Despite the first detection of fast radio bursts (FRBs) being as recent as 2007, they have already been proven to be a fantastic tool as a unique cosmological probe. In this chapter, after a brief introduction to FRBs and how they are currently detected, we describe various cosmological questions and how FRB research has both aided previous studies and can continue to do so. Topics include placing constraints on cosmological parameters to understanding the distribution of baryons throughout the Universe. We conclude with some notes on the challenges to be overcome and how to best enable ongoing and future FRB-based studies of cosmology.

  1. Testing the Isotropy of the Universe with the CHIME/FRB Catalog I

    astro-ph.HE 2026-07 conditional novelty 6.0 of 10

    A 536-burst CHIME FRB sample shows no statistically significant directional anisotropy, though the test's constraining power is limited.

  2. A Neural Network Model for the Cosmic Dispersion Measure in the CAMELS Simulations

    astro-ph.CO 2025-01 conditional novelty 6.0 of 10

    A neural network emulator trained on CAMELS simulations predicts FRB dispersion measure distributions and reveals non-monotonic dependence of the scatter parameter F on galaxy feedback parameters.

  3. Pad\'e Approximants for cosmic Dispersion Measures

    astro-ph.HE 2025-12 conditional novelty 4.0 of 10

    Padé approximants reproduce the FRB diffuse dispersion measure integral to within a few percent while evaluating 2–17 times faster than numerical quadrature.
