Characterizing the ISM using Fine-Structure Lines in a z=5.7 Hyper-Starburst Galaxy Merger

SPT0346-52 is a gravitationally lensed dusty star-forming galaxy at z~5.7 from the South Pole Telescope sample1. It is an extremely luminous hyper-starburst system with intrinsic far-infrared luminosity > 10 13 Lsun and star formation rate density ~4200 Msunyr -1 kpc 2 . Based on ALMA observation...
