From fraser@m.universetoday.com on Mastodon: In 1987, the closest supernova in modern times flashed in our skies. Even though it was in the Large Magellanic Cloud, 168,000 light-years from Earth, astronomers detected the light and neutrinos from the supernova 1987A. It would be decades before the first gravitational wave observatory would come online. Astronomers have searched through gravitational wave data to see if there's a continuous signal coming from the supernova remnant, a rapidly spinning neutron star. http:// arxiv.org/abs/2310.19964
