Flaglets for studying the large-scale structure of the Universe
Boris Leistedt, Hiranya V. Peiris, Jason D. McEwen
Pressing questions in cosmology such as the nature of dark matter and dark energy can be addressed using large galaxy surveys, which measure the positions, properties and redshifts…
Fourier-Laguerre transform, convolution and wavelets on the ball
J. D. McEwen, B. Leistedt
We review the Fourier-Laguerre transform, an alternative harmonic analysis on the three-dimensional ball to the usual Fourier-Bessel transform. The Fourier-Laguerre transform exhib…
Estimating the large-scale angular power spectrum in the presence of systematics: a case study of Sloan Digital Sky Survey quasars
Boris Leistedt, Hiranya V. Peiris, Daniel J. Mortlock +2
The angular power spectrum is a powerful statistic for analysing cosmological signals imprinted in the clustering of matter. However, current galaxy and quasar surveys cover limite…
Flaglets: Exact Wavelets on the Ball
Boris Leistedt, Jason D. McEwen
We summarise the construction of exact axisymmetric scale-discretised wavelets on the sphere and on the ball. The wavelet transform on the ball relies on a novel 3D harmonic transf…
