could this quasar be unique/ not normal.?
Most super massive black hole to date aren't even 1/3 that size.

There are two reasons why the most distant quasars have the most energy output:
1) The highest output quasars are extremely rare. Therefore to find any significant numbers you have to look further into space, simply because volume examined is proportional to the cube of the radius.
For example if you only look out ten light years you would be inspecting about 3000 cubic light years. But if you look out twenty light years you are inspecting 24000 cubic light years. Clearly the further out you look the greater the volume of space examined and hence the greater the chance of finding unusual objects.
2) Only the highest output objects can be seen over the greatest distances. Obviously.
CHeers!

why do you call your mom a distant Quasar?
