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…
Linking the Singularities of Cosmological Correlators
Daniel Baumann, Wei-Ming Chen, Carlos Duaso Pueyo +3
Much of the structure of cosmological correlators is controlled by their singularities, which in turn are fixed in terms of flat-space scattering amplitudes. An important challenge…
Precise and Accurate Cosmology with CMBxLSS Power Spectra and Bispectra
Shu-Fan Chen, Hayden Lee, Cora Dvorkin
With the advent of a new generation of cosmological experiments that will provide high-precision measurements of the cosmic microwave background (CMB) and galaxies in the large-sca…
