Astrochemical Pathways to Complex Organic and Prebiotic Molecules: Experimental Perspectives for In Situ Solid-State Studies

Life, 2021
A deep understanding of the origin of life requires the physical, chemical, and biological study of prebiotic systems and the comprehension of the mechanisms underlying their evolutionary steps.

The distribution of complex organic molecules in Barnard 5

Astronomy & Astrophysics
Complex organic molecules (COMs) are prevalent in cold and dense molecular cloud environments and are formed by a combination of gas phase and grain surface chemical reactions.

Complex Organic Molecules in Protostars with ALMA Spectral Surveys (COMPASS)

Astronomy & Astrophysics
Context. It remains a fundamental research question in astrochemistry to characterize the inventory of complex organic molecules formed during the early stages of star formation, which may affect the eventual chemical composition of protoplanetary disks ...

A High-level Ab Initio Study of the Destruction of Methanimine under UV Radiation

The Astrophysical Journal, 2023
The photodecomposition of methanimine (CH _2 NH) in the interstellar medium through several possible pathways is investigated by means of high-level multireference configuration interaction ab initio calculations.

The SKA as a Prebiotic Molecule Detector

Frontiers in Astronomy and Space Sciences, 2022
One of the theories for the origin of life proposes that a significant fraction of prebiotic material could have arrived to Earth from outer space between 4.1 and 3.8 billion years ago.

The Detection of Hot Molecular Cores in the Small Magellanic Cloud

The Astrophysical Journal Letters, 2023
We report the first detection of hot molecular cores in the Small Magellanic Cloud (SMC), a nearby dwarf galaxy with 0.2 solar metallicity. We observed two high-mass young stellar objects in the SMC with the Atacama Large Millimeter/submillimeter Array ...

Toward Accurate Formation Routes of Complex Organic Molecules in the Interstellar Medium: The Paradigmatic Cases of Acrylonitrile and Cyanomethanimine

Frontiers in Astronomy and Space Sciences, 2022
The investigation of reaction mechanisms in the interstellar medium requires the evaluation of reaction rates and branching ratios, which can be effectively obtained in the framework of the ab-initio transition state/master equation formalism.

The Robust Detection and Spatial Distribution of Acetaldehyde in Orion KL: Atacama Large Millimeter/submillimeter Array Observations and Chemical Modeling

The Astrophysical Journal
Despite the organic molecule inventory detected in the Orion Kleinmann–Low Nebula (Orion KL), acetaldehyde (CH _3 CHO)—one of the most ubiquitous interstellar aldehydes—has not been firmly identified with millimeter-wave interferometry.
