Optical/IR counterpart to the resolved X-ray jet source CXO J172337.5-373442 and its distance
Bhaswati Mookerjea, Pietro Parisi, Sudip Bhattacharyya +3
We present results of observations in the optical to mid-infrared wavelengths of the X-ray source CXO J172337.5-373442, which was serendipitously discovered in the Chandra images a…
Gas morphology and energetics at the surface of PDRs: new insights with Herschel observations of NGC 7023
C. Joblin, P. Pilleri, J. Montillaud +37
We investigate the physics and chemistry of the gas and dust in dense photon-dominated regions (PDRs), along with their dependence on the illuminating UV field. Using Herschel-HIFI…
The origin of the [C II] emission in the S140 PDRs - new insights from HIFI
C. Dedes, M. Röllig, B. Mookerjea +38
Using Herschel's HIFI instrument we have observed [C II] along a cut through S140 and high-J transitions of CO and HCO+ at two positions on the cut, corresponding to the externally…
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 observations in the ultracompact HII region Mon R2: Water in dense Photon-dominated regions (PDRs)
A. Fuente, O. Berne, J. Cernicharo +42
Mon R2, at a distance of 830 pc, is the only ultracompact HII region (UC HII) where the photon-dominated region (PDR) between the ionized gas and the molecular cloud can be resolve…
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…
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…
Detection of interstellar oxidaniumyl: abundant H2O+ towards the star-forming regions DR21, Sgr B2, and NGC6334
V. Ossenkopf, H. S. P. Müller, D. C. Lis +99
We identify a prominent absorption feature at 1115 GHz, detected in first HIFI spectra towards high-mass star-forming regions, and interpret its astrophysical origin. The character…
