Sulphur-bearing species are often used to probe the physical structure of star-forming
regions of the interstellar medium, but the chemistry of sulphur in these regions is still poorly …

We report the detection of the sulfur-bearing species NCS, HCCS, H 2 CCS, H 2 CCCS, and
C 4 S for the first time in space. These molecules were found towards TMC-1 through the …

Context. N-methylformamide, CH 3 NHCHO, may be an important molecule for interstellar
pre-biotic chemistry because it contains a peptide bond, which in terrestrial chemistry is …

The detection of complex organic molecules (COMs) toward cold sources such as pre-stellar
cores (with T< 10 K) has challenged our understanding of the formation processes of COMs …

Context. Detailed astrochemical models are a key component to interpret the observations of
interstellar and circumstellar molecules since they allow important physical properties of the …

An exhaustive chemical characterization of dense cores is mandatory to our understanding
of chemical composition changes from a starless to a protostellar stage. However, only a few …

We report the detection of the oxygen-bearing complex organic molecules propenal (C 2 H 3
CHO), vinyl alcohol (C 2 H 3 OH), methyl formate (HCOOCH 3), and dimethyl ether (CH 3 …

Using the Yebes 40m and IRAM 30m radio telescopes, we detected a series of harmonically
related lines with a rotational constant B 0= 4460.590±0.001 MHz and a distortion constant …

We report the detection, for the first time in space, of cyano thioformaldehyde (HCSCN) and
propynethial (HCSCCH) towards the starless core TMC-1. Cyano thioformaldehyde presents …

The gas-phase reaction networks are the backbone of astrochemical models. However, due
to their complexity and nonlinear impact on the astrochemical modeling, they can be the first …
