From local chemistry to galactic evolution: unlocking the power of interstellar isotopes with ALMA2040

Laura Colzi, Hayley A. Bunn, Víctor M. Rivilla +29

Molecular isotopic ratios provide a unique window into the chemical evolution of the interstellar medium, linking stellar nucleosynthesis and Galactic chemical evolution to the phy…

Tracing the sulfur depletion in starless and pre-stellar cores

L. Schöller, S. Spezzano, O. Sipilä +4

Sulfur is one of the most abundant elements in the Universe, yet the sulfur budget inferred from the observed sulfur-bearing molecules in dense cores is significantly lower than ex…

High Resolution Overtone Spectroscopy of HNC $^{+}$ and HCN $^{+}$

Miguel Jiménez-Redondo, Chiara Schleif, Julianna Palotás +5

Rotationally resolved spectra of the HNC $^{+}$ and HCN $^{+}$ molecular ions have been recorded in the spectral range between 6200 and 6800 \rcm\ using a cryogenic ion trap instrument.…

High deuteration of methanol in L1544

S. Spezzano, W. Riedel, P. Caselli +7

Isotopic fractionation is a very powerful tool to follow the evolution of material from one stage to the next in the star-formation process. Pre-stellar cores exhibit some of the h…

Near-infrared high resolution overtone spectroscopy of the hydronium ion H $_{3}$ O $^{+}$ : the $2 ν_{3}^{2 +}$ and $2 ν_{3}^{2 -}$ bands

Chiara Schleif, Hayley A. Bunn, Miguel Jiménez-Redondo +2

This work presents the rovibrational spectra of the two strongest first overtone bands of the asymmetric stretching mode $ν_{3}$ ( $2 ν_{3}^{2 +}$ and $2 ν_{3}^{2 -}$ ) of the hydronium ion, H…

Laboratory rotational spectroscopy leads to the first interstellar detection of singly deuterated methyl mercaptan (CH $_{2}$ DSH)

Hayley A. Bunn, Silvia Spezzano, Laurent H. Coudert +8

We report an extensive rotational spectroscopic analysis of singly deuterated methyl mercaptan (CH $_{2}$ DSH) using both millimeter and far-infrared synchrotron spectra to achieve a…

Advancing spectroscopic understanding of HOCS $^{+}$ : Laboratory investigations and astronomical implications

Valerio Lattanzi, Miguel Sanz-Novo, Víctor M. Rivilla +5

Sulphur-bearing species play crucial roles in interstellar chemistry, yet their precise characterisation remains challenging. Here, we present laboratory experiments aimed at exten…
