synthetic Gaia surveys of Latte simulations

Excited to announce the release of our synthetic Gaia DR2-like surveys from our Latte suite of FIRE-2 cosmological simulations of Milky Way-mass galaxies. We generated 9 synthetic surveys from 3 Latte simulations, using 3 solar viewpoints per simulation.  Along with these synthetic surveys, we also released full simulation snapshots at z = 0, including all particle data, from 3 Latte simulations. All data is available at , and our release paper is Sanderson et al 2018.

Congratulations to Robyn Sanderson for leading this ambitious effort, including developing our new Ananke framework for generating synthetic surveys from baryonic simulations. Congratulations also to the whole FIRE collaboration, and thanks to Kacper Kowalik and Matt Turk for tremendous help in hosting this data via the awesome .

We hope that these fully cosmological synthetic Gaia DR2-like surveys will provide useful tools to the scientific community in interpreting the amazing data of the Milky Way from the Gaia mission.
