Measures a new nebular attenuation curve from 1400-9550 Å for galaxy GOODSN-17940 at z=4.41 that is steeper than Milky Way/SMC/Calzetti at long wavelengths, similar in blue-optical, and shallower in UV with no 2175 Å bump.

Nebular H-alpha attenuation is 0.20 dex higher than standard Balmer decrement plus Galactic curve methods, with nebular curves showing higher Rv than stellar curves due to porous dust from stellar feedback.
The ionization parameter inferred from O32 rises with redshift and sSFR, falls with stellar mass, and increases by ~4x from z=2 to z=6 at fixed mass and sSFR, with a ~0.3 dex model systematic.
The Sparks survey divides local galaxies into first-burst, second-burst, and post-burst groups, finding AGN predominantly in second-burst systems and implying a short delay before black hole accretion.
Simulations of SPHEREx line intensity maps show cross-correlations (e.g., Hα × [OIII] at z=5) can reach S/N up to 99, probing galaxies with M < 4×10^10 M⊙, though most signal comes from brighter directly detectable galaxies.

On Cross-Correlating Line Intensity Maps from SPHEREx during Reionization
Simulations of SPHEREx line intensity maps show cross-correlations (e.g., Hα × [OIII] at z=5) can reach S/N up to 99, probing galaxies with M < 4×10^10 M⊙, though most signal comes from brighter directly detectable galaxies.
