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.
Not 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.
Cold 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.
The DESIRED strong-line calibrations: I. New empirical metallicity relations for the local and high-redshift universe
This paper introduces the DESIRED strong-line metallicity calibrations, the most comprehensive empirical set for local and high-redshift galaxies.
The 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.
