Sorry folks I have another cat but she’s named Phoebe bc none of the other Galilean moons seemed right for her.
Phoebe was the first moon discovered via astrophotography, and was such a scardey cat when we got her we only caught her on cam. So for 2 weeks we only had photographic proof we had a cat

My paper (the one discussed below) has been accepted to the Astrophysical Journal!!!
I mean, no doubt that it would be, but it's always a good feeling. 😎 We'll aim for a press release once it's officially published because this is just such a darn interesting object...

New paper day!!!
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! 🧵

Continued Rapid Radio Brightening of the Tidal Disruption Event AT2018hyz
We present ongoing radio observations of the tidal disruption event (TDE) AT2018hyz, which was first detected in the radio at 972 days after disruption, following multiple non-detections from earlier ...

True story: Krauss was banned from CWRU campus for multiple sexual harassment episodes, including against me. You know it's bad when the dean himself confirmed it to the expose writers.
Krauss also held a physics conference on Epstein's island when I was in undergrad that included Stephen Hawking.

Avi Loeb really is the Dr. Oz of astronomy now. Impressive CV but full of pseudoscience so no one in the field likes him any more. 🔭

Trump just continually shooting our country in the face. This unwarranted (and likely illegal) destruction of Goddard is madness. It jeopardizes the next several decades of space exploration.
Reposting to correct an error: trump admin is quietly gutting 13 buildings and about 100 laboratories at Goddard campus that has been instrumental to Hubble and James Webb telescope missions. Staff say they’ve be locked and told to move equipment. Anything left behind will be thrown away.

This is IMO one of the biggest discoveries of the year, but you haven’t heard about it bc of a NASA press release/embargo stuck bc of the shutdown. I however have no such constraint (we’re tracking it in radio but haven’t finished the paper) so got to write about it! 🔭🧪
