Exploring Spatially-Resolved Metallicities, Dynamics and Outflows in Low-Mass Galaxies at
L. R. Ivey, J. Scholtz, A. L. Danhaive +18
A majority of JWST/NIRSpec/IFU studies at high redshifts to date have focused on UV-bright or massive objects, while our understanding of low-mass galaxies at early cosmic times re…

Only Nitrogen-Enhanced Galaxies Have Detectable UV Nitrogen Emission Lines at High Redshift
Peixin Zhu, Lisa J. Kewley, Tiger Yu-Yang Hsiao +1
The detections of bright UV nitrogen emission lines in some high-redshift galaxies suggest unexpectedly high nitrogen-to-oxygen ratios () compared to loca…
