How Steep is your Dust? Direct Measurements of Nebular Attenuation Curves at Cosmic Noon with JWST

Year: 2026

Type: preprint

Abstract: Tracing the shape of the nebular attenuation curve, which is crucial for accurately measuring intrinsic emission-line fluxes, has proven challenging both in the local universe and at high redshift. Here we present nebular dust attenuation curves measured directly for 24 star-forming galaxies ($9.3<\log(\rm M{\star}/M_\odot)<11.1$) at cosmic noon ($1.8
