Invited Presentation

Imaging Molecular Gas in the Distant Universe with ALMA Band 1

Author(s): Justin Spilker, University of Arizona; South Pole Telescope Submillimeter Galaxy Collaboration

Presenter: Justin Spilker (University of Arizona)

One of the key motivations for the installation of Band 1 receivers on ALMA is the study of molecular gas using low-excitation transitions of CO in high-redshift objects. I will focus in particular on the prospects for spatially resolving the gas reservoirs in distant galaxies. We have conducted ATCA observations of low-J CO emission from a number of gravitationally lensed dusty star-forming galaxies at z=2-6 selected from the South Pole Telescope 2500deg^2 survey which spatially resolve the CO at ~0.5" resolution. I will highlight results from this program and outline areas of expected improvement from the greatly enhanced sensitivity and imaging capabilities of Band 1 receivers on ALMA.
