On the orbital velocity of isolated galaxy pairs: a test of gravity in the low acceleration regime
The dynamics of isolated galaxy pairs represents an important tool to investigate the behaviour of gravity in the low acceleration regime. Statistical analysis of a large sample of galaxy pairs led to the noticeable discovery of a region of preferred 3-dimensional velocities centered at ~150 and ~100 km s -1 wide, a feature hard to justify in the
