The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
A Topological Data Analysis of the CHIME/FRB Catalogues
Shruti Bhatporia, Anthony Walters, Jeff Murugan +1
In this paper, we use Topological Data Analysis (TDA), a mathematical approach for studying data shape, to analyse Fast Radio Bursts (FRBs). Applying the Mapper algorithm, we visua…
Antenna characterization for the HIRAX experiment
Emily R. Kuhn, Benjamin R. B. Saliwanchik, Kevin Bandura +24
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) aims to improve constraints on the dark energy equation of state through measurements of large-scale structure at h…
The Hydrogen Intensity and Real-time Analysis eXperiment: 256-Element Array Status and Overview
Devin Crichton, Moumita Aich, Adam Amara +97
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio interferometer array currently in development, with an initial 256-element array to be deployed at the S…
Probing Diffuse Gas with Fast Radio Bursts
Anthony Walters, Yin-Zhe Ma, Jonathan Sievers +1
The dispersion measure -- redshift relation of Fast Radio Bursts, , has been proposed as a potential new probe of the cosmos, complementary to existing techniques.…
Fast Radio Burst Cosmology and HIRAX
Amanda Weltman, Anthony Walters
Until very recently we had as many theories to explain Fast Radio Bursts as we have observations of them. An explosion of data is coming, if not here already, and thus it is an opp…
A Living Theory Catalogue for Fast Radio Bursts
E. Platts, A. Weltman, A. Walters +3
At present, we have almost as many theories to explain Fast Radio Bursts as we have Fast Radio Bursts observed. This landscape will be changing rapidly with CHIME/FRB, recently com…
Future Cosmological Constraints from Fast Radio Bursts
Anthony Walters, Amanda Weltman, B. M. Gaensler +2
We consider the possible observation of Fast Radio Bursts (FRBs) with planned future radio telescopes, and investigate how well the dispersions and redshifts of these signals might…
Calculating Observables in Inhomogeneous Cosmologies I: General Framework
Charles Hellaby, Anthony Walters
We lay out a general framework for calculating the variation of a set of cosmological observables, down the past null cone of an arbitrarily placed observer, in a given arbitrary i…
How to Avoid a Swift Kick in the Chameleons
Antonio Padilla, Emma Platts, David Stefanyszyn +3
Recently it was argued that the conformal coupling of the chameleon to matter fields created an issue for early universe cosmology. As standard model degrees of freedom become non-…
