Self-Calibration for Three-Point Intrinsic Alignment Autocorrelations in Weak Lensing Surveys
The weak lensing signal (cosmic shear) has been shown to be strongly contaminated by the various types of galaxy intrinsic alignment (IA) correlations, which poses a barrier to precision weak lensing measurements. The ...
Growth of Structure in the Szekeres Class-II Inhomogeneous Cosmological Models and the Matter-Dominated Era
This study belongs to a series devoted to using the Szekeres inhomogeneous models in order to develop a theoretical framework where cosmological observations can be investigated with a wider range of possible interpretations. ...
Testing Gravity Theories Using Tensor Perturbations
(American Physical Society, 2016-12-21)
Primordial gravitational waves constitute a promising probe of the very early Universe and the laws of gravity. We study in this work changes to tensor-mode perturbations that can arise in various proposed modified gravity ...
