About The Workshop

Spectroscopic observations from the James Webb Space Telescope (JWST) will be a powerful tool for probing the physics of galaxy formation. Emission-line measurements will provide important diagnostics of galaxy chemical composition, star-formation rates, feedback, stellar populations, and photo-ionizing continuum escape.  Recent spectroscopic observations of high redshift galaxies have revealed that new ingredients are required to model the spectral energy distributions of low metallicity galaxies, and to interpret the nebular spectra observed in the extreme emission-line galaxies. New spectral diagnostics based on rest-frame UV and optical emission lines have been developed that can take advantage of the wavelengths accessible for JWST spectroscopy of galaxies at z>7. There has been progress made on calibrating indirect probes of the conditions that facilitate the escape of ionizing photons using local galaxies. At the same time, theoretical studies have made significant advances in modeling the feedback and outflows in galaxies, and radiative transfer in the IGM at early epochs. This workshop aims to bring together expert observers and theorists to discuss the spectral diagnostics and efficient strategies to maximize the JWST science for exploring high-redshift galaxies.

Topics to be covered include:

• Observed properties of high redshift emission-line galaxies
• Observed properties of low redshift emission-line galaxies
• Lyman-alpha emission, visibility, profile shapes
• UV Continuum, ionizing photon production rate
• Spectral diagnostics for revealing the nature of ionizers
• Feedback, outflow geometry, and escape of ionizing radiation
• Stellar population, gas and dust in extreme emission line galaxies

The workshop will include invited talks, contributed talks, and posters. On the last day of the workshop there will also be breakout sessions scheduled to demonstrate JWST proposal planning tools (APT, ETC) and data analysis tools to help with the JWST observation planning.
