Delayed Feedback in High-$z$ Starbursts Revealed by Lyman-$\hat{I}\pm$ Profiles and Metal Line Diagnostics

James Nianias, Jeremy Lim, Yik Lok Wong +1

Lyman-$\hat{I}\pm$ emission, which owing to its resonant nature strongly couples the emergent line profile to gas kinematics, is a key observable for probing outflows from star-forming gal…
