Interacting with Roman

Core Community Survey Definition process


Each of the Core Community Surveys will provide data to many teams conducting a large number of diverse science investigations. Roman’s science objectives that will be addressed by the Core Community Surveys are Astrophysics with wide area near-IR surveys, Cosmology and Exoplanet demographics.

Given the broad range of science topics that each survey will address, the Roman mission plans to define the core surveys via an open collaborative process implemented by the Roman science centers at STScI and IPAC. The goal is to maximize the science return from the core surveys while also providing the observations needed to meet science requirements in Cosmology and Exoplanet Demographics.

The goal is for the core surveys to be community defined in a broad inclusive process with a large number of groups with diverse science interests providing input into the survey design. The surveys will be community owned, they will not be directed by a single team, and there is no proprietary period for any Roman science data.

- Core Community Surveys -

Galactic Bulge Time Domain Survey

Galactic Bulge Time Domain Survey

Galactic Bulge Time Domain Survey

  • ~<15 min cadence observations over few deg2 towards galactic bulge
  • Enables exoplanet microlensing mission objectives

High Latitude Time Domain Survey

High Latitude Time Domain Survey

High Latitude Time Domain Survey

  • Tiered, multiband time domain observations of 10s of deg2 at high latitudes

High Latitude Wide Area Survey

High Latitude Wide Area Survey

High Latitude Wide Area Survey

  • Wide area multiband survey with slitless spectroscopy
  • Enables weak lensing and galaxy redshift cosmology mission objectives

Timeline and outline of survey definition process

Information sessions to inform community about Roman capabilities

  • Outline available parameter space for each survey
  • Constraints are that each survey provides data needed to meet the science requirements, and at least 25% time (TBC) is retained for General Astrophysics Surveys

White paper call for papers detailing science that can be done with the survey

  • Encourage development of metrics/figures of merit, and description of specific observational needs
  • Workshops to enable community cooperation and consensus
  • Provides a forum for iterative development of survey concepts

Evaluation and Recommendations

Set up and charter a tiered committee structure to do the work of recommending survey definitions based on community input. Committees include representatives of all science areas to be addressed by each survey (determined from white paper submissions etc).

Steering Committee: Provides recommendations on balance between each of the core community surveys, and the general astrophysics survey allocation above 25%

Survey Committee: Evaluate white papers, solicit additional community input, evaluate survey options against science metrics, produce recommendations for survey with options for enhancements/descopes

Engaging with Roman on technical and science topics

Technical working groups that cut across all science areas

  • Forum for people to work together on topics/methods that cut across science areas
  • Brings together Science community, science centers, and project
List of Calibration, Astronomy, Software, Simulations, Detectors, and Spectroscopy

* Not all groups are currently active

Community led Science Collaborations

  • Enable people to engage with Roman science independently of NASA-selection
  • Facilitate the formation of quasi-independent community-led consortia
  • Definition of these is currently vague, because we want to work with the community to shape what these should be.
