 Abstract: The gas recycling process in galaxies is very poorly understood even though it is fundamental to how galaxies assemble their mass and evolve. Furthermore, the star formation processes in galaxies can be strongly affected by galactic winds (outflow), accretion of gas into the galaxy (inflow), environment (e.g. galaxies in groups or clusters), and mergers. It is still unknown which of these processes/effects are the main drivers in the evolution of galaxies. To have a complete picture of how galaxies process their gas and evolve, we need information at different wavelengths for large samples of galaxies, as well as detailed spatial information as given by Integral Field Spectroscopy (IFU).
I will talk about an ongoing project analyzing the gas metallicity and star formation rate of galaxy groups using data form the GAMA (Galaxy And Mass Assembly) survey. Additionally,
I will talk about the development of the Metal-THINGS survey, which is observing nearby galaxies with Integral Field Spectroscopy. Metal-THINGS is currently collecting IFU data from VIRUS-P at the 2.1m Telescope at McDonald Observatory, Texas, and ESO-MUSE. The science goals will be presented, and any feedback will be appreciated.
