The Roman Galaxy Redshift Survey Project Infrastructure Team

The Nancy Grace Roman Space Telescope is NASA's next flagship mission in astrophysics. The Roman Galaxy Redshift Survey Project Infrastructure Team (GRS PIT) develops and maintains the infrastructural tools and capabilities needed to address the mission objective for the Roman GRS and to support community science collaborations. We work closely with the Roman project, and partner with the Science Centers, providing all necessary support to ensure mission success.

Scope of Work

Our work plan is designed to simulate the data, model and optimize the observing program, model systematic errors and develop methods to mitigate them, and measure compressed statistics including the 2-point correlation function and power spectrum, as well as higher-order statistics uniquely enabled by Roman GRS’s high galaxy number density. Our deliverables include simulated and value-added galaxy catalogs, covariance matrices, and a set of ready-to-apply models calculated using different cutting-edge approaches. Our infrastructure work will enable robust measurements of Baryon Acoustic Oscillations (BAO) and Redshift Space Distortions (RSD), meeting the Roman science objectives for the GRS. Our modular approach allows the community to complement and extend this work in further science directions.

Data Products

We will release data products on an approximately annual basis to support the Roman Project and community science. Our NASA funded work begins on October 1, 2023.

If you need Roman simulated data products for the Galaxy Redshift Survey now, you can check out the data products from the previous work by some of our team members in 2021 and 2022, released by IRSA in 2022.
