Forecasts of non-Gaussian parameter spaces using Box-Cox transformations

, 2011
Forecasts of statistical constraints on model parameters using the Fisher matrix abound in many fields of astrophysics. The Fisher matrix formalism involves the assumption of Gaussianity in parameter space and hence fails to predict complex features of ...

Non-parametric inversion of gravitational lensing systems with few images using a multi-objective genetic algorithm

, 2007
Galaxies acting as gravitational lenses are surrounded by, at most, a handful of images. This apparent paucity of information forces one to make the best possible use of what information is available to invert the lens system.

The Orbital Structure of Dark Matter Halos with Gas

, 2000
With the success of the Chandra and XMM missions and the maturation of gravitational lensing techniques, powerful constraints on the orbital structure of cluster dark matter halos are possible.
