Aromatic rings in the Central Molecular Zone: Benzonitrile
V. M. Rivilla, D. San Andrés, M. Sanz-Novo +12
In recent years, several aromatic molecules (benzene-based rings) have been detected in the cold molecular cloud TMC-1, with its CN-derivative, benzonitrile (c-CHCN), also…
Discovery of 1H-cyclopent[cd]indene (c-C11H8) in TMC-1 with the QUIJOTE line survey: A new three-ringed polycyclic aromatic hydrocarbon
R. Fuentetaja, C. Cabezas, M. Agúndez +4
We report the detection of the polycyclic aromatic hydrocarbon (PAH) 1H-cyclopent[cd]indene (c-C11H8) in TMC-1 with the QUI- JOTE line survey. We detected 22 independent lines corr…
Expanding the CHO Isomeric Interstellar Inventory: Discovery of Lactaldehyde and Methoxyacetaldehyde in G+0.693-0.027
M. Sanz-Novo, V. M. Rivilla, I. Jiménez-Serra +17
The tentative detection of 3-hydroxypropanal (HO(CH)C(O)H) toward the Galactic center molecular cloud G+0.693-0.027 prompts a systematic survey in this source aimed at dete…
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…
Analysis of the isotopologues of CS, CCS, CCCS, HCS+, HCCS+, and H2CS in TMC-1 with the QUIJOTE line survey
R. Fuentetaja, C. Cabezas, Y. Endo +7
We performed a detailed analysis of the isotopologues with 13C, 34S, 33S, and 36S of the sulphur-bearing molecules CS, CCS, CCCS,HCS+, HCCS+, and H2CS towards TMC-1 using the QUIJO…
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…
