Observations of the Gas Reservoir around a Star Forming Galaxy in the Early Universe


We present a high signal-to-noise spectrum of a bright galaxy at z = 4.9 in 14 h of integration on VLT FORS2. This galaxy is extremely bright, i850 = 23.10 ± 0.01, and is strongly-lensed by the foreground massive galaxy cluster Abell 1689 (z = 0.18). Stellar continuum is seen longward of the Lyα emission line at ∼ 7100 Å, while intergalactic H I produces… (More)
