Abstract:
Understanding galaxy formation is one of the most pressing issues in
cosmology. We review the current status of galaxy formation from both
an observational and a theoretical perspective, and summarize the
prospects for future advances.
Keywords: galaxy: formation — galaxies: evolution —
galaxies: star formation — galaxies: active
