arxiv paper: <a href="https://arxiv.org/abs/2504.16872" rel="nofollow">https://arxiv.org/abs/2504.16872</a>.<p>I was fortunate enough to attend a dinner where Joe Taylor, whose Nobel Prize involved long-term study of pulsar intervals decay. He brought along a recording of several pulsars, ranging from multi-second intervals down to one whose rotational speed was 600/second.<p>(Joe Taylor is also the author of WSJTX, a weak-signal radio protcol.)
