visual outline of the three key steps of going from detector pixels to stellar spectra, from stellar spectra to fitted planetary features, and from fitted planetary features to inferred properties of planetary atmospheres

Spring 2022:
ERS Post-Launch Data Challenge #1: Simulated Data

The Transiting Exoplanet Community ERS team is conducting a data challenge exercise based on simulated data during the JWST commissioning period. The event will be held March 21-23, 2022 in-person at Baltimore, MD, USA and Heidelberg, Germany, with opportunities for remote participation.

Future Workshops

We plan to hold two data challenge workshops after JWST's launch both (1) to test instrument-specific analysis and interpretation tools on end-to-end simulations of the ERS datasets and (2) to present and compare independent analyses of the actual Early Release Science observations. The dates of these meetings were planned to be tied to JWST's launch, which happened in December 2021.

  • The ERS Pre-Launch Data Hackathon (2021) was held June 21-25, 2021 online, offering an opportunity for scientists to start engaging with simulated Webb transiting exoplanet data, learn from pedagogical talks on approaches to data analysis, and complete hands-on tutorials. Slides, recordings, code notebooks, and a Webb-friendly Python conda environment are all available at the above link.
  • The ERS Pre-Launch Theory Webbinar (2021) held weekly sessions throughout July and August 2021, offering an opportunity for scientists to learn about the basic theoretical concepts necessary for interpreting Webb transiting exoplanet atmosphere observations. Descriptions of the talks are available at the above link, and tutorial materials can be accessed through the ERS team slack.
  • The Enabling Transiting Exoplanet Observations with JWST (2017) workshop was held July 10-12, 2017 at STScI. Conversations at this meeting contributed to the organization and mobilization of our large community team to draft the Early Release Science proposal, as summarized in Bean et al. (2018).
  • The Enabling Transiting Exoplanet Science with JWST (2015) workshop was held November 16-18, 2015 at STScI. Conversations at this meeting contributed to the initial identification appropriate targets for the Early Release Science program, as summarized in Stevenson et al. (2016).
