Description
We present number densities and physical properties of galaxies spectroscopically confirmed with JWST up to z~14. The UV luminosity functions determined with the spectroscopic galaxy sample are consistent with the photometric results from previous studies, and show a tension with most of the theoretical model predictions. We will discuss several possibilities that can explain the observed overabundance of bright galaxies at z>10. We also present JWST discoveries of abundant AGN populations at z>4 and their physical properties, important to understand the nature of these newly-found objects.
