Behold! Rare Quasar Triplet Forms Most Massive Object in Universe
Supercomputer simulations on Frontera reveal the origins of ultra-massive black holes, the most massive objects thought to exist in the entire universe. Shown here is the quasar triplet system centered around the most massive quasar (BH1) and its host galaxy environment on the Astrid simulation. The red and yellow lines mark the trajectories of the other two quasars (BH2 and BH3) in the reference frame of BH1, as they spiral into each other and merge.
