Detection of a four-carbon sugar in interstellar space
Izaskun Jimenez-Serra, Juan Garcia de la Concepcion, Herma M. Cuppen +19
Sugars are essential biomolecules, serving as metabolic fuels, nucleic acid backbone components, and structural or energy-storage polymers. A central question in origin-of-life res…
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…
Spectral survey of the diffuse gas toward BL Lac in the Q band
Maryvonne Gerin, Harvey Liszt, Belen Tercero +1
The chemical composition of diffuse interstellar clouds is not fully established. They host an active chemistry despite their relatively low density and the ubiquitous presence of…
Discovery of interstellar phenalene (-CH): A new piece for the chemical puzzle of PAHs in space
Carlos Cabezas, Marcelino Agúndez, Cristóbal Pérez +10
We present the discovery of the unsubstituted polycyclic aromatic hydrocarbon (PAH) phenalene (-CH) in TMC-1 as part of the QUIJOTE line survey. In spite of the lo…
Detection of the linear SiC and SiC radicals in IRC\,+10216
José Cernicharo, Juan Ramón Pardo, Marcelino Agúndez +6
We detected the linear radicals SiC and SiC toward IRC+10216 using an ultrasensitive line survey gathered with the Yebes 40\,m radio telescope. The derived column…
On the abiotic origin of dimethyl sulfide: discovery of DMS in the Interstellar Medium
Miguel Sanz-Novo, VÃctor M. Rivilla, Christian P. Endres +14
Following the discovery of dimethyl sulfide (CHSCH, DMS) signatures in comet 67P/Churyumov-Gerasimenko, we report the first detection of this organosulfur species in the in…
