Development of an unbiased cosmic shear estimator measured on galaxy images
Enya Van den Abeele, Pierre Astier, Anna Niemiec
Since cosmic shear was first observed in 2000, it has become a key cosmological probe and promises to deliver exquisite dark energy constraints. However, shear is inferred from coh…
PlatoSim: An end-to-end PLATO camera simulator for modelling high-precision space-based photometry
N. Jannsen, J. De Ridder, D. Seynaeve +21
PLAnetary Transits and Oscillations of stars (PLATO) is the ESA M3 space mission dedicated to detect and characterise transiting exoplanets including information from the asterosei…
Improving the astrometric solution of the Hyper Suprime-Cam with anisotropic Gaussian processes
P. -F. Léget, P. Astier, N. Regnault +5
We study astrometric residuals from a simultaneous fit of Hyper Suprime-Cam images. We aim to characterize these residuals and study the extent to which they are dominated by atmos…
Peculiar velocity cosmology with type Ia supernovae
R. Graziani, M. Rigault, N. Regnault +20
Type Ia Supernovae have yet again the opportunity to revolutionize the field of cosmology as the new generation of surveys are acquiring thousands of nearby SNeIa opening a new era…
The shape of the Photon Transfer Curve of CCD sensors
Pierre Astier, Pierre Antilogus, Claire Juramy +4
The Photon Transfer Curve (PTC) of a CCD depicts the variance of uniform images as a function of their average. It is now well established that the variance is not proportional to…
The ESO's VLT Type Ia supernova spectral set of the final two years of SNLS
C. Balland, F. Cellier-Holzem, C. Lidman +24
We aim to present 70 spectra of 68 new high-redshift type Ia supernovae (SNeIa) measured at ESO's VLT during the final two years of operation (2006-2008) of the Supernova Legacy Su…
