Weak Lensing by Large-Scale Structure: A Dark Matter Halo Approach.
Weak gravitational lensing observations probe the spectrum and evolution of density fluctuations and the cosmological parameters that govern them, but they are currently limited to small fields and subject to selection biases. We show how the expected signal from large-scale structure arises from the contributions from and correlations between individual halos. We determine the convergence powe...
متن کاملSimulating Weak Lensing by Large Scale Structure
We model weak gravitational lensing of light by large-scale structure using ray tracing through N-body simulations. The method is described with particular attention paid to numerical convergence. We investigate some of the key approximations in the multi-plane ray tracing algorithm. Our simulated shear and convergence maps are used to explore how well standard assumptions about weak lensing ho...
متن کاملWeak-lensing Halo Numbers and Dark-matter Profiles
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 density profile. For isothermal profiles, the relation between aperture mass and virial mass is steeper than for haloes with the universal NFW profile. Consequently, the halo mass range probed by the aperture mass is much w...
متن کاملDark Matter Halo Detection in Weak Lensing Regimes
Although current methods exist to predict the location of these centers given comprehensive amounts of data such as three-dimensional position, mass, etc., there are not many approaches to finding the centers given two-dimensional images of a sky. However, for many regions of space, the only data collected are two-dimensional images, and thus the dark matter structures in those regions of space...
متن کاملWeak lensing, dark matter and dark energy
Weak gravitational lensing is rapidly becoming one of the principal probes of dark matter and dark energy in the universe. In this brief review we outline how weak lensing helps determine the structure of dark matter halos, measure the expansion rate of the universe, and distinguish between modified gravity and dark energy explanations for the acceleration of the universe. We also discuss requi...
