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! 🧵

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.
“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”

It's a dark time for artists. Many are struggling!

It's easy to buy gifts online. When you buy from *artists*, you're supporting working people, instead of making rich jerks richer.

This fall, send your present $$ to an artist's shop!

Astronomy’s first gap-clearing planet fills in our “missing link”

We've seen protoplanetary disks with gaps, and fully mature systems with directly imaged planets.

For the first time, we've found them together: a disk-gap with an exoplanet inside.
