Organic molecules in interstellar space: Latest advances
M Guélin, J Cernicharo - Frontiers in Astronomy and Space Sciences, 2022 - frontiersin.org
Although first considered as too diluted for the formation of molecules in-situ and too harsh
an environment for their survival, the interstellar medium has turned out to host a rich palette …

Pure hydrocarbon cycles in TMC-1: Discovery of ethynyl cyclopropenylidene, cyclopentadiene, and indene
We report the detection for the first time in space of three new pure hydrocarbon cycles in
TMC-1: cC 3 HCCH (ethynyl cyclopropenylidene), cC 5 H 6 (cyclopentadiene), and cC 9 H 8 …

Discovery of benzyne, o-C6H4, in TMC-1 with the QUIJOTE line survey
We report the detection, for the first time in space, of a new non-functionalised hydrocarbon
cycle in the direction of TMC-1: oC 6 H 4 (ortho-benzyne). We derive a column density for …

First glycine isomer detected in the interstellar medium: glycolamide (NH2C (O) CH2OH)
We report the first detection in the interstellar medium (ISM) of a C 2 H 5 O 2 N isomer: syn-
glycolamide (NH 2 C (O) CH 2 OH). The exquisite sensitivity at sub-mK levels of an …

From the laboratory to the interstellar medium: A strategy to search for exotic molecules in space
The chemistry of the interstellar medium occurs under extreme conditions and can lead to
the formation of exotic molecules. These are species that on Earth are unstable and/or …
