Detection And Chemical Modelling Of Complex Prebiotic Molecule Cyanamide In The Hot Molecular Core G31.41+0.31
In the interstellar medium (ISM), the complex prebiotic molecule cyanamide (NH2CN) plays a key role in producing adenine (C5H5N5), purines (C5H4N4), pyrimidines (C4H4N2), and other biomolecules via a series of […]

Infrared Spectral Signatures of Nucleobases in Interstellar Ices I: Purines
The purine nucleobases adenine and guanine are complex organic molecules that are essential for life. Despite their ubiquitous presence on Earth, purines have yet to be detected in observations of […]
