| Summary:
The third data release (DR3) of Gaia has provided a five-fold increase in the
number of radial velocity measurements of stars, as well as a stark improvement
in parallax and proper motion measurements. To help with studies that seek to
test models and interpret Gaia DR3, we present nine Gaia synthetic surveys,
based on three solar positions in three Milky-Way-mass galaxies of the Latte
suite of the Fire-2 cosmological simulations. These synthetic surveys match the
selection function, radial velocity measurements, and photometry of Gaia DR3,
adapting the code base Ananke, previously used to match the Gaia DR2 release in
Sanderson et al. 2020. The synthetic surveys are publicly available and can be
found at http://ananke.hub.yt/. Similarly to the previous release of Ananke,
these surveys are based on cosmological simulations and thus able to model
non-equilibrium dynamical effects, making them a useful tool in testing and
interpreting Gaia DR3.
