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…
