Astronomer here! I’m a Hungarian-American radio astronomer, alias /r/Andromeda321 on Reddit. Assistant professor at the University of Oregon
My first 200+ person class has been an exercise in student excuses, but today’s a new one- a request to miss the in person final from a student who’s not even enrolled in my class!
I mean yes, you can miss the final, but maybe not the answer you were really after here 😂

Just in time for the weekend- my rendition of Carl Sagan's Pale Blue Dot!
I have loved this since high school and knew if I was teaching a solar system class I had to do it. Not gonna lie, if this is the ONE thing my students remember from my class years later I'm happy 🔭🧪🎢

Just did my first look at applications for a postdoc position I advertised. I am BEGGING you- if you're applying for a postdoc, please actually say what you're interested in that my group does! Sooooo many submit an app that never says how they want to connect to what we do! 🔭🧪

Astronomers, question! If you have a dedicated astronomy major, what upper level *physics* classes do you require your students to take?
We are getting our Astro major together at Oregon, and while I think a class of classical+E&M, we’re wondering if a class in QM is actually useful 👀

In some ways the weirdest thing to me about the Epstein files vote is how a few months ago Pam Bondi officially said there was nothing in them. In normal times this would be a gigantic scandal in itself that the Attorney General lied… and now it’s just a Tuesday.

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! 🧵

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. 🔭
