Roman Exoplanet Imaging Data Challenge Jamboree banner


The ROMAN Exoplanet Imaging Data Challenge ran for 8 months in 2019-2020. Organized by the Turnbull Science Investigation Team (SIT), this data challenge was a unique opportunity for exoplanet scientists of all backgrounds and experience levels to get acquainted with realistic Roman CGI (coronagraphic) simulated data with a new contrast regime enabling to unveil giant planets in reflected light.

Participants had to recover the astrometry of an exoplanetary system combining precursor radial velocity data with up to 6 coronagraphic imaging epochs throughout the mission. They had to perform accurate orbital fitting and determine the mass of any planet hidden in the data. It involved PSF subtraction techniques, post-processing, and other astrophysics hurdles to overcome such as contamination sources (stellar, extragalactic, and exozodiacal light).

We are now ready to announce the results to the community, present our in-house analysis, and discuss lessons learned and paths forward to best exploit scientifically the data coming out of Roman CGI. For that, we welcome you to attend our 3 ½ hour event on Friday, April 30 2021. The event will be publicly live-streamed on STScI Live Science Events channel (no need to have Facebook account). 


This event will be live-streamed.

All times listed are EDT.
