Shape of Direct-Method Mass-Metallicity Relation with JWST: Fast-Track Nitrogen and Helium Enrichment
JWST data reveals the mass-metallicity relation from z=1-9, showing how auroral-line selection and star-formation history shape early galaxy enrichment.

Galaxies & CosmologyNot So Isolated: Green Pea Galaxies in Overdense Environments revealed by VLT/MUSE
Green Pea galaxies are found in overdense environments with companions, suggesting their starbursts are driven by gas accretion rather than close mergers.

Galaxies & CosmologyCold molecular gas distribution and kinematics in the low-metallicity dusty starburst of Mrk 996 resolved with ALMA
ALMA observations of Mrk 996 reveal compact, dynamically perturbed cold molecular gas clouds, weakly coupled to stellar feedback in a low-metallicity starburst.

Galaxies & CosmologyThe k-MENDEL sample of local analogs to reionization galaxies. Spectral identification of EELGs and properties of green peas in DESI
DESI identifies ~16,000 extreme emission-line galaxies (EELGs) as local analogs to reionization-era galaxies, characterizing their properties.
