| Abstract: |
Simple models of galaxy formation based on homologous collapse and constant mass-to-light ratio predict significant changes in disk structural parameters to z~1. This paper presents a review of attempts to date to detect such changes. They are proving hard to measure, owing to two serious selection effects in existing samples. Nonetheless, if present results are indicative, the amount of evolution to z~1 appears to be somewhat smaller than expected. One way to match both the small degree of evolution as well as the slow rotation of local galaxies in the Tully-Fisher relation is to reduce both the total angular momentum share of the disk baryons, together with the concentration parameter of dark halos. |
