Please post links to the arXiv abstract pages, everyone: we don't always want to download a PDF just to read the abstract!
https://arxiv.org/abs/1712.07962
Edit to add: the abstract pages also often contain useful extra information, such as (in this case) a link to YouTube videos of the simulations -- https://www.youtube.com/channel/UC8ltFtaETXDphec0l-VxMsg -- or the publication history (in this case, a DOI is given).
