Witnessing the Earliest Phases of Galactic Wind Formation in Superluminous Supernova Hosts: Implications for Star-formation-driven Outflows in Low- and High-redshift Galaxies

A. Saldana-Lopez, A. Gkini, M. J. Hayes +6

Direct observational constraints on the earliest phases of galactic outflows remain scarce. We present Very Large Telescope/X-shooter spectroscopy of seven Type I superluminous sup…
