Meanwhile, back in the world of research, I see that Maynooth University has issued a news item about a new paper by colleagues in the Department of Physics, Daxal H. Mehta, John A. Regan and Lewis Prole. The story has also been picked up by the Irish media, e.g. here. You may find the paper behind a paywall, as it is published in Nature Astronomy, so here is the abstract: And here's a pretty picture from one of the simulations used in the paper:
