Gas-Phase Oxygen Gradients in Strongly Interacting Galaxies: I. Early-Stage Interactions

David S. N. Rupke, Lisa J. Kewley, L. -H. Chien

A consensus is emerging that interacting galaxies show depressed nuclear gas metallicities compared to isolated star-forming galaxies. Simulations suggest that this nuclear underab…

The Host Galaxies of Gamma-Ray Bursts II: A Mass-Metallicity Relation for Long-Duration Gamma-Ray Burst Host Galaxies

Emily M. Levesque, Lisa J. Kewley, Edo Berger +1

We present a statistically robust mass-metallicity (M-Z) relation for long-duration gamma-ray burst (LGRB) host galaxies at z < 1. By comparing the LGRB host M-Z relation to sample…
