Wave equations estimates and the nonlinear stability of slowly rotating Kerr black holes — mentioned by raattgift

That's an unexpectedly neat question. Gravitational radiation can form caustics, so in one way, yes. This was an area of theory that Bondi and Pirani were interested in during the 60s to 80s. Caustics are meant in the sense of the bright spots in https://en.wikipedia.org/wiki/Caustic_(optics) but rather than some "rogue wave" you might get a black hole. More recently mathematical-relativity studies of the stability of Kerr black holes included a 900+ page paper https://arxiv.org/abs/2205.14808 which among other things considers something like a rogue wave passing through a spinning black…

tl;dr: gravitational waves do hard-to-calculate things inside a strong ergoregion around a fast-spinning black hole, and may do hard-to-calculate things to the black hole, and those calculations are outside the scope of the paper. > [how to define] 'slowly rotating' [might be] pretty cool It's for a pretty cool reason. Bear in mind that I am not a superhuman so have not read the 900-page document rather than scanning through the most interesting bits. Also, forgive me, I got a bit lazy and have left in a bunch of redundancy below rather than trimming it out or reorganizing it. The question in…

Almost all arXiv submitters (and certainly any serious one in a category like this paper's math.AP (Mathematics / Analysis of Partial Differential Equations) <https://arxiv.org/list/math.AP/new>; click the "other" in "[pdf, ps, other]" and there click Download sources) will supply the preprint's sources, which in mathematics-heavy fields are almost always LaTeX. The sources are associated in a predictable way with the abstract page, which is what should practically always be supplied instead of a direct link to a PDF or other final format. In this particular case…

Pdfs are readable by machines. It's also released as tex. https://arxiv.org/format/2205.14808 Huh. this account apparently got shadowbanned. Guess it's another good reminder not to post here.
