Could We Be Fooled about Phantom Crossing?

Ryan E. Keeley, Arman Shafieloo, William L. Matthewson

Recent data from DESI Year 2 BAO, Planck CMB, and various supernova compilations suggest a preference for evolving dark energy, with hints that the equation of state may cross the…

JWST lensed quasar dark matter survey I: Description and First Results

A. M. Nierenberg, R. E. Keeley, D. Sluse +18

The flux ratios of gravitationally lensed quasars provide a powerful probe of the nature of dark matter. Importantly, these ratios are sensitive to small-scale structure, irrespect…

Early or phantom dark energy, self-interacting, extra, or massive neutrinos, primordial magnetic fields, or a curved universe: An exploration of possible solutions to the $H_{0}$ and $σ_{8}$ problems

Helena García Escudero, Jui-Lin Kuo, Ryan E. Keeley +1

In this paper we explore the existing tensions in the local cosmological expansion rate, $H_{0}$ , and amplitude of the clustering of large-scale structure at $8 h^{- 1} Mpc$ …
