Galaxy Formation after z = 1000
Abstract
The `hierarchical clustering' and `pancake' theories for galaxy formation are reviewed. In spite of the considerable difference between these two schemes it is difficult to offer observational tests that might discriminate whether galaxies or clusters of galaxies formed first. Recent observations of the microwave background radiation spectrum suggest that we may be looking back to the time of galaxy formation, and future isotropy measurements below 1 mm may provide vital clues.
