High-Redshift Metals. II. Probing Reionization Galaxies with Low-Ionization Absorption Lines at Redshift Six
George D. Becker, Wallace L. W. Sargent, Michael Rauch +1
We present a survey for low-ionization metal absorption line systems towards 17 QSOs at redshifts z_em=5.8-6.4. Nine of our objects were observed at high resolution with either Kec…

Measurements of the UV background at 4.6 < z < 6.4 using the quasar proximity effect
Alexander P. Calverley, George D. Becker, Martin G. Haehnelt +1
We present measurements of the ionising ultraviolet background (UVB) at z ~ 5-6 using the quasar proximity effect. The fifteen quasars in our sample cover the range 4.6 < z_q < 6.4…
