Extended Data Fig. 4: Velocity structure of the redshifted Hα broad absorption line of J1035 + 1422.
From: Fast inflows as the adjacent fuel of supermassive black hole accretion disks in quasars
The optical depth (red) and local covering factor (blue) of the line, derived from the continuum-normalized spectrum, are shown as a function of velocity shift with respect to the quasar’s rest frame. The error bars represent 1σ uncertainties.
