Gravitational shearing
The WL shear caused by gravitational light deflection from foreground mass concentrations, modified by dimensionless cosmic distance ratios -- both of which are sensitive to dark energy -- naturally fall into two regimes, suggesting two methods of data analysis and interpretation: Method 1: Operate … See more Weak lensing is a powerful probe of cosmological models, beautifully complementary to those that have given rise to the current standard model of cosmology. The … See more There is information beyond tangential shear. The shear is a spin-2 field and consequently we can measure two independent … See more Weak gravitational lensing maps source galaxies to new positions on the sky, systematically distorting their images. The resulting shear γ of … See more Weak lensing has high information content. A big advantage for WL over CMB is Tomography. The rich cosmological harvest from CMB comes from a single redshift … See more WebPhysical Weathering Processes. Physical or mechanical weathering processes depend on some applied forces. The applied forces could be- (i) gravitational forces such as overburden pressure, load and shearing stress; (ii) expansion forces due to temperature changes, crystal growth or animal activity; (iii) water pressures controlled by wetting and …

Gravitational lensing acts as a coordinate transformation that distorts the images of background objects (usually galaxies) near a foreground mass. The transformation can be split into two terms, the convergence and shear. The convergence term magnifies the background objects by increasing their size, and the shear term stretches them tangentially around the foreground mass. WebImages of faint galaxies are subject to gravitational shearing, followed by smearing with the instrumental and/or atmospheric PSF. We construct a ``finite-resolution shear operator,'' which when applied to an observed image has the same effect as a gravitational shear applied prior to smearing.
