Extending the supernova Hubble diagram to z~1.5 with the Euclid space mission
P. Astier, C. Balland, M. Brescia +25
We forecast dark energy constraints that could be obtained from a new large sample of Type Ia supernovae where those at high redshift are acquired with the Euclid space mission. We…
A framework for modeling the detailed optical response of thick, multiple segment, large format sensors for precision astronomy applications
Andrew Rasmussen, Pierre Antilogus, Pierre Astier +11
Near-future astronomical survey experiments, such as LSST, possess system requirements of unprecedented fidelity that span photometry, astrometry and shape transfer. Some of these…
First experimental constraints on the disformally coupled Galileon model
J. Neveu, V. Ruhlmann-Kleider, P. Astier +6
The Galileon model is a modified gravity model that can explain the late-time accelerated expansion of the Universe. In a previous work, we derived experimental constraints on the…
The brighter-fatter effect and pixel correlations in CCD sensors
P. Antilogus, P. Astier, P. Doherty +2
We present evidence that spots imaged using astronomical CCDs do not exactly scale with flux: bright spots tend to be broader than faint ones, using the same illumination pattern.…
Cosmological Parameter Uncertainties from SALT-II Type Ia Supernova Light Curve Models
J. Mosher, J. Guy, R. Kessler +11
We use simulated SN Ia samples, including both photometry and spectra, to perform the first direct validation of cosmology analysis using the SALT-II light curve model. This valida…
Improved cosmological constraints from a joint analysis of the SDSS-II and SNLS supernova samples
M. Betoule, R. Kessler, J. Guy +60
We present cosmological constraints from a joint analysis of type Ia supernova (SN Ia) observations obtained by the SDSS-II and SNLS collaborations. The data set includes several l…
