“…Furthermore, KIDs are fast detectors, with typical time constants of about 100 µs (Catalano et al 2016;Monfardini et al 2016), and they can be used at very high sampling rates up to few megaherz (Swenson et al 2010;Bourrion et al 2016;Fasano et al 2020). This makes KIDs a promising tool for investigating pulsars in unexplored sections of their spectrum and test models of pulsar magnetospheres.…”

Context. The investigation of pulsars between millimetre and optical wavelengths is challenging due to the faintness of the pulsar signals and the relative low sensitivity of the available facilities compared to 100 m class telescopes operating in the centimetre band. The kinetic inductance detector (KID) technology offers large instantaneous bandwidths and a high sensitivity that can help to increase the ability of existing observatories at short wavelengths substantially to detect pulsars and transient emission. Aims. To investigate whether pulsars can be detected with KIDs, we observed the anomalous X-ray pulsar XTE J1810−197 with the New IRAM KIDs Array-2 (NIKA2) camera installed at the IRAM 30 m telescope in Spain. Methods. Several short observations of XTE J1810−197 were made on 2019 March 25 under good weather conditions to verify the stability of the KIDs and to try to detect the expected broadband pulsations from the neutron star. Results. We detected the pulsations from the pulsar with NIKA2 at its two operating frequency bands, 150 and 260 GHz (λ = 2.0 and 1.15 mm, respectively). This is the first time that a pulsar is detected with a receiver based on KID technology in the millimetre band. In addition, this is the first report of short millimetre emission from XTE J1810−197 after its reactivation in December 2018, and it is the first time that the source is detected at 260 GHz, which gives us new insights into the radio emission process of the star. Conclusions. We demonstrate that KIDs can fulfil the technical requirements for detecting pulsed emission from neutron stars in the millimetre band. We show that the magnetar XTE J1810−197 is again emitting strong pulsations in the short millimetre band.

“…The δ f is much smaller than the resonance width, and it is of the order of a few kHz. The calibration step is performed at the beginning of each interferogram, while the direction of motion of the MpI rooftop mirror is changing (Fasano et al 2020a). In our opinion, this approach represents the best trade-off between optimal calibration and observing efficiency, that is, the fraction of time that is devoted to the science data stream.…”

“…The instrument, named CONCERTO (for CarbON CII line in post-rEionisation and ReionisaTiOn epoch), has been designed to interface with the Atacama Pathfinder EXperiment (APEX) 12-m telescope (Güsten et al 2006). A pathfinder instrument, named KISS that is based on the same concept, has been built by our collaboration and deployed in November 2018, at the Teide Observatory (Fasano et al 2020a).…”

Context. Characterising the large-scale structure in the Universe from present times to the high redshift epoch of reionisation is essential to constraining the cosmology, the history of star formation, and reionisation, to measuring the gas content of the Universe, and to obtaining a better understanding of the physical processes that drive galaxy formation and evolution. Using the integrated emission from unresolved galaxies or gas clouds, line intensity mapping (LIM) provides a new observational window to measure the larger properties of structures. This very promising technique motivates the community to plan for LIM experiments. Aims. We describe the development of a large field-of-view instrument, named CONCERTO (for CarbON CII line in post-rEionisation and ReionisaTiOn epoch), operating in the range 130–310 GHz from the APEX 12-m telescope (5100 m above sea level). CONCERTO is a low-resolution spectrometer based on the lumped element kinetic inductance detectors (LEKID) technology. Spectra are obtained using a fast Fourier transform spectrometer (FTS), coupled to a dilution cryostat with a base temperature of 0.1 K. Two two kilo-pixel arrays of LEKID are mounted inside the cryostat that also contains the cold optics and the front-end electronics. Methods. We present, in detail, the technological choices leading to the instrumental concept, together with the design and fabrication of the instrument and preliminary laboratory tests on the detectors. We also give our best estimates for CONCERTO sensitivity and give predictions for two of the main scientific goals of CONCERTO, that is, a [CII]-intensity mapping survey and observations of galaxy clusters. Results. We provide a detailed description of the instrument design. Based on realistic comparisons with existing instruments developed by our group (NIKA, NIKA2, and KISS), and on the laboratory characterisation of our detectors, we provide an estimate for CONCERTO sensitivity on the sky. Finally, we describe, in detail, two of the main scientific goals offered by CONCERTO at APEX.

“…The spectral resolution demanded for such a scientific target is of few GHz with a total bandwidth from 10 up to 100 GHz (see [11] for details), but an high mapping speed is required to cover the typical low-redshift cluster of galaxies size (few degrees). This is the main reason for adopting a wide Field of View (FoV) Martin Puplett Interferometer (MPI) (see [12] for a detailed description of the MPI and [13] for the KISS configuration) with large-array detectors with respect to the heterodyne at high spectral resolution (such as ALMA [14] and NOEMA [15]) covering a smaller instantaneous FoV.…”

Clusters of galaxies are used to map the large-scale structures in the universe and as probe of universe evolution. They can be observed through the Sunyaev-Zel'dovich (SZ) effect. In this respect the spectro-imaging at low resolution frequency is an important tool, today, for the study of cluster of galaxies. We have developed KISS (KIDs Interferometer Spectrum Survey), a spectrometric imager dedicated to the secondary anisotropies of the Cosmic Microwave Background (CMB). The multi-frequency approach permits to improve the component separation with respect to predecessor experiments. In this paper, firstly, we provide a description of the scientific context and the state of the art of SZ observations. Secondly, we describe the KISS instrument. Finally, we show preliminary results of the ongoing commissioning campaign. Scientific contextThe SZ effect is a spectral distortion of the CMB due to the interaction between CMB photons and the hot electrons in cluster of galaxies (see [1] for a detailed description). This effect is exploited for several purpose in contemporary cosmology: the detection of clusters of galaxies, their morphological mapping and the evaluation of the cosmological parameters from the ΛCDM model [2].The overall SZ effect includes two components: the thermal SZ (tSZ) due to the Inverse Compton scattering with the Intra Cluster Medium (ICM) in clusters and the kinematic SZ (kSZ) induced by its celestial structure bulk motion.The tSZ effect is particularly interesting as its spectral signature provides a unique possibility to detect and study clusters of galaxies at any redshift, because it does not have *
