On the orbital velocity of isolated galaxy pairs: II accurate MOND predictions

ABSTRACT Examining a catalogue of isolated galaxy pairs, preferred orbital intervelocity ? 150 km s?1 was recently reported. This discovery is difficult to reconcile with the expectations from Newtonian numerical simulations cosmological structure formations. In previous paper, we have shown that for pairs expected in Modified Dynamics (MOND). Here detailed analysis MOND predictions presented, showing remarkable agreement observations can be achieved mass-to-light ratio M/L?1 solar units. agrees typical stellar population, without requiring non-baryonic dark matter these systems.
