The tentative detection of 3-hydroxypropanal (HO(CH)C(O)H) toward the Galactic center molecular cloud G+0.693-0.027 prompts a systematic survey in this source aimed at dete…
The Emergence of Prebiotic Chemistry in the ISM
Izaskun Jimenez-Serra, Giuliana Cosentino, Francisco Montenegro-Montes +22
Contrary to popular belief, the interstellar medium (ISM) is not empty; it is filled with atoms, dust particles, and molecules. Some of these molecules may have been the very build…
The role of supernova remnants for the emergence of pre-biotic chemistry in molecular clouds
Giuliana Cosentino, Izaskun Jiménez-Serra, Laura Colzi +11
There is growing evidence that the Sun might have formed within a nebula impacted by at least one SNR. In this scenario, ejecta and shocks from SNRs may have provided the elements…
Laboratory Detection and Rotational Spectroscopy of -HNSO: Implications for Astronomical Observations
