On Weak Lensing Response Functions
D. Munshi, R. Takahashi, J. D. McEwen
We introduce the response function (RFs) approach to model the weak lensing statistics in the context of separate universe formalism. Numerical results for the RFs are presented fo…
Weak Lensing Trispectrum and Kurt-Spectra
Dipak Munshi, Hayden Lee, Cora Dvorkin +1
We introduce two kurt-spectra to probe fourth-order statistics of weak lensing convergence maps. Using state-of-the-art numerical simulations, we study the shapes of these kurt-spe…
A New Estimator for Phase Statistics
D. Munshi, R. Takahashi, J. D. McEwen +2
We introduce a novel statistic to probe the statistics of phases of Fourier modes in two-dimensions (2D) for weak lensing convergence field . This statistic contains completely…
Position-Dependent Correlation Function of Weak Lensing Convergence
D. Munshi, G. Jung, T. D. Kitching +4
We provide a systematic study of the position-dependent correlation function in weak lensing convergence maps and its relation to the squeezed limit of the three-point correlation…
The integrated angular bispectrum of weak lensing
Gabriel Jung, Toshiya Namikawa, Michele Liguori +2
We investigate three-point statistics in weak lensing convergence, through the integrated bispectrum. This statistic involves measuring power spectra in patches, and is thus easy t…
Morphology of Weak Lensing Convergence Maps
D. Munshi, T. Namikawa, J. D. McEwen +2
We study the morphology of convergence maps by perturbatively reconstructing their Minkowski Functionals (MFs). We present a systematics study using a set of three generalised skew…
