StarDICE I: sensor calibration bench and absolute photometric calibration of a Sony IMX411 sensor
Marc Betoule, Sarah Antier, Emmanuel Bertin +18
The Hubble diagram of type-Ia supernovae (SNe-Ia) provides cosmological constraints on the nature of dark energy with an accuracy limited by the flux calibration of currently avail…
Gravitation And the Universe from large Scale-Structures: The GAUSS mission concept
Alain Blanchard, Aubourg Éric, Philippe Brax +25
Today, thanks in particular to the results of the ESA Planck mission, the concordance cosmological model appears to be the most robust to describe the evolution and content of the…
Fink, a new generation of broker for the LSST community
Anais Möller, Julien Peloton, Emille E. O. Ishida +33
Fink is a broker designed to enable science with large time-domain alert streams such as the one from the upcoming Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST).…
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…
Observational status of the Galileon model general solution from cosmological data and gravitational waves
Clément Leloup, Vanina Ruhlmann-Kleider, Jeremy Neveu +1
The Galileon model is a tensor-scalar theory of gravity which explains the late acceleration of the Universe expansion with no instabilities and recovers General Relativity in the…
On the statistics of the polarized submillimetre emission maps from thermal dust in the turbulent, magnetized, diffuse ISM
F. Levrier, J. Neveu, E. Falgarone +4
[abridged] The interstellar medium is now widely recognized to display features ascribable to magnetized turbulence. With the public release of Planck data and the current balloon-…
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…
Dependence of Type Ia supernova luminosities on their local environment
Matthieu Roman, Delphine Hardin, Marc Betoule +18
We present a fully consistent catalog of local and global properties of host galaxies of 882 Type Ia supernovæ (SNIa) that were selected based on their light-curve properties, span…
A direct method to compute the galaxy count angular correlation function including redshift-space distortions
J. -E. Campagne, S. Plaszczynski, J. Neveu
In the near future, cosmology will enter the wide and deep galaxy survey area allowing high-precision studies of the large scale structure of the universe in three dimensions. To t…
Angpow: a software for the fast computation of accurate tomographic power spectra
J. -E. Campagne, J. Neveu, S. Plaszczynski
The statistical distribution of galaxies is a powerful probe to constrain cosmological models and gravity. In particular the matter power spectrum brings information about t…
Photometric classification of type Ia supernovae in the SuperNova Legacy Survey with supervised learning
A. Möller, V. Ruhlmann-Kleider, C. Leloup +6
In the era of large astronomical surveys, photometric classification of supernovae (SNe) has become an important research field due to limited spectroscopic resources for candidate…
Constraining the CDM and Galileon models with recent cosmological data
J. Neveu, V. Ruhlmann-Kleider, P. Astier +4
The Galileon theory belongs to the class of modified gravity models that can explain the late-time accelerated expansion of the Universe. In previous works, cosmological constraint…
SNIa detection in the SNLS photometric analysis using Morphological Component Analysis
A. Möller, V. Ruhlmann-Kleider, F. Lanusse +3
Detection of supernovae and, more generally, of transient events in large surveys can provide numerous false detections.In the case of a deferred processing of survey images, this…
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…
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…
Experimental constraints on the uncoupled Galileon model from SNLS3 data and other cosmological probes
J. Neveu, V. Ruhlmann-Kleider, A. Conley +4
The Galileon model is a modified gravity theory that may provide an explanation for the accelerated expansion of the Universe. This model does not suffer from instabilities or ghos…
