Weak lensing forecasts for dark energy, neutrinos and initial conditions (2009)
Debono, Ivan, Rassat, Anais, Refregier, Alexandre, Amara, Adam, Kitching, Thomas
Weak gravitational lensing provides a sensitive probe of cosmological parameters by measuring the mass distribution and the geometry of the low redshift universe. We show how an all-sky weak lensing...
Results of the GREAT08 Challenge: An image analysis competition for cosmological lensing (2009)
Bridle, Sarah, Balan, Sreekumar T., Bethge, Matthias, Gentile, Marc, Harmeling, Stefan, Heymans, Catherine, ...
We present the results of the GREAT08 Challenge, a blind analysis challenge to infer weak gravitational lensing shear distortions from images. The primary goal was to stimulate new ideas by...
Cloud Cosmology : Building the Web Interface for iCosmo (2009)
Kitching, Thomas, Amara, Adam, Rassat, Anais, Refregier, Alexandre
Astronomy and cosmology have embraced the internet. We routinely and successfully use the internet as a repository for sharing code, publications and information, and as a computational resource....
iCosmo: an Interactive Cosmology Package (2008)
Refregier, Alexandre, Amara, Adam, Kitching, Thomas, Rassat, Anais
iCosmo is a software package to perform interactive cosmological calculations for the low redshift universe. The computation of distance measures, the matter power spectrum, and the growth factor is...
Deconstructing Baryon Acoustic Oscillations: A Comparison of Methods (2008)
Rassat, Anais, Amara, Adam, Amendola, Luca, Castander, Francisco J., Kitching, Thomas, Kunz, Martin, ...
The Baryon Acoustic Oscillations (BAOs) or baryon wiggles which are present in the galaxy power spectrum at scales 100-150Mpc/h are powerful features with which to constrain cosmology. The potential...
Handbook for the GREAT08 Challenge: An image analysis competition for cosmological lensing (2008)
Bridle, Sarah, Shawe-Taylor, John, Amara, Adam, Applegate, Douglas, Balan, Sreekumar T., Berge, Joel, ...
The GRavitational lEnsing Accuracy Testing 2008 (GREAT08) Challenge focuses on a problem that is of crucial importance for future observations in cosmology. The shapes of distant galaxies can be used...
