n Very few high-luminosity Type II quasars are known.<br />
Essentially all high-luminosity objects show broad<br />
lines.<br />
n If the unification model is correct, then Type II<br />
quasars must exist at high luminosity.<br />
Characteristics:<br />
n Characteristics:<br />
n Weak or absent non-thermal continuum<br />
n Strong narrow high-ionization emission lines<br />
n So we went to look for such objects in SDSS!<br />
