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…
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…
First detection of HS2 in a cold dark cloud
G. Esplugues, M. Agúndez, G. Molpeceres +5
We report the first detection of HS2 towards the cold dark cloud TMC-1. This is the first observation of a chemical species containing more than one sulphur atom in this type of so…
A search for the three isomers of cyano-1,3-butadiene in TMC-1: Implications for bottom-up routes involving 1,3-butadiene
M. Agundez, C. Cabezas, N. Marcelino +4
The molecule 1,3-butadiene (CH2CHCHCH2) could play a key role in the synthesis of the cyclic molecules cyclopentadiene and benzene in cold dense clouds. Since 1,3-butadiene is non-…
Detection of thioacetaldehyde (CH3CHS) in TMC-1: sulfur-oxygen differentiation along the hydrogenation sequence
M. Agundez, G. Molpeceres, C. Cabezas +5
In recent years the chemistry of sulfur in the interstellar medium has experienced a renewed interest due to the detection of a large variety of molecules containing sulfur. Here w…
