Although first considered as too diluted for the formation of molecules in-situ and too harsh
an environment for their survival, the interstellar medium has turned out to host a rich palette …

To date, 204 individual molecular species, comprised of 16 different elements, have been
detected in the interstellar and circumstellar medium by astronomical observations. These …

To date, 241 individual molecular species, composed of 19 different elements, have been
detected in the interstellar and circumstellar medium by astronomical observations. These …

Context. Yebes 40 m radio telescope is the main and largest observing instrument at Yebes
Observatory and is devoted to very long baseline interferometry (VLBI) and single-dish …

We report the first detection in the interstellar medium (ISM) of the Z-isomer of
cyanomethanimine (HNCHCN), an HCN dimer proposed as precursor of adenine. We …

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 …

Context. Vacuum-ultraviolet (VUV) photons are important drivers of chemical processes in
space. Thus, it is important to accurately characterize and constrain photorates in different …

Abstract Peptide bonds (N–C= O) play a key role in metabolic processes since they link
amino acids into peptide chains or proteins. Recently, several molecules containing peptide …

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 …
