Jacqueline Hodge (Leiden Observatory), "A dust-unbiased view of high-redshift star formation"
A substantial fraction of the Universe's star formation is heavily enshrouded by dust, and this basic fact has long been a hindrance to the development of a complete picture of galaxy evolution. Now, thanks to the advent of the Atacama Large Millimeter Array (ALMA) and the upgrades to the Karl G. Jansky Very Large Array (VLA), our view of dusty star formation at high-redshift is undergoing a radical transformation. I will present recent ALMA and JVLA observations of the gas, dust, and dust-unbiased star formation in high-redshift galaxies down to ~kpc and even sub-kpc scales, providing key insight into the morphology, dynamics, dark matter halo masses, and interstellar medium conditions in these systems. These observations have important implications for our understanding of the formation of the dustiest galaxies in the universe and the overall star formation rate history of the Universe.
