A Metal-poor Damped Ly α System at Redshift 6.4 by Bañados, Eduardo, Rauch, Michael, Decarli, Roberto, Farina, Emanuele P, Hennawi, Joseph F, Mazzucchelli, Chiara, Venemans, Bram P, Walter, Fabian, Simcoe, Robert A, Prochaska, J Xavier, Cooper, Thomas, Davies, Frederick B, Chen, Shi-Fan S

“…However, in order to match the data a contribution of an intergalactic medium 5%-38% neutral or additional weaker absorbers near the quasar is also required. …”

An 800-million-solar-mass black hole in a significantly neutral Universe at a redshift of 7.5 by Bañados, Eduardo, Venemans, Bram P, Mazzucchelli, Chiara, Farina, Emanuele P, Walter, Fabian, Wang, Feige, Decarli, Roberto, Stern, Daniel, Fan, Xiaohui, Davies, Frederick B, Hennawi, Joseph F, Simcoe, Robert A, Turner, Monica L, Rix, Hans-Walter, Yang, Jinyi, Kelson, Daniel D, Rudie, Gwen C, Winters, Jan Martin

“…We see strong evidence of absorption of the spectrum of the quasar redwards of the Lyman α emission line (the Gunn-Peterson damping wing), as would be expected if a significant amount (more than 10 per cent) of the hydrogen in the intergalactic medium surrounding J1342 + 0928 is neutral. …”
