Description
The James Webb Space Telescope (JWST) is unveiling astounding results about the first few hundred million years of life of the Universe, delivering images of galaxies at very high redshifts. We develop a UV luminosity function model for high-redshift galaxies, considering parameters such as the stellar formation rate, dust extinction, and halo mass function. Testing the model against data at higher redshifts reveals successful accommodation of the data at z = 8-9, but challenges emerge at z~13. We explore the possibility that this can be explained in terms of the existence of exotic objects at high redshift.
