Herschel observations of interstellar chloroni

Using the Herschel Space Observatory's Heterodyne Instrument for the Far-Infrared, we have observed para-chloronium (H2Cl+) toward six sources in the Galaxy. We detected interstellar chloronium absorption in foreground molecular clouds along the sight lines to the bright submillimeter continuum sources Sgr A (+50 km s–1 cloud) and W31C. Both the para-H35 2Cl+ and para-H37 2Cl+ isotopologues ...

Herschel observations of interstellar chloronium (2012 .

Using the Herschel Space Observatory's Heterodyne Instrument for the Far-Infrared, we have observed parachloronium (H2Cl+) toward six sources in the Galaxy. We detected interstellar chloronium absorption in foreground molecular clouds along the sight lines to the bright submillimeter continuum sources Sgr A (+50 km s(-1) cloud) and W31C.

Herschel/HIFI discovery of interstellar chloronium (H2Cl

We report the first detection of chloronium, H2Cl+, in the interstellar medium, using the HIFI instrument aboard the Herschel Space Observatory. The 212–101 lines of ortho-HCl+ and ortho-HCl+ are d ...

Das "Herschel Space Observatory" (nach dem Entdecker der Infrarotstrahlung Wilhelm Herschel) ist ein 3,4 Tonnen schweres, von der ESA entwickeltes Weltraumteleskop, das im Mai 2009 gestartet wurde.

Herschel/HIFI discovery of interstellar chloronium (H2Cl .

However, the observed H2Cl+ column densities, in excess of 10(13) cm(-2), are significantly higher than the model predictions. Our observations demonstrate the outstanding spectroscopic capabilities of HIFI for detecting new interstellar molecules and providing key constraints for astrochemical models. Publication

Herschel Observations of Interstellar Chloronium .

Using the Herschel Space Observatory's Heterodyne Instrument for the Far-Infrared, we have observed para-chloronium (H_(2)Cl^+) toward six sources in the Galaxy. We detected interstellar chloronium absorption in foreground molecular clouds along the sight lines to the bright submillimeter continuum sources Sgr A (+50 km s^(–1) cloud) and W31C.

A HERSCHEL/HIFI LEGACY SURVEY OF HF AND H2O IN THE GALAXY .

We combine Herschel observations for a total of 12 sources to construct the most uniform survey of HF and H 2 O in our Galactic disk. Both molecules are detected in absorption along all sight lines. The high spectral resolution of the Heterodyne Instrument for the Far-infrared (HIFI) allows us to compare the HF and H 2 O distributions in 47 diffuse cloud components sampling the disk.

Herschel/HIFI line surveys: Discovery of interstellar .

Prior to the launch of Herschel, HCl was the only chlorine-containing molecule detected in the interstellar medium (ISM). However, chemical models have identified chloronium, H_2Cl^+, as a relatively abundant species that is potentially detectable. H_2Cl^+ was predicted to be most abundant in the environments where the ultraviolet radiation is strong: in diffuse clouds, or near the surfaces of ...

H2Cl+ in the I

The absorption features near 485.4 and 780.05 GHz were both affected by emission features from dimethyl ether. A preliminary model for this molecule permitted accounting for these emmsion features in the analyses. This is a clear example that features by so-called "weed" species can affect "flowers" even in the case of Herschel observations.

HERSCHEL OBSERVATIONS OF INTERSTELLAR CHLORONIUM. II .

In this paper, we report new Herschel/HIFI observations of interstellar chloronium. We have targeted the transition of ortho-H 2 Cl + near 781 GHz, which presents a larger optical depth than either of the 485 or 189 GHz transitions observed previously.
