Formation of adducts of CH with Na, Mg and Al metal cations by radiative association
Niyazi Bulut, Octavio Roncero, Maria Mallo +6
The Mg-bearing cations MgCH, MgCH, MgCN, and MgCN have been recently observed in the carbon-rich envelope IRC\,+10216. These species are thought to…
Thioacetaldehyde (CH3CHS) on interstellar ices: a key molecule to unravel two chemical dichotomies in the ISM
María Mallo, Miguel Sanz-Novo, Marcelino Agúndez +6
Thioacetaldehyde (CH3CHS), recently detected in TMC-1, has an abundance approximately 36 times lower than its oxygen analog, acetaldehyde (CH3CHO). This makes the CH3CHS/CH3CHO pai…
Laboratory spectroscopy, theoretical characterization, and astronomical search for syn-propenethial (CH2CHCHS)
Germán Molpeceres, Carlos Cabezas, Marcelino Agúndez +5
We report the laboratory characterization of the higher-energy isomer of propenethial, syn-CH2CHCHS. While the lower-energy isomer, anti-CH2CHCHS, was detected in the interstellar…
Ion-molecule routes towards cycles in TMC-1. An automated study of the C2H4 + CH2CCH+ reaction
María Mallo, Marcelino Agúndez, Carlos Cabezas +3
Cyclopentadiene (c-C5H6) is considered a key molecule in the formation of polycyclic aromatic hydrocarbons (PAHs) in the interstellar medium (ISM). The synthesis of PAHs from simpl…
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 d…
Discovery of HCCCH2CCH in TMC-1 with the QUIJOTE line survey
R. Fuentetaja, M. Agúndez, C. Cabezas +5
We present the first detection in space of 1,4-pentadiyne. It has been found towards TMC-1 with the QUIJOTE line survey in the 31-50 GHz range. We observed a total of 17 transition…
Study of the HCCNC and HNCCC isotopologs in TMC-1
José Cernicharo, Belén Tercero, Carlos Cabezas +5
We present the detection of the three 13C isotopologs of HCCNC and HNCCC toward TMC-1 using the QUIJOTE line survey. In addition, the D species has also been detected for these two…
Discovery of thiofulminic acid with the QUIJOTE line survey: A study of the isomers of HNCS and HNCO in TMC-1
José Cernicharo, Marcelino Agúndez, Carlos Cabezas +4
We present the first detection of HCNS (thiofulminic acid) in space with the QUIJOTE line survey in the direction of TMC-1. We performed a complete study of the isomers of CHNS and…
Cumulene carbenes in TMC-1: Astronomical discovery of -HC
C. Cabezas, B. Tercero, M. Agúndez +4
We report the first detection in space of the cumulene carbon chain -HC. A total of eleven rotational transitions, with = 7-10 and = 0 and 1, were detecte…
Space and laboratory observation of the deuterated cyanomethyl radical HDCCN
Carlos Cabezas, Yasuki Endo, Evelyne Roueff +4
Our observations of TMC-1 with the Yebes 40 m radio telescope in the 31.0-50.3 GHz range allowed us to detect a group of unidentified lines, showing a complex line pattern indicati…
Tentative detection of HC5NH+ in TMC-1
N. Marcelino, M. Agundez, B. Tercero +5
Using the Yebes 40m radio telescope, we report the detection of a series of seven lines harmonically related with a rotational constant B0=1295.81581 +/- 0.00026 MHz and a distorti…
Discovery of HC3O+ in space: The chemistry of O-bearing species in TMC-1
J. Cernicharo, N. Marcelino, M. Agundez +5
Using the Yebes 40m and IRAM 30m radio telescopes, we detected a series of harmonically related lines with a rotational constant B0=4460.590 +/- 0.001 MHz and a distortion constant…
Discovery of HC4NC in TMC-1: A study of the isomers of HC3N, HC5N, and HC7N
