The Sins Survey: Broad Emission Lines in High-redshift Star-forming Galaxies

Abstract

High signal-to-noise, representative spectra of star-forming galaxies at z ∼ 2, obtained via stacking, reveal a high-velocity component underneath the narrow Hα and [NII] emission lines. When modeled as a single Gaussian, this broad component has FWHM & 1500 km s; when modeled as broad wings on the Hα and [NII] features, it has FWHM & 500 km s. This feature… (More)
