The NIKA instrument: results and perspectives towards a permanent KID based camera for the Pico Veleta observatory
A. D'Addabbo, R. Adam, A. Adane +32
The New IRAM KIDs Array (NIKA) is a pathfinder instrument devoted to millimetric astronomy. In 2009 it was the first multiplexed KID camera on the sky; currently it is installed at…
Design of light concentrators for Cherenkov telescope observatories
F. Hénault, P. O. Petrucci, L. jocou +7
The Cherenkov Telescope Array (CTA) will be the largest cosmic gamma ray detector ever built in the world. It will be installed at two different sites in the North and South hemisp…
FIRST, a fibered aperture masking instrument II. Spectroscopy of the Capella binary system at the diffraction limit
E. Huby, G. Duchêne, F. Marchis +7
FIRST is a prototype instrument built to demonstrate the capabilities of the pupil remapping technique, using single-mode fibers and working at visible wavelengths. We report on ob…
Perspectives for the study of gas in protoplanetary disks and accretion/ejection phenomena in young stars with the near-IR spectrograph SPIROU at the CFHT
A. Carmona, J. Bouvier, X. Delfosse
Near-IR atomic and molecular transitions are powerful tools to trace the warm and hot gas in the circumstellar environment of young stars. Ro-vibrational transitions of H2 and H2O,…
Latest NIKA results and the NIKA-2 project
A. Monfardini, R. Adam, A. Adane +32
NIKA (New IRAM KID Arrays) is a dual-band imaging instrument installed at the IRAM (Institut de RadioAstronomie Millimetrique) 30-meter telescope at Pico Veleta (Spain). Two distin…
Simulating gamma-ray binaries with a relativistic extension of RAMSES
Astrid Lamberts, Sebastien Fromang, Guillaume Dubus +1
Gamma-ray binaries are composed of a massive star and a rotation-powered pulsar with a highly relativistic wind. The collision between the winds from both objects creates a shock s…
First experimental results of very high accuracy centroiding measurements for the neat astrometric mission
A. Crouzier, F. Malbet, O. Preis +19
NEAT is an astrometric mission proposed to ESA with the objectives of detecting Earth-like exoplanets in the habitable zone of nearby solar-type stars. NEAT requires the capability…
Flight demonstration of formation flying capabilities for future missions (NEAT Pathfinder)
M. Delpech, F. Malbet, T. Karlsson +3
PRISMA is a demonstration mission for formation-flying and on-orbit-servicing critical technologies that involves two spacecraft launched in low Earth orbit in June 2010 and still…
Performances tests on the SPHERE-IFS
Dino Mesa, Raffaele Gratton, Riccardo U. Claudi +13
Until now, just a few extrasolar planets (~30 out of 860) have been found through the direct imaging method. This number should greatly improve when the next generation of High Con…
The NectarCAM camera project
J-F. Glicenstein, M. Barcelo, J-A. Barrio +57
In the framework of the next generation of Cherenkov telescopes, the Cherenkov Telescope Array (CTA), NectarCAM is a camera designed for the medium size telescopes covering the cen…
IRDIS, the dual-band imager camera of SPHERE: testing the performances in laboratory
A. Zurlo, A. Vigan, C. Moutou +12
Next year the second generation instrument SPHERE will begin science operations at the Very Large Telecope (ESO). This instrument will be dedicated to the search for exoplanets thr…
Dynamical Analysis of Nearby ClustErs. Automated astrometry from the ground: precision proper motions over wide field
H. Bouy, E. Bertin, E. Moraux +5
The kinematic properties of the different classes of objects in a given association hold important clues about its member's history, and offer a unique opportunity to test the pred…
Building galaxies, stars, planets and the ingredients for life between the stars. A scientific proposal for a European Ultraviolet-Visible Observatory (EUVO)
Ana I. Gómez de Castro, Thierry Appourchaux, Martin Barstow +36
The growth of luminous structures and the building blocks of life in the Universe began as primordial gas was processed in stars and mixed at galactic scales. The mechanisms respon…
Planck 2013 results. IX. HFI spectral response
Planck Collaboration, P. A. R. Ade, N. Aghanim +217
The Planck High Frequency Instrument (HFI) spectral response was determined through a series of ground based tests conducted with the HFI focal plane in a cryogenic environment pri…
Planck 2013 results. VII. HFI time response and beams
Planck Collaboration, P. A. R. Ade, N. Aghanim +220
This paper characterizes the effective beams,the effective beam window functions and the associated errors for the Planck HFI detectors. The effective beam is the angular response…
Planck 2013 results. V. LFI calibration
Planck Collaboration, N. Aghanim, C. Armitage-Caplan +217
We discuss the methods employed to photometrically calibrate the data acquired by the Low Frequency Instrument on Planck. Our calibration is based on a combination of the Orbital D…
Planck 2013 results. II. Low Frequency Instrument data processing
Planck Collaboration, N. Aghanim, C. Armitage-Caplan +229
We describe the data processing pipeline of the Planck Low Frequency Instrument (LFI) data processing centre (DPC) to create and characterize full-sky maps based on the first 15.5…
Three-Dimensional Dust Radiative Transfer
