Query: Constraints on Pre-Recombination Early Dark Energy from SPT-3G Public
  Data   Early dark energy (EDE) is a proposed solution to the Hubble tension in which
a new cosmological field accelerates cosmic expansion prior to recombination
and reduces the physical size of the sound horizon. In previous work, a slight
preference for a non-zero EDE contribution was found in the latest Atacama
Cosmology Telescope data (ACT DR4), while the Planck satellite legacy data
alone do not show evidence for it. In this work, we use the most recent public
data from the South Pole Telescope (SPT-3G) to constrain the parameters of the
EDE scenario. We find that at the current precision level of SPT-3G, an EDE
contribution to the total energy density of the universe prior to recombination
of $\sim 10\%$ can not be ruled out, but that the data are also consistent with
no EDE. The combination of ACT DR4 and SPT-3G with the Planck large-scale
temperature anisotropy measurement shows a hint ($2.6\sigma$) for non-zero EDE;
however, this preference disappears when the full Planck 2018 data set is
included.
