The Canfranc Axion Detection Experiment (CADEx): Search for axions at 90 GHz with Kinetic Inductance Detectors
Beatriz Aja, Sergio Arguedas Cuendis, Ivan Arregui +33
We propose a novel experiment, the Canfranc Axion Detection Experiment (CADEx), to probe dark matter axions with masses in the range 330-460 eV, within the W-band (80-110 GHz),…
Ultra-deep 31.0-50.3 GHz spectral survey of IRC+10216
J. R. Pardo, J. Cernicharo, B. Tercero +8
Context. IRC+10216, the carbon-rich envelope of the asymptotic giant branch (AGB) star CW Leo, is one of the richest molecular sources in the sky. Available spectral surveys below…
Wide-band full-wave electromagnetic modal analysis of the coupling between dark-matter axions and photons in microwave resonators
P. Navarro, Benito Gimeno, A. Alvarez Melcon +9
The electromagnetic coupling axion-photon in a microwave cavity is revisited with the Boundary Integral - Resonant Mode Expansion (BI-RME) 3D technique. Such full-wave modal techni…
First results of the CAST-RADES haloscope search for axions at 34.67 eV
A. Álvarez Melcón, S. Arguedas Cuendis, J. Baier +56
We present results of the Relic Axion Dark-Matter Exploratory Setup (RADES), a detector which is part of the CERN Axion Solar Telescope (CAST), searching for axion dark matter in t…
TMC-1, the starless core sulfur factory: Discovery of NCS, HCCS, H2CCS, H2CCCS, and C4S and detection of C5S
J. Cernicharo, C. Cabezas, M. Agundez +7
We report the detection of the sulfur-bearing species NCS, HCCS, H2CCS, H2CCCS, and C4S for the first time in space. These molecules were found towards TMC-1 through the observatio…
Discovery of the propargyl radical (CH2CCH) in TMC-1: one of the most abundant radicals ever found and a key species for cyclization to benzene in cold dark clouds
M. Agundez, C. Cabezas, B. Tercero +4
We present the first identification in interstellar space of the propargyl radical (CH2CCH). This species was observed in the cold dark cloud TMC-1 using the Yebes 40m telescope. T…
Discovery of allenyl acetylene, H2CCCHCCH, in TMC-1. A study of the isomers of C5H4
J. Cernicharo, C. Cabezas, M. Agundez +7
We present the discovery in TMC-1 of allenyl acetylene, H2CCCHCCH, through the observation of nineteen lines with a signal-to-noise ratio ~4-15. For this species, we derived a rota…
Discovery of CH2CHCCH and detection of HCCN, HC4N, CH3CH2CN, and, tentatively, CH3CH2CCH in TMC-1
J. Cernicharo, M. Agundez, C. Cabezas +7
We present the discovery in TMC-1 of vinyl acetylene, CH2CHCCH, and the detection, for the first time in a cold dark cloud, of HCCN, HC4N, and CH3CH2CN. A tentative detection of CH…
Space and laboratory discovery of HC3S+
J. Cernicharo, C. Cabezas, Y. Endo +5
We report the detection in TMC-1 of the protonated form of C3S. The discovery of the cation HC3S+ was carried through the observation of four harmonically related lines in the Q ba…
Yebes 40 m radio telescope and the broad band NANOCOSMOS receivers at 7 mm and 3 mm for line surveys
