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 d…
On the abiotic origin of dimethyl sulfide: discovery of DMS in the Interstellar Medium
Miguel Sanz-Novo, Víctor 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…
Discovery of MgS and NaS in the Interstellar Medium and tentative detection of CaO
M. Rey-Montejo, I. Jimenez-Serra, J. Martin-Pintado +12
We report the first detection of the metal-bearing molecules sodium sulfide (NaS) and magnesium sulfide (MgS) and the tentative detection of calcium monoxide (CaO) in the interstel…
First detection in space of the high-energy isomer of cyanomethanimine: H2CNCN
David San Andrés, Víctor M. Rivilla, Laura Colzi +14
We report the first detection in the interstellar medium of -cyanomethanimine (HCNCN), the stable dimer of HCN of highest energy, and the most complex organic molecule ident…
Discovery of thionylimide, HNSO, in space: the first N-, S- and O-bearing interstellar molecule
Miguel Sanz-Novo, Víctor M. Rivilla, Holger S. P. Müller +12
We present the first detection in space of thionylimide (HNSO) toward the Galactic Center molecular cloud G+0.693-0.027, thanks to the superb sensitivity of an ultradeep molecular…
Interstellar detection of O-protonated carbonyl sulfide, HOCS+
Miguel Sanz-Novo, Víctor M. Rivilla, Izaskun Jiménez-Serra +12
We present the first detection in space of O-protonated carbonyl sulfide (\ch{HOCS+}), in the midst of an ultradeep molecular line survey toward the G+0.693-0.027 molecular cloud.…
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…
Amides inventory towards the G+0.693-0.027 molecular cloud
S. Zeng, V. M. Rivilla, I. Jiménez-Serra +6
Interstellar amides have attracted significant attentions as they are potential precursors for a wide variety of organics essential to life. However, our current understanding of t…
A ring-like accretion structure in M87 connecting its black hole and jet
Ru-Sen Lu, Keiichi Asada, Thomas P. Krichbaum +118
The nearby radio galaxy M87 is a prime target for studying black hole accretion and jet formation^{1,2}. Event Horizon Telescope observations of M87 in 2017, at a wavelength of 1.3…
Molecular precursors of the RNA-world in space: new nitriles in the G+0.693-0.027 molecular cloud
Víctor M. Rivilla, Izaskun Jiménez-Serra, Jesus Martín-Pintado +10
Nitriles play a key role as molecular precursors in prebiotic experiments based on the RNA-world scenario for the origin of life. These chemical compounds could have been partially…
Precursors of fatty alcohols in the ISM: Discovery of n-propanol
Izaskun Jimenez-Serra, Lucas F. Rodriguez-Almeida, Jesus Martin-Pintado +12
Theories on the origins of life propose that early cell membranes were synthesized from amphiphilic molecules simpler than phospholipids such as fatty alcohols. The discovery in th…
Unprecedented change in the position of four radio sources
Oleg Titov, Sándor Frey, Sébastien Lambert +7
Astrometric positions of radio-emitting active galactic nuclei (AGNs) can be determined with sub-milliarcsec accuracy using very long baseline interferometry (VLBI). The usually sm…
