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…
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-…
The magnesium paradigm in IRC+10216: Discovery of MgCH, MgCN, MgCH, and MgCN
J. Cernicharo, C. Cabezas, J. R. Pardo +7
We found four series of harmonically related lines in IRC\,+10216 with the Yebes\,40m and IRAM\,30m telescopes. The first series corresponds to a molecule with a rotational constan…
A new protonated molecule discovered in TMC-1: HCCNCH+
M. Agundez, C. Cabezas, N. Marcelino +4
In recent years we have seen an important increase in the number of protonated molecules detected in cold dense clouds. Here we report the detection in TMC-1 of HCCNCH+, the proton…
Discovery of a new molecular ion, HC7NH+, in TMC-1
C. Cabezas, M. Agundez, N. Marcelino +4
We report the detection of the protonated form of HC7N in TMC-1. The discovery of the cation HC7NH+ was carried out via the observation of nine harmonically related lines in the Q-…
Ionise hard: interstellar PO detection
Víctor M. Rivilla, Juan García de la Concepción, Izaskun Jiménez-Serra +13
We report the first detection of the phosphorus monoxide ion (PO) in the interstellar medium. Our unbiased and very sensitive spectral survey towards the G+0.6930.027 mole…
Pure hydrocarbon cycles in TMC-1: Discovery of ethynyl cyclopropenylidene, cyclopentadiene and indene
J. Cernicharo, M. Agundez, C. Cabezas +4
We report the detection for the first time in space of three new pure hydrocarbon cycles in TMC-1: c-C3HCCH (ethynyl cyclopropenylidene), c-C5H6 (cyclopentadiene) and c-C9H8 (inden…
Discovery of the acetyl cation, CH3CO+, in space and in the laboratory
J. Cernicharo, C. Cabezas, S. Bailleux +10
Using the Yebes 40m and IRAM 30m radiotelescopes, we detected two series of harmonically related lines in space that can be fitted to a symmetric rotor. The lines have been seen to…
New molecular species at redshift z=0.89
B. Tercero, J. Cernicharo, S. Cuadrado +2
We present the first detections of CH3SH, C3H+, C3N, HCOOH, CH2CHCN, and H2CN in an extragalactic source. Namely the spiral arm of a galaxy located at z=0.89 on the line of sight t…
Probing the gravitational redshift with an Earth-orbiting satellite
D. A. Litvinov, V. N. Rudenko, A. V. Alakoz +45
We present an approach to testing the gravitational redshift effect using the RadioAstron satellite. The experiment is based on a modification of the Gravity Probe A scheme of nonr…
Planetary Radio Interferometry and Doppler Experiment (PRIDE) technique: A test case of the Mars Express Phobos fly-by
Dmitry A. Duev, Sergei V. Pogrebenko, Giuseppe Cimò +33
The closest ever fly-by of the Martian moon Phobos, performed by the European Space Agency's Mars Express spacecraft, gives a unique opportunity to sharpen and test the Planetary R…
5 year Global 3-mm VLBI survey of Gamma-ray active blazars
J. A. Hodgson, T. P. Krichbaum, A. P. Marscher +7
The Global mm-VLBI Array (GMVA) is a network of 14 3\,mm and 7\,mm capable telescopes spanning Europe and the United States, with planned extensions to Asia. The array is capable o…
Large scale ionization of the Radio Arc region by the Quintuplet and the Arches cluster
N. J. Rodriguez-Fernandez, J. Martin-Pintado, P. de Vicente
(Short version) We present an analysis of selected fine structure lines observed ISO toward the Radio Arc in the Galactic center region (GCR). We study the density of the ionized g…
