- B. McGuire, P. B. Carroll, G. Blake
- PhysicsScience
- 17 June 2016
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.
A Rigorous Attempt to Verify Interstellar Glycine
In 2003, Kuan and coworkers reported the detection of interstellar glycine (NH2CH2COOH) based on observations of 27 lines in 19 different spectral bands in one or more of the sources Sgr B2(N-LMH),…

A major goal of the Atacama Large Millimeter/submillimeter Array (ALMA) is to make accurate images with resolutions of tens of milliarcseconds, which at submillimeter (submm) wavelengths requires…
Detection of the aromatic molecule benzonitrile (c-C6H5CN) in the interstellar medium
- B. McGuire, A. Burkhardt, M. McCarthy
- Physics, ChemistryScience
- 12 January 2018
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.
