Effective Opacity of the Intergalactic Medium from Galaxy Spectra Analysis

Jose S. Monzon, J. Xavier Prochaska, Khee-Gan Lee +1

We measure the effective opacity (${\tau }_{eff}$) of the Intergalactic Medium (IGM) from the composite spectra of 281 Lyman-Break Galaxies (LBGs) in the redshift range $2 \lesssim z \le…
