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…
Full-sky maps for gravitational lensing of the CMB
Carmelita Carbone, Volker Springel, Carlo Baccigalupi +2
We use the large cosmological Millennium Simulation (MS) to construct the first all-sky maps of the lensing potential and the deflection angle, aiming at gravitational lensing of t…
Model-independent determination of the cosmic expansion rate. I. Application to type-Ia supernovae
Claudia Mignone, Matthias Bartelmann
Aims: In view of the substantial uncertainties regarding the possible dynamics of the dark energy, we aim at constraining the expansion rate of the universe without reference to a…
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…
Asymmetric Gravitational Lenses in TeVeS and Application to the Bullet Cluster
M. Feix, C. Fedeli, M. Bartelmann
Aims: We explore the lensing properties of asymmetric matter density distributions in Bekenstein's Tensor-Vector-Scalar theory (TeVeS). Methods: Using an iterative Fourier-based so…
Probing the dynamical state of galaxy clusters
Ewald Puchwein, Matthias Bartelmann
We show how hydrostatic equilibrium in galaxy clusters can be quantitatively probed combining X-ray, SZ, and gravitational-lensing data. Our previously published method for recover…
