Discovery of the interstellar chiral molecule propylene oxide (CH3CHCH2O)
TLDR
Propylene oxide is detected in the gas phase in a cold, extended molecular shell around the embedded, massive protostellar clusters in the Sagittarius B2 star-forming region, representative of the earliest stage of solar system evolution in which a chiral molecule has been found. Expand
2018 Census of Interstellar, Circumstellar, Extragalactic, Protoplanetary Disk, and Exoplanetary Molecules
To date, 204 individual molecular species, comprised of 16 different elements, have been detected in the interstellar and circumstellar medium by astronomical observations. These molecules range inExpand
HERSCHEL OBSERVATIONS OF EXTRAORDINARY SOURCES: ANALYSIS OF THE HIFI 1.2 THz WIDE SPECTRAL SURVEY TOWARD ORION KL. I. METHODS ∗
We present a comprehensive analysis of a broadband spectral line survey of the Orion Kleinmann-Low nebula (Orion KL), one of the most chemically rich regions in the Galaxy, using the HIFI instrumentExpand
HERSCHEL OBSERVATIONS OF EXTRAORDINARY SOURCES: ANALYSIS OF THE FULL HERSCHEL/HIFI MOLECULAR LINE SURVEY OF SAGITTARIUS B2(N) ∗
A sensitive broadband molecular line survey of the Sagittarius B2(N) star-forming region has been obtained with the Heterodyne Instrument for the Far-Infrared (HIFI) instrument on the Herschel SpaceExpand
Observational Results of a Multi-telescope Campaign in Search of Interstellar Urea [(NH2)2CO]
In this paper, we present the results of an observational search for gas phase urea [(NH_2)_2CO] observed toward the Sgr B2(N-LMH) region. We show data covering urea transitions from ~100 GHz to 250Expand
Detection of the aromatic molecule benzonitrile (c-C6H5CN) in the interstellar medium
TLDR
The discovery of benzonitrile (c-C6H5CN), one of the simplest nitrogen-bearing aromatic molecules, in the interstellar medium is presented, providing a chemical link to the carriers of the unidentified infrared bands. Expand
A SEARCH FOR HYDROXYLAMINE (NH2OH) TOWARD SELECT ASTRONOMICAL SOURCES
Observations of 14 rotational transitions of hydroxylamine (NH_2OH) using the NRAO 12 m telescope on Kitt Peak are reported toward IRC+10216, Orion KL, Orion S, Sgr B2(N), Sgr B2(OH), W3IRS5, andExpand
Nuclear spin dependence of the reaction of H(3)+ with H2. II. Experimental measurements.
TLDR
Multipass infrared direct absorption spectroscopy has been employed to monitor the populations of several low-energy rotational levels of ortho- and para-H(3)(+) in hydrogenic plasmas of varying para- H(2) (p-H (2)) enrichment. Expand
ALMA Detection of Interstellar Methoxymethanol (CH 3 OCH 2 OH)
We report the detection of interstellar methoxymethanol (CH3OCH2OH) in Atacama Large Millimeter/submillimeter Array (ALMA) Bands. 6 and. 7 toward the MM1 core in the high-mass star-forming region NGCExpand
A Search for l-C_3H^+ and l-C_3H in Sgr B2(N), Sgr B2(OH), and the Dark Cloud TMC-1
Pety et al. (2012) recently reported the detection of several transitions of an unknown carrier in the Horsehead PDR and attribute them to l-C_3H^+. Here, we have tested the predictive power ofExpand
