A pilot HI survey of SAMI galaxies

In the last decade, tremendous progress has been made in our understanding of galaxies, thanks to large spectroscopic surveys at optical and radio wavelengths. The next-generation optical spectroscopy surveys with Integral Field Units (IFUs) will further advance extragalactic studies by providing spatially-resolved maps of stellar and ionized gas properties for a few thousands galaxies. Here we propose a pilot program to measure the global HI properties of 66 galaxies observed by the on-going SAMI IFU Galaxy Survey, which has already assembled the largest sample of IFU maps for nearby galaxies. These observations will demonstrate the power of the combination of IFU and integrated HI data to gain insights into the life cycle of galaxies. Our immediate ob jectives are to address key science questions, including identifying a unified dynamical scaling relation for all galaxies, investigating the impact of HI on metallicity profiles, and correlating outflows with cold gas content. Outreach Abstract: Galaxies are collections of hundreds of billions of stars formed out of the gaseous matrix that permeated the early Universe. Despite tremendous progress in our understanding of galaxies, we still lack a clear picture of the role played by the gas component - the fuel for future star formation. This program combines state-of-the-art optical observations (which map star formation, kinematics and chemical enrichment in galaxies) to observations from the Arecibo radio telescope (which measure the gas content), in order to gain important insights into the physical processes regulating the evolution of galaxies in the local Universe.
