The Galactic Centre G+0.633-0.0604 Molecular Cloud: A New Astrochemical Gold Mine. I. Gas Physical Properties
astrobiology.com/2026/07/10/… #astrobiology #astrochemistry
🚨✨ MEET G+0.633-0.0604
A new shock-dominated molecular cloud at the southern edge of Sgr B2.
G+0.633 emerges as a promising new laboratory for astrochemistry and star formation, and as the southern counterpart of the famous G+0.693 cloud!
arxiv.org/abs/2607.01481
🧵👇
The paper is already available in arXiv at arxiv.org/abs/2607.01481, soon to be published in Open Access in @AandA_journal.
Many thanks to @L_Colzi, @ryvendel, @MiguelSanzNovo, S. Martín, I. Jiménez-Serra and S. Zeng for contributing into it!

This review confirms that stereoisomerism is a fundamental contributor to interstellar molecular complexity.
It is already available in arXiv: arxiv.org/abs/2603.24848 ;
and it will appear soon in Open Access in the ACS Earth and Space Chemistry journal (@ACSPublications) (🧵4/4)

We have discussed the mechanisms that can explain the stereoisomeric ratios (OSR) - defined as the column density ratio of the higher-energy isomer divided by that of the lower-energy isomer (🧵3/4 ).

"INTERSTELLAR STEREOISOMERISM”: stereoisomers are molecules that share the same bonding arrangement, but differ in the three-dimensional orientation of their atoms. These are the 16 stereoisomeric pairs detected in the interstellar medium so far (🧵2/4 ):

🚨 NEW PUBLICATION 🚨
"INTERSTELLAR STEREOISOMERISM”: In this review done with @MiguelSanzNovo and @DavidSAstro99
we present the first comprehensive overview of stereoisomerism in the interstellar medium. @C_Astrobiologia
