Abstract

*Abstract*

Throughout the history of the universe, shocks and large-scale gas flows have moulded the arms of spiral galaxies, formed the bulges of the most massive galaxies in the universe, fed supermassive black holes in the centres of galaxies, fuelled generation upon generation of new stars, and enriched the intergalactic medium with metals. I will present the latest results from our large local 3D survey to understand the relationship between galactic-scale outflows, star-formation, and active galactic nuclei in galaxies as a function of environment and redshift. For local galaxies, we use multi-object integral field spectroscopy to build the largest sample of galaxies with wide 3-dimensional imaging spectroscopy. We probe the early universe by combining gravitational lensing with new infrared 3-dimensional imaging spectroscopic technology. Gravitational lensing allows us to probe the fundamental processes occurring within actively forming galaxies just 4 billion years after the Big Bang. In this lecture, I will present the latest results of our large survey to track how the star formation, chemical abundances, and galactic-scale outflows changed within galaxies over the past 11 billion years.
