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.
