TL;DR- two years after shredding a star, a black hole called AT2018hyz (nickname: Jetty McJetface) began rapidly rising in radio emission- we think it's bc of an outflow w up to 10 TRILLION times the energy of the Death Star! Here's the latest! 🧵

Prohibited activities include advising Chinese graduate students. For reference, a recent Georgetown report estimated 16% of STEM graduate students in the US are Chinese nationals.
This would take out entire fields at the knees, which is perhaps the point.
