The Leiden Atomic and Molecular Database (LAMDA) collects spectroscopic information
and collisional rate coefficients for molecules, atoms, and ions of astrophysical and …

Observations that resolve nearby galaxies into individual regions across multiple phases of
the gas–star formation feedback “matter cycle” have provided a sharp new view of molecular …

Context. Isotope abundance ratios provide a powerful tool for tracing stellar nucleosynthesis,
evaluating the composition of stellar ejecta, and constraining the chemical evolution of the …

Context. Gas phase Elemental abundances in molecular CloudS (GEMS) is an IRAM 30-m
Large Program aimed at determining the elemental abundances of carbon (C), oxygen (O) …

Observations of multiple rotational transitions from a single molecule allow for unparalleled
constraints on the physical conditions of the emitting region. We present an analysis of CS in …

GEMS is an IRAM 30 m Large Program whose aim is determining the elemental depletions
and the ionization fraction in a set of prototypical star-forming regions. This paper presents …

We report the detection in TMC-1 of the protonated form of C 3 S. The discovery of the cation
HC 3 S+ was carried through the observation of four harmonically related lines in the Q band …

Context. Sulphur is one of the most abundant elements in the Universe. Surprisingly,
sulphuretted molecules are not as abundant as expected in the interstellar medium and the …

Context. The global context of making numerous data produced by researchers available
requires collecting and organising the data, assigning meaningful metadata, and presenting …

Gas phase Elemental abundances in Molecular CloudS (GEMS) is an IRAM 30 m Large
Program designed to provide estimates of the S, C, N, and O depletions and gas ionization …
