| Abstract: |
Size is a fundamental parameter in our understanding of galaxy formation. The first galaxies- small, low mass disks grow to the large, structured galaxies of the present day through repeated mergers. Observations of large, massive disk galaxies at redshifts between 1.5 and 3 pose an interesting challenge to the hierarchical picture. The FIRES survey (Labbkpcé et al. 2003) reveals that these galaxies have sizes comparable (or possibly larger) than the Milky Way. How did mass assemble into such large galaxies only 2 − 3 Gyr after the Big Bang? In this project, we aim to characterize the dynamical state of these large disks. Here, we present our preliminary results- using near infrared spectroscopic data from the 8-m Gemini South Telescope, we discuss aspects of star formation and the followup work we have planned for these objects. |
