Weak gravitational lensing
Matthias Bartelmann, Matteo Maturi
According to the theory of general relativity, masses deflect light in a way similar to convex glass lenses. This gravitational lensing effect is astigmatic, giving rise to image d…
Comparisons between isothermal and NFW mass profiles for strong-lensing galaxy clusters
Chenggang Shu, Binglu Zhou, Matthias Bartelmann +3
While both isothermal and NFW-based mass models for galaxy clusters are widely adopted in strong-lensing studies, they cannot easily be distinguished based solely on observed posit…
Improving the Accuracy of Cosmic Magnification Statistics
Brice Menard, Takashi Hamana, Matthias Bartelmann +1
The systematic magnification of background sources by the weak gravitational-lensing effects of foreground matter, also called cosmic magnification, is becoming an efficient tool b…
Measuring Omega_0 with higher-order Quasar-Galaxy Correlations induced by Weak Lensing
Brice Menard, Matthias Bartelmann, Yannick Mellier
Via the magnification bias, gravitational lensing by large-scale structures causes angular cross-correlations between distant quasars and foreground galaxies on angular scales of a…
Weak-Lensing Halo Numbers and Dark-Matter Profiles
Matthias Bartelmann, Lindsay King, Peter Schneider
Integral measures of weak gravitational lensing by dark-matter haloes, like the aperture mass, are sensitive to different physical halo properties dependent on the halo mass densit…
Weak Gravitational Lensing
Matthias Bartelmann, Peter Schneider
We review theory and applications of weak gravitational lensing. After summarising Friedmann-Lemaitre cosmological models, we present the formalism of gravitational lensing and lig…
