"Galaxy Evolution in 3D"


Tracing matter and chemical elements in the Universe is critical for understanding the formation of the first galaxies, the formation and growth of supermassive black holes, and ultimately the evolution of galaxies like our Milky Way. Throughout the history of the universe, 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 centers of galaxies, fueled generation upon generation of new stars, and enriched the intergalactic medium with metals. The physics and impact of these processes can now be traced through new efficient, wide-field 3D integral field spectrographs. With multi-object integral field spectroscopy, we can now probe these transformative galaxy processes statistically for thousands of galaxies. I will describe how our understanding of galaxy evolution has been changed through these surveys to help us understand the relationship between gas inflows, galactic-scale outflows, star-formation, chemical enrichment, and active galactic nuclei in galaxies. I will link these studies with new insights into the early universe traced through gravitational lensing and infrared adaptive optics. I will finish by discussing how this field will be transformed in the JWST and ELT era.
