HETDEX Public Source Catalog 1—Stacking 50,000 Lyman Alpha Emitters <sup>∗</sup>
Abstract We describe the ensemble properties of the 1.9 < z < 3.5 Lyman alpha emitters (LAEs) found in the HETDEX survey’s first public data release, HETDEX Public Source Catalog 1. Stacking the low-resolution ( R ∼ 800) spectra greatly increases the signal-to-noise ratio (S/N), revealing spectral features otherwise hidden …
