Title: Understanding the Nature of Submillimeter Galaxies with Gas Kinematics

Abstract: Submillimeter galaxies (SMGs) are the most extreme star-forming galaxies in the universe, and they are most likely the progenitors of massive elliptical galaxies today. But our knowledge of this important high-redshift galaxy population has been limited by the sensitivity and spatial resolution of current instrumentation. We propose to exploit the power of gravitational lensing to examine SMGs at a level of detail that is otherwise unattainable. With GMOS/IFU, we propose to measure the distributions and kinematics of the ionized gas in a bright, strongly lensed SMG at z = 1. Combined with our lens model and existing multi-wavelength data sets, these kinematics data will shed new light on the formation of SMGs, because they will enable us to distinguish between merger-triggered starbursts and extended quiescent mode of star formation --- the two competing scenarios to explain the prolific star formation in SMGs.
