A tale of two isotopes: Spatial variation in HCN fractionation toward young cores
Sigurd S. Jensen, Silvia Spezzano, Olli Sipilä +3
The paper maps H13CN and HC15N in several young starless and pre‑stellar cores, finds that their column density ratio varies spatially and correlates with H2 column density, and sh…
Chemical Complexity in the Early Stages of Star Formation in the SKAO Era
Eleonora Bianchi, Mathilde Bouvier, Claudio Codella +44
About 350 molecules have been identified in the interstellar medium (ISM), including complex molecules relevant to prebiotic chemistry. A remarkable level of molecular diversity ha…
Probing the ion-neutral drift velocity towards the L1544 prestellar core: Detection of ambipolar diffusion using ND and para-NHD
Doris Arzoumanian, Silvia Spezzano, Tommaso Grassi +9
The dynamical role of the magnetic field in the star formation process is tightly linked to the coupling between matter and the field. This coupling is due to the interaction betwe…
A differentiable and optimizable 3D model for interpretation of observed spectral data cubes
T. Grassi, J. E. Pineda, S. Spezzano +6
Molecular spectral cubes of prestellar cores encode the information on the physical and chemical properties of these objects along the line of sight. To retrieve this information,…
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…
Mass Assembly and Chemical Complexity in the Milky Way
Pamela Klaassen, David Eden, Alessio Traficante +13
(Sub-)millimeter spectral lines can be used not only to understand the chemical complexity and enrichment history of an observed portion of our Galaxy, but with spectrally resolved…
