Description
In recent years observations of blank fields enabled us to detect galaxies as far as z~11. However, very little is known about those galaxies, and they are mostly the most luminous representatives. Observations with James Webb Space Telescope will revolutionize this field. In particular, grism spectrograph NIRISS provides observing modes for slitless spectroscopy, which will be unique in enabling unbiased selection of z > 7 galaxies in the grism data. Several clusters of galaxies, used as cosmic telescopes, will be observed. I will present results from the largest such survey CANUCS which identified new puzzles of star formation at z~7 and beyond.
