... The picture shows a 2-dimensional sketch of the outflowing wind of a quasar (Elvis 2000, Astrophysical Journal , vol.545, p.63-76). In the funnel-shaped disk wind Elvis (2000) model a wind arises from a restricted range of radii on the accretion disk around the central black hole. Initially the wind makes a large angle to the disk plane (and so is roughly cylindrical). ... Looking through the quasi-cylindrical part of the wind we see UV and X-ray warm absorbers. ...
