidt, G. A. Galazutdinov +3
In this paper, we present new data with interstellar C2 (Phillips bands A-X), from observations made with the Ultraviolet-Visual Echelle Spectrograph of the European Southern Obser…
Excitation temperature of C2 and broadening of the 6196A diffuse interstellar band
M. Kazmierczak, P. Gnacinski, M. R. Schmidt +3
This paper presents a finding of the correlation between the width of a strong diffuse interstellar band at 6196A and the excitation temperature of C2 based on high resolution and…
Abundances and rotational temperatures of the C2 interstellar molecule towards six reddened early-type stars
M. Kazmierczak, M. R. Schmidt, A. Bondar +1
Using high-resolution (~85000) and high signal-to-noise ratio (~200) optical spectra acquired with the European Southern Observatory Ultraviolet and Visual Echelle Spectrograph, we…
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 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…
Interstellar OH+, H2O+ and H3O+ along the sight-line to G10.6-0.4
Maryvonne Gerin, M. De Luca, John Black +50
We report the detection of absorption lines by the reactive ions OH+, H2O+ and H3O+ along the line of sight to the submillimeter continuum source G10.60.4 (W31C). We used the He…
Strong absorption by interstellar hydrogen fluoride: Herschel/HIFI observations of the sight-line to G10.6-0.4 (W31C)
D. A. Neufeld, P. Sonnentrucker, T. G. Phillips +45
We report the detection of strong absorption by interstellar hydrogen fluoride along the sight-line to the submillimeter continuum source G10.6-0.4 (W31C). We have used Herschel's…
