Reliable Shapelet Image Analysis
P. Melchior, M. Meneghetti, M. Bartelmann
Aims: We discuss the applicability and reliability of the shapelet technique for scientific image analysis. Methods: We quantify the effects of non-orthogonality of sampled shapele…
Searching dark-matter halos in the GaBoDS survey
M. Maturi, M. Schirmer, M. Meneghetti +2
We apply the linear filter for the weak-lensing signal of dark-matter halos developed in Maturi et al. (2005) to the cosmic-shear data extracted from the Garching-Bonn-Deep-Survey…
Early structure formation in quintessence models and its implications for cosmic reionisation from first stars
U. Maio, K. Dolag, M. Meneghetti +5
We present the first hydrodynamic N-body simulations of primordial gas clouds responsible for the reionisation process in dark energy cosmologies. We compare the cosmological const…
Arc sensitivity to cluster ellipticity, asymmetries and substructures
Massimo Meneghetti, Rodolfo Argazzi, Francesco Pace +5
We investigate how ellipticity, asymmetries and substructures separately affect the ability of galaxy clusters to produce strong lensing events, i.e. gravitational arcs, and how th…
