OpenUniverse 2024 Simulated Roman & Rubin Images: Preview

Overview

OpenUniverse2024 is a project to simulate spatially overlapping imaging surveys to be carried out by the Nancy Grace Roman Telescope and the Vera C. Rubin Observatory. The simulations were carried out on Argonne's Theta cluster and consist of:

  1. The LSST ELAIS-S1 Deep Drilling Field (DDF)
  2. The Roman Time-Domain Survey (TDS) shifted to overlap the ELAIS region and LSST DDF
  3. Overlapping LSST Wide-Fast-Deep (WFD) survey (with rolling cadence)
  4. Overlapping Roman Wide-Area Survey (WAS) in the same region
  5. A deep-field calibration region of the Roman WAS in the same region

This data preview release consists of a subset of data from each of the five categories above.
