JWST Community Lecture Series - Wide-Field Slitless Spectroscopy with the James Webb Space Telescope (G. Brammer)

Community Lecture
April 11, 2017 11:00 AM EDT - April 11, 2017  12:00 PM EDT
Baltimore STScI Muller Auditorium

Abstract:

I will review the wide-field slitless spectroscopic (WFSS) capabilities of the JWST instruments NIRISS and NIRCam.  Using a grism element and no slits, JWST WFSS will probe parameter space intermediate between standard imaging and IFU and multi-object spectroscopy observing modes, providing uniform spectra of large, unbiased samples of stars and galaxies that can be used to measure spectral types, redshifts, and spatially-resolved emission line diagnostics.  However, with no slits, the overlapping spectra of neighboring objects must be carefully modeled in order to robustly extract this information.  I will review some recent science results and analysis challenges from HST WFSS programs, and use them to demonstrate tools that can be used for simulating and analyzing future JWST observations.
