Also (I just posted a suggestion on accessing the SDSS data on the other thread), if you want to actually show that this ejection scenario is real, you need to perform a cross-correlation analysis on a very large sample of uniformly selected galaxies and quasars, like that in SDSS or 2dF. I'm not aware that anyone has actually done this, with proper controls for the quasar selection function.

Looking at individual galaxies is nice and all, but there are hojillions of galaxies out there, and you would expect plenty of chance alignments if you are not careful in how you select sources. The sampling should be uniform and random. You can't just find one (or even "many," as you claim Arp has) "aligned" system and claim it represents some new physics.
