Title: Evidence against Ryskin's model of cosmic acceleration

Abstract

In this paper I examine how well Ryskin’s model of emergent cosmic acceleration fits several sets of cosmological observations. I find that while Ryskin’s model is somewhat compatible with the standard model of cosmological acceleration (ΛCDM) for low redshift (z ≲ 1) measurements, its predictions diverge considerably from those of the standard model for measurements made at high redshift (for which z ≳ 1), and it is therefore not a compelling substitute for the standard model.
