From etcs to simulated images to next steps

From ETCs to Simulated Images to next steps

Work to generate a set of simulated JWST images (spectra to follow)

of different astrophysical systems (e.g., a globular cluster, a deep galaxy field).

– These images can form “data challenges” to allow astronomers to work with

expected JWST data and form analysis tools.

– Simulated products will help evaluate STScI data reduction pipelines.

A Preliminary Example: An easy way to generate a simulated image


Stsci s role

Webb is not easy to use!

  • Multi-object spectroscopy

  • Coronography


Data challenges

Data Challenges

  • Data Challenges would be part of the joint learning process: the community can become familiar with JWST data sets and at the same time members of the community might discover improved ways for dealing with the data.

  • The challenge will consist in carrying out one or more complex measurements on the simulated data.

  • First challenge: An imaging data challenge, probably aimed at a JWST deep field

  • The second challenge will be a spectroscopic challenge and might be based on NIRSpec Micro-Shutter Assembly data or MIRI Integral Field Unit data.

MIRI IFU ground test data at 5.7-6.7 m and 8.7-10.3 m

If possible one could imagine additional challenges on, e.g. coronagraphs or transits.

Stsci s role

Some JWST Working groups at STScI

ETC (E. Barker) : developed the prototype ETC.

Efficiency (K. Gordon) : monitoring predicted observing efficiency for JWST, suggest improvements, maintain DRM.

Coronography (R. Soummer): study operational strategies for JWST coronographs.


Stsci s role

Cross-mission (HST-JWST) WGs

Slitless Grism : transfer experience from HST to JWST. Held conference

IR Detector Persistence : draw operational lessons for JWST from HST experience. Established WFC3/IR and JWST detectors behave differently.

Photometry : establish limiting factors to photometric accuracy and develop paths for improvement

User support and documentation : future trends in user support.


Jwst public outreach

JWST Public Outreach

The E/PO program must train educators and raise public awareness

about JWST’s unique scientific role in our understanding of the Universe

  • E/PO tools and exposures (STScI, GSFC, NGAS, CSA, and ESA)

  • News releases and media

  • printed materials

  • videos and 3D content

  • animations

  • dedicated websites

  • social media

  • blogs

  • exhibits and support materials (e.g., recent World Science Festival in NYC)

  • hard-copy and web-based curriculum support

  • professional development programming


Stsci s role

Webb’s outreach and education program will build upon Hubble’s success

informal

education

multimedia show currently exhibited

in 220 museums, science centers

and planetariums around the world

Online and hard-copy

materials are:

Used in all 50 states.

Used in 42 of the 100 largest school districts in the country.

Reach an estimated 6.3 million students per year.

Reach an estimated 506,000 pre- and in-service teachers.
