First, it provides spectra for every object in the field of view; because no preselection for the placement of slits is required, it dramatically expands the potential discovery space. Second, instead of a single unresolved spectrum for each object, it yields spatially resolved maps of line emission in addition to velocity fields. The JWST Cycle 1 FRESCO program is using this capability to conduct the “First Reionization Epoch Spectroscopically COmplete” Survey (who doesn’t love a tortured acronym) which will provide spectra for >300 galaxies in the cosmic dark ages (z~7-9) and 1200 in the epoch of reionization (z~5-6.5). Having pioneered the method, I am the leader in the measurement and interpretation of resolved properties of ionized gas from space-based slitless spectroscopy (Nelson et al. 2012). With emission line maps from FRESCO, we will be able to determine how galaxies grew during the epoch of reionization at z>6, the first measurements of their kind. With much smaller separations between galaxies at these early cosmic times, do galaxies build through merger-induced central starbursts or inside-out as a result of accretion of gas from the cosmic web? https://images.squarespace-cdn.com/content/v1/582437112e69cfc8ac1ce6b7/66d757ea-8098-44ce-8c6f-499ecd51eaa2/UNCOVER_logo_black.png Research Ultra-deep Nirspec and nirCam ObserVations before the Epoch of Reionization to find the first galaxies deep into the dark ages.

This illustration reveals the celestial fireworks deep inside the crowded core of a developing galaxy, as seen from a hypothetical planetary system. The sky is ablaze with the glow from nebulae, fledgling star clusters, and stars exploding as supernovae. The rapidly forming core may eventually become the heart of a mammoth galaxy similar to one of the giant elliptical galaxies seen today. Credit: NASA, Z. Levay, and G.
