Spiral Galaxy Kinematics Over the Last 8 Gyr

Susan Kassin, Oxford University

Abstract
Observations of the internal kinematics of local galaxies have played a key role in the development of our current scenario for galaxy formation. Recently, it has become possible to measure the internal kinematics of large samples of galaxies (~500 to ~25,000) to high redshift (z~1). I will present new results from studies of galaxy kinematics over 0.1 < z < 1.5 using data from the DEEP2 Survey and discuss how they inform our picture of galaxy formation. The focus of this talk will be on two studies: the relation between galaxy stellar mass and rotation velocity (the stellar mass Tully-Fisher relation), and the distribution of galaxy line widths (the galaxy velocity function).
