Abstract

We show some significance against the null hypothesis of random interactions of binary spiral galaxies, and in favour of the alternative that more interactions than expected occur for axes either nearly parallel (spins being parallel or anti-parallel) or nearly orthogonal. We discuss this in the context of similar prior studies, using a different statistical focus in such a way that we are able to incorporate additional data.
