Handbook for the GREAT08 Challenge: An image analysis competition for cosmological lensing
Sarah Bridle, John Shawe-Taylor, Adam Amara +35
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 g…
PSF calibration requirements for dark energy from cosmic shear
S. Paulin-Henriksson, A. Amara, L. Voigt +2
The control of systematic effects when measuring galaxy shapes is one of the main challenges for cosmic shear analyses. In this context, we study the fundamental limitations on she…
Galaxy cluster mass profiles
L. M. Voigt, A. C. Fabian
Accurate measurements of the mass distribution in galaxy and cluster halos are essential to test the cold dark matter (CDM) paradigm. The cosmological model predicts a universal sh…
Thermal conduction and reduced cooling flows in galaxy clusters
L. M. Voigt, A. C. Fabian
Conduction may play an important role in reducing cooling flows in galaxy clusters. We analyse a sample of sixteen objects using Chandra data and find that a balance between conduc…
