Spatially resolved observations of z~0.1 galaxies show Mg II absorption outflow velocities are systematically higher than Hα emission velocities by ~0.4 dex while maintaining similar correlations with star formation rate and surface density.
Synthetic stellar population models show TRGB luminosity varies by at most 0.028 mag from typical changes in alpha enhancement, age, and helium at fixed metallicity, confirming its robustness as a distance indicator.

Differences between emission and absorption tracers of spatially resolved outflows in clumpy z ~ 0.1 star-forming galaxies
Spatially resolved observations of z~0.1 galaxies show Mg II absorption outflow velocities are systematically higher than Hα emission velocities by ~0.4 dex while maintaining similar correlations with star formation rate and surface density.
