Title: Gas morpholigies and dyamics of SMGs; comparing the ionized and molecular gas
Abstract:
We propose to use NIFS to observe 12 Sub-Millimeter Galaxies (SMGs) which
have already been mapped in various transitions of CO from the Bothwell et
al. (2012) sample. We will trace the Halpha and [NII] emission lines within
the sources, mapping the gas morphologies, dynamics and metallicities. We
will compare the ionized and molecular gas components in these SMGs, and test
the hypothesis that the extreme star formation observed in these systems is
triggered by multiple components merging together. The proposed targets
already have high resolution interferometric CO observations available
allowing a detailed study of the complicated gas processes occurring in these
extreme systems and the link between the ionized and molecular gas. The broad
redshift range of the target sample also allows for an investigation into the
evolution of the trigger of the intense star formation in SMGs, probing if
this burst is an extremely active phase in the formation of the massive
ellipticals observed today.
