Post-starburst galaxies show compact morphologies with minimal wavelength-dependent structural change and low overall disturbance levels, except for enhanced residual asymmetry in massive systems at z > 1, supporting two distinct quenching pathways.
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.
DESI DR2 identifies 50,088 galaxies with moderate and 27,420 with strong evidence for down-the-barrel NaI D absorption revealing inflows at ~20 km/s and multiple accretion pathways at z < 0.6.

The multiwavelength structure of post-starburst galaxies at 0.5 < z < 3 with JWST PRIMER: compact morphologies and residual disturbances
Post-starburst galaxies show compact morphologies with minimal wavelength-dependent structural change and low overall disturbance levels, except for enhanced residual asymmetry in massive systems at z > 1, supporting two distinct quenching pathways.

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.
