From the author on reddit

"Astronomer here! I am the lead author on this paper, which is definitely the discovery of a lifetime! The TL;DR is we discovered a bunch of material spewing out of a black hole’s surroundings two years after it shredded a star, going as fast as half the speed of light! While we have seen two black holes that “turned on” in radio 100+ days after shredding a star, this is the first time we have the details, and no one expected this!"
