The AURORA Survey: Determining the Production Mechanism for OI $\mathbf{\lambda 8449}$ Emission in Star-forming Galaxies at Cosmic Noon

We analyze deep JWST/NIRSpec observations of 58 star-forming galaxies at $1.3<z<4.8$ in the AURORA survey to investigate the origin of the permitted OI $\lambda 8449$ emission feature. Based on the detection of OI $\lambda 8449$ in a stack of objects with non-detections, we infer that this feature is ubiquitous among s...

MEGATRON: Dwarf Galaxy Quenching in the Epoch of Reionization

Low-mass galaxies during the Epoch of Reionization are expected to form stars in short bursts separated by periods of inactivity, but what regulates this cycle, and how sensitive it is to the modelling of stellar feedback, remains unclear. We use the MEGATRON high-redshift zoom simulation suite, in which four star-form...
