The One-Loop Power Spectrum of Fast Radio Burst Dispersion Measures
Haruki Ebina, Martin White
Fast radio burst (FRB) dispersion measures trace free electron column densities and will soon offer a unique probe of low- baryons. Such measurements can constrain cosmology dir…

An Analytically Tractable Marked Power Spectrum
Haruki Ebina, Martin White
The increasing precision of cosmology data in the modern era is calling for methods to allow the extraction of non-Gaussian information using tools beyond two-point statistics. The…

The Bispectrum in Lagrangian Perturbation Theory
Shi-Fan Chen, Zvonimir Vlah, Martin White
We study the bispectrum in Lagrangian perturbation theory. Extending past results for the power spectrum, we describe a method to efficiently compute the bispectrum in LPT, focusin…
