Combining weak and strong cluster lensing: Applications to simulations and MS 2137
J. Merten, M. Cacciato, M. Meneghetti +2
AIMS. While weak lensing cannot resolve cluster cores and strong lensing is almost insensitive to density profiles outside the scale radius, combinations of both effects promise to…
Strong lensing statistics and the power spectrum normalisation
C. Fedeli, M. Bartelmann, M. Meneghetti +1
We use semi-analytic modelling of the galaxy-cluster population and its strong lensing efficiency to explore how the expected abundance of large gravitational arcs on the sky depen…
Statistical properties of SZ and X-ray cluster detections
F. Pace, M. Maturi, M. Bartelmann +4
Aims. We calibrate the number density, completeness, reliability and the lower mass limit of galaxy-cluster detections through their thermal SZ signal, and compare them to X-ray cl…
Realistic simulations of gravitational lensing by galaxy clusters: extracting arc parameters from mock DUNE images
Massimo Meneghetti, Peter Melchior, Andrea Grazian +6
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 effect…
Cosmic reionization in a dynamic quintessence cosmology
D. Crociani, M. Viel, L. Moscardini +2
In this paper we investigate the effects that a dynamic dark energy component dominant in the universe at late epochs has on reionization. We follow the evolution of HII regions wi…
Effects of the halo concentration distribution on strong-lensing optical depth and X-ray emission
C. Fedeli, M. Bartelmann, M. Meneghetti +1
We use simulated merger trees of galaxy-cluster halos to study the effect of the halo concentration distribution on strong lensing and X-ray emission. Its log-normal shape typicall…
