A quasar pair at z=5.7 is confirmed in a galaxy merger via ALMA, setting a lower limit of >1.2% on the pair fraction at 5.5<z<6 and linking it to the PTA gravitational wave background.

Synthetic proximity-zone spectra plus a simple peak-finding algorithm can distinguish line-of-sight separations of quasar pairs at the 0.2–0.5 pMpc level for sky separations of 10–100 pkpc and still separate close versus distant pairs at 1 pMpc sky separation.

A Close Quasar Pair in a Massive Galaxy Merger at $z=5.7$
A quasar pair at z=5.7 is confirmed in a galaxy merger via ALMA, setting a lower limit of >1.2% on the pair fraction at 5.5<z<6 and linking it to the PTA gravitational wave background.

The Quasar Proximity Effect as an Alternative Probe of Quasar Pair Distances
Synthetic proximity-zone spectra plus a simple peak-finding algorithm can distinguish line-of-sight separations of quasar pairs at the 0.2–0.5 pMpc level for sky separations of 10–100 pkpc and still separate close versus distant pairs at 1 pMpc sky separation.
