About U1.11 large quasar group

The light we see from it set out 8.36 billion years ago, when the universe was 5.43 billion years old (redshift 1.11).

The map lists it as a large-scale structure and shows it at the scale of the large-scale universe, drawn on the supergalactic plane.

Its distance or nature is debated, and the map shows one published value.
