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…
Chemical study of two starless cores in the B213/L1495 filament
L. Moral-Almansa, A. Fuente, M. RodrÃguez-Baras +7
The chemical evolution of pre-stellar cores during their transition to a protostellar stage is not yet fully understood. Detailed chemical characterizations of these sources are ne…
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…
Discovery of linear propadienone: Study of the chemistry of linear and cyclic HCO and HCS in TMC-1
G. Esplugues, J. C. Loison, M. Agúndez +4
We report the first detection in space of propadienone, the linear isomer (l-HCO) of cyclopropenone (c-HCO). We also report the first detection of the isotopologue…
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…
