UV resistance of nucleosides -- an experimental approach
Max Winkler, Barbara M. Giuliano, Paola Caselli
The emergence of life on Earth is a highly discussed but still unsolved question. Current research underlines the importance of environments within close proximity to the Earth's s…
Extensive ro-vibrational analysis of deuterated-cyanoacetylene (DCN) from millimeter-wavelengths to the infrared domain
M. Melosso, L. Bizzocchi, A. Adamczyk +12
Cyanoacetylene, the simplest cyanopolyyne, is an abundant interstellar molecule commonly observed in a vast variety of astronomical sources. Despite its importance as a potential t…
First detection of NHD and ND in the interstellar medium
M. Melosso, L. Bizzocchi, O. Sipilä +7
Deuterium fractionation processes in the interstellar medium (ISM) have been shown to be highly efficient in the family of nitrogen hydrides. To date, observations were limited to…
Submillimetre and far-infrared spectroscopy of monodeuterated amidogen radical (NHD): improved rest-frequencies for astrophysical observations
Luca Bizzocchi, Mattia Melosso, Barbara Michela Giuliano +6
Observations of ammonia in interstellar environments have revealed high levels of deuteration, and all its D-containing variants, including ND, have been detected in cold prest…
Propargylimine in the laboratory and in space: millimetre-wave spectroscopy and first detection in the ISM
Luca Bizzocchi, Domenico Prudenzano, Victor M. Rivilla +10
Small imines containing up to three carbon atoms are present in the interstellar medium. As alkynyl compounds are abundant in this medium, propargylimine thus represents a promisin…
Gas phase Elemental abundances in Molecular cloudS (GEMS). II. On the quest for the sulphur reservoir in molecular clouds: the case
