Gravitational lensing in galaxy redshift surveys
Gravitationally-lensed quasars are both valuable (individually and statistically) and rare. They are mostly discovered through time-consuming re-imaging of known quasars, but can also be found spectroscopically in galaxy redshift surveys. Q 2237+0305 (Huchra et al. 1985) was found in this manner, but remains the only such discovery. Kochanek (1992) predicted that ∼ 1 in 10 redshifts would yield...
متن کاملCluster detection in weak lensing surveys
We present an efficient and robust approach for extracting clusters of galaxies from weak lensing survey data and measuring their properties. We use simple, physically-motivated cluster models appropriate for such sparse, noisy data, and incorporate our knowledge of the cluster mass function to optimise the detection of low-mass objects. Despite the method’s non-linear nature, we are able to se...
متن کاملCosmology with weak lensing surveys.
Weak gravitational lensing is responsible for the shearing and magnification of the images of high-redshift sources due to the presence of intervening mass. Since the lensing effects arise from deflections of the light rays due to fluctuations of the gravitational potential, they can be directly related to the underlying density field of the large-scale structures. Weak gravitational surveys ar...
متن کاملIntrinsic galaxy alignments from the 2SLAQ and SDSS surveys: luminosity and redshift scalings and implications for weak lensing surveys
Correlations between intrinsic shear and the density field on large scales, a potentially important contaminant for cosmic shear surveys, have been robustly detected at low redshifts with bright galaxies in SDSS data. Here we present a more detailed characterization of this effect, which can cause anti-correlations between gravitational lensing shear and intrinsic ellipticity (GI correlations)....
متن کاملWeak Lensing Surveys and the Intrinsic Correlation of Galaxy Ellipticities
We explore the possibility that an intrinsic correlation between galaxy ellipticities arising during the galaxy formation process may account for part of the shear signal recently reported by several groups engaged in weak gravitational lensing surveys. Using high resolution N-body simulations we measure the projected ellipticities of dark matter halos and their correlations as a function of pa...
