Probing dark energy with redshift-drift
  Future redshift-drift measurements (also known as Sandage-Loeb signal) will
be crucial to probe the so called "redshift desert", thus providing a new tool
for cosmological studies. In this paper we quantify the ability of a future
measurement of the Sandage-Loeb signal by a CODEX-like spectrograph to
constrain a phenomenological parametrization of dynamical dark energy,
specifically by obtaining constraints on $w_0$ and $w_a$. We also demonstrate
that if used alongside CMB data, the Sandage-Loeb measurements will be able to
break degeneracies between expansion parameters, thus greatly improving
cosmological constraints.
