ISPY -- NaCo Imaging Survey for Planets around Young stars. CenteR: the impact of centering and frame selection
N. Godoy, J. Olofsson, A. Bayo +18
Abridged: Direct imaging has made significant progress over the past decade leading to the detection of several giant planets. Observing strategies and data rates vary from instrum…
Probing the role of magnetic fields in star-forming filaments: NIKA2-Pol commissioning results toward OMC-1
H. Ajeddig, R. Adam, P. Ade +43
Dust polarization observations are a powerful, practical tool to probe the geometry (and to some extent, the strength) of magnetic fields in star-forming regions. In particular, Pl…
Faint objects in motion: the new frontier of high precision astrometry
Fabien Malbet, Céline Boehm, Alberto Krone-Martins +83
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
Observations with KIDs Interferometer Spectrum Survey(KISS)
A. Fasano, A. Catalano, J. F. Macías-Pérez +33
We describe the preliminary on-sky results of the KIDs Interferometer Spectrum Survey (KISS), a spectral imager with a 1 deg field of view (FoV). The instrument operates in the ran…
CONCERTO at APEX: Installation and first phase of on-sky commissioning
A. Catalano, P. Ade, M. Aravena +40
CONCERTO (CarbON CII line in post-rEionisation and ReionisaTiOn) is a large field-of-view (FoV) spectro-imager that has been installed on the Cassegrain Cabin of Atacama Pathfinder…
Measurement of performance of the NectarCAM photodetectors
A. Tsiahina, P. Jean, J. -F. Olive +26
NectarCAM is a camera for the medium-sized telescopes of the Cherenkov Telescope Array (CTA), which covers the energy range of 100 GeV to 30 TeV. The camera is equipped with 265 fo…
Accurate sky signal reconstruction for ground-based spectroscopy with kinetic inductance detectors
A. Fasano., J. F. Macías-Pérez, A. Benoit +33
Context. Wide-field spectrometers are needed to deal with current astrophysical challenges that require multiband observations at millimeter wavelengths. An example of these is the…
Compensation of differential dispersion: application to multiband stellar interferometry
Cyril Pannetier, Denis Mourard, Frédéric Cassaing +5
With the aim of pushing the limiting magnitude of interferometric instruments, the need for wide-band detection channels and for a coordinated operation of different instruments ha…
CONCERTO at APEX: installation and technical commissioning
A. Monfardini, A. Beelen, A. Benoit +41
We describe the deployment and first tests on Sky of CONCERTO, a large field-of-view (18.6arc-min) spectral-imaging instrument. The instrument operates in the range 130-310GHz from…
Spectral unmixing for exoplanet direct detection in hyperspectral data
Julien Rameau, Jocelyn Chanussot, Alexis Carlotti +2
The direct detection of exoplanets with high-contrast instruments can be boosted with high spectral resolution. For integral field spectrographs yielding hyperspectral data, this m…
Radiation-Hydrodynamics with MPI-AMRVAC: Flux-Limited Diffusion
N. Moens, J. O. Sundqvist, I. El Mellah +3
Radiation controls the dynamics and energetics of many astrophysical environments. To capture the coupling between the radiation and matter, however, is often a physically complex…
High-precision astrometric studies in direct imaging with SPHERE
A. -L. Maire, G. Chauvin, A. Vigan +15
Orbital monitoring of exoplanetary and stellar systems is fundamental for analysing their architecture, dynamical stability and evolution, and mechanisms of formation. Current high…
PCS -- A Roadmap for Exoearth Imaging with the ELT
Markus Kasper, Nelly Cerpa Urra, Prashant Pathak +22
The Planetary Camera and Spectrograph (PCS) for the Extremely Large Telescope (ELT) will be dedicated to detecting and characterising nearby exoplanets with sizes from sub-Neptune…
Miec: A Bayesian hierarchical model for the analysis of nearby young open clusters
J. Olivares, H. Bouy, L. M. Sarro +4
Context. The analysis of luminosity and mass distributions of young stellar clusters is essential to understanding the star-formation process. However, the gas and dust left over b…
Laboratory characterization of FIRSTv2 photonic chip for the study of substellar companions
K. Barjot, E. Huby, S. Vievard +14
FIRST (Fibered Imager foR a Single Telescope instrument) is a post-AO instrument that enables high contrast imaging and spectroscopy at spatial scales below the diffraction limit.…
The SPIRou wavelength calibration for precise radial velocities in the near infrared
M. J. Hobson, F. Bouchy, N. J. Cook +8
SPIRou is a near-infrared (nIR) spectropolarimeter at the CFHT, covering the YJHK nIR spectral bands (). We describe the development and current status of th…
