The ISW-Lensing Bispectrum & Trispectrum
Oliver H. E. Philcox, J. Colin Hill
Due to the integrated Sachs-Wolfe (ISW) effect, cosmic microwave background (CMB) temperature and polarization fluctuations are correlated with the gravitational lensing potential.…

Consistently constraining with the squeezed lensing bispectrum using consistency relations
Samuel Goldstein, Oliver H. E. Philcox, J. Colin Hill +2
We introduce a non-perturbative method to constrain the amplitude of local-type primordial non-Gaussianity () using squeezed configurations of the CMB lensing convergen…
