Gas number density n (upper panels) and neutral fraction XH (lower panels) at two separate instances around t~4,000 yr. The left panels show the flow during a central accretion minimum; infalling gas is clearly visible at r~1.5 x 1016 cm. The right panels show the flow during a central accretion maximum. The structure near the central axis, in the conical region marked by dashed lines, is an artifact of our having set the optical depth to zero along the axis, for R/|z| < tan5°, to avoid numerical issues arising from the coordinate singularity.
