Gauge-Invariant Formalism of Cosmological Weak Lensing
TL;DR: In this article, the authors present the gauge-invariant formalism of cosmological weak lensing, accounting for all the relativistic effects due to the scalar, vector, and tensor perturbations at the linear order.
Journal ArticleDOI
Galaxy power spectrum in general relativity
TL;DR: In this article, the galaxy power spectrum in general relativity was derived by taking into account all the relativistic effects in observations. But the results of this paper are not applicable to the analysis of large-scale data.
Journal ArticleDOI
Gauge-Invariant Formalism of Cosmological Weak Lensing.

Journal ArticleDOI
Jacobi mapping approach for a precise cosmological weak lensing formalism
Nastassia Grimm,Jaiyul Yoo +1 more
TL;DR: In this article, the Jacobi mapping formalism is used to describe all the relativistic effects contributing to the weak lensing observables, including scalar, vector and tensor perturbations.
Journal ArticleDOI
Cutting out the cosmological middle man: general relativity in the light-cone coordinates
TL;DR: In this paper, a light-cone-adapted version of the Friedmann-Lemaitre-Robertson-Walker (FLRW) coordinates is presented and a subset for cosmological perturbation theory is constructed.
