Can Late Dark Energy Transitions Raise the Hubble constant?
  Late times dark energy transitions at redshifts $z \ll 0.1$ can raise the
predicted value of the Hubble constant to the SH0ES value, $74.03\pm 1.42$ (km
s$^{-1}$ Mpc$^{-1})$ or more, while providing an equally good fit as
$\Lambda$CDM at $67.73 \pm 0.41$ to higher redshift data, in particular from
the cosmic microwave background and baryon acoustic oscillations. These models
however do not fully resolve the true source of tension between the distance
ladder and high redshift observations: the local calibration of supernovae
luminosities well out into the Hubble flow. When tested in this manner by
transferring the SH0ES calibration to the Pantheon supernovae dataset, the
ability of such transitions to raise the Hubble constant is reduced to $69.17
\pm 1.09$. Such an analysis should also be used when testing any dynamical dark
energy model which can produce similarly fine features in redshift or local
void models.
