The On-Site Analysis of the Cherenkov Telescope Array
Andrea Bulgarelli, Valentina Fioretti, Andrea Zoli +54
The Cherenkov Telescope Array (CTA) observatory will be one of the largest ground-based very high-energy gamma-ray observatories. The On-Site Analysis will be the first CTA scienti…
CASSIS: The Cornell Atlas of Spitzer/Infrared Spectrograph Sources. II. High-resolution observations
V. Lebouteiller, D. J. Barry, C. Goes +5
The Infrared Spectrograph (IRS) on board the Spitzer Space Telescope observed about 15,000 objects during the cryogenic mission lifetime. Observations provided low-resolution (R~60…
Predicting exoplanet observability in time, contrast, separation and polarization, in scattered light
Guillaume Schworer, Peter G. Tuthill
Polarimetry is one of the keys to enhanced direct imaging of exoplanets. Not only does it deliver a differential observable providing extra contrast, but when coupled with spectros…
Multigroup radiation hydrodynamics with flux-limited diffusion and adaptive mesh refinement
Matthias González, Neil Vaytet, Benoît Commerçon +1
Radiative transfer plays a key role in the star formation process. Due to a high computational cost, radiation-hydrodynamics simulations performed up to now have mainly been carrie…
Observational calibration of the projection factor of Cepheids I. The Type II Cepheid kappa Pavonis
Joanne Breitfelder, Pierre Kervella, Antoine Mérand +5
The distances of pulsating stars, in particular Cepheids, are commonly measured using the parallax of pulsation technique. The different versions of this technique combine measurem…
Performance of the VLT Planet Finder SPHERE II. Data analysis and Results for IFS in laboratory
D. Mesa, R. Gratton, A. Zurlo +33
We present the performance of the Integral Field Spectrograph (IFS) of SPHERE, the high-contrast imager for the ESO VLT telescope designed to perform imaging and spectroscopy of ex…
