Deconvolution with Shapelets (2008)

Melchior, Peter, Andrae, Rene, Maturi, Matteo, Bartelmann, Matthias

We seek to find a shapelet-based scheme for deconvolving galaxy images from the PSF which leads to unbiased shear measurements. Based on the analytic formulation of convolution in shapelet space, we...

Realistic simulations of gravitational lensing by galaxy clusters: extracting arc parameters from mock DUNE images (2007)

Meneghetti, Massimo, Melchior, Peter, Grazian, Andrea, De Lucia, Gabriella, Dolag, Klaus, Bartelmann, Matthias, ...

We present a newly developed code that allows simulations of optical observations of galaxy fields with a variety of instruments. The code incorporates gravitational lensing effects and is targetted...
