SAMI Zoom: resolved recalibration of metallicity relations

Sarah Sweet (Swinburne University of Technology)

We are using tiny bundles of optical fibres to zoom in on nearby galaxies and see blobs of gas that are forming new stars. The 3D pictures of these blobs tell us how the temperature and chemical content vary inside them. This enhanced understanding allows us calibrate the same measurements for distant galaxies, which are too far away to zoom in on but still just as interesting.
