The polarized light spectra for the type 2 objects showed exactly the black-hole-related components seen previously only in the type 1 objects. ...we knew for certain that the type 2 objects possess the components relating to black holes, and that those components would be seen directly only along the axis of the active galactic nucleus. ...if astronomers are distributed randomly in the Universe, around half of them must classify our type 2 objects as type 1! ...similar data at slightly shorter wavelengths were previously presented by another group, who failed to identify the nuclear infrared source9.
