Image Analysis for Cosmology: Results from the GREAT10 Star Challenge
T. D. Kitching, B. Rowe, M. Gill +13
We present the results from the first public blind PSF reconstruction challenge, the GRavitational lEnsing Accuracy Testing 2010 (GREAT10) Star Challenge. Reconstruction of a spati…
Is the transition redshift a new cosmological number?
J. A. S. Lima, J. F. Jesus, R. C. Santos +1
Observations from Supernovae Type Ia (SNe Ia) provided strong evidence for an expanding accelerating Universe at intermediate redshifts. This means that the Universe underwent a tr…
Image Analysis for Cosmology: Results from the GREAT10 Galaxy Challenge
T. D. Kitching, S. T. Balan, S. Bridle +25
In this paper we present results from the weak lensing shape measurement GRavitational lEnsing Accuracy Testing 2010 (GREAT10) Galaxy Challenge. This marks an order of magnitude st…
