I did my job. And then I did a job that never should have been my responsibility afterwards, sending emails and having meetings about how this was allowed to happen in the first place. Other women scholars had to spend their time explaining to Aspen leadership why this was not ok.

“This record-breaking response reflects Webb’s exceptional performance and unprecedented capacity to inspire the scientific community and to transform our understanding of the universe,” said STScI Director Jen Lotz. 🔭 ☄️

Took a break from wrangling NSF grant application spreadsheets and instead decided to wrangle MLB team sentiment spreadsheets...

Trump "has expressed such outrage at attacks on Christians in Nigeria that he has threatened military intervention there... but here’s the awkwardness: Trump’s aid cuts are killing far more Nigerian Christians than Islamic terrorists are." @nickkristof.bsky.social www.nytimes.com/2025/11/08/o...

No opinion about this specific claim, but I do think we need more humanities in our lives and hearts and minds. And more arts. More history, more literature, more painting, more moral philosophy, more poetry. More thinking about and cherishing what makes human life special.

Dutch journalist/ historian @rutgerbregman.com at the World Economic Forum in Davos 2019, calling out the elites about the elephant in the room- "We've got to be talking about taxes!!" #inequality #taxes @taxwarroom.bsky.social @fairshareamerica.bsky.social @patrioticmillionaires.org

Stunning! 🤩

Hoping this helps our colleagues across the industry

Awesome new paper on galaxy evolution for the #astrosci crowd!

I have no faith that the DNC will have any idea how to proceed from here. But let's forget that for now -- congratulations Mayor Mamdani, Governor Sherrill, and Governor Spanberger!

Looking At NJ governor election results and... What is going on with Gen Z.

Still thinking about the group of kids who saw us trick or treating and said, "I think he's an Saja Boy"

What a nice relaxing game of baseball

Obscure question for #Ravens fans and journalists: I have this T-shirt that references "Splash '98 Funky Jungle" presented by the Baltimore Ravens. What event was this? Google search, ChatGPT turned up nothing...

TLDR; The PSF has made the decision to put our community and our shared diversity, equity, and inclusion values ahead of seeking $1.5M in new revenue. Please read and share. pyfound.blogspot.com/2025/10/NSF-... 🧵

Huge fan of Dr. Katie Mack, and much love for all she does for physics & astronomy + outreach. With that said, this statement is incomplete and misleading. A thread... > Chatbots — LLMs — do not know facts True! They don't "know" anything.

Fisher meets Feynman! 🤝 We use score matching and a trick from quantum field theory to make a product-of-experts family both expressive and efficient for variational inference. To appear as a spotlight @ NeurIPS 2025. #NeurIPS2025 (link below)

"I love all the exotic vegetables in Asian grocery stores."

People are always like "wow these Chinese veggies are so good what did you put in it?" Listen. It's just oil, garlic, and salt. You stir fry it. You can do it with cabbage. You can do it with broccoli. You can do it with spinach. You can do it with eggplant. You can do it. I believe in you.

First Light for 4MOST - what an experience! Paranal Observatory is already a magic place on its own right - but getting a new facility on sky ... that's hard to top! www.aip.de/en/news/4mos...

I love writing emails on my phone. Best regards, Kohn

Me: *travel for conference, give two talks, return home following week and pull all-nighters for JWST proposal on totally new topic, pull more late nights writing paper from scratch for ML conference paper due following Monday, and providing editorial comments on review article due Wednesday,

In college, deadlines are the enemy, because all problem sets are solvable. But in the real world, deadlines are your best friend, because real world problems can always be optimized further.

Cosmologists! We have a faculty job going here in Oxford - happy to answer questions. Brief version is that this remains a great & collaborative place to do science and the students are superb. 🔭 www.jobs.ac.uk/job/DOP628/a...

Catch us in Montreal!

Here is a genuine one :) CosmicAI’s AstroVisBench, to appear at #NeurIPS bsky.app/profile/nsfs...

I've never shuddered so hard at reading AI slop. Please make it stop arxiv.org/abs/2510.00063

Fantastic work on the size–mass relation for low-mass galaxies, led by Yasmeen (@yasmeenasali.bsky.social)! arxiv.org/abs/2509.25335 🔭🌌🧪

Any mutuals going to be in Montréal next week? Give me a shout if so! I'll be attending COLM and visiting UdeM, Ciela, and Mila, and presenting on various topics spanning ML applications in galaxy evolution to interpretable AI for scientific discovery.

Anyone else going to COLM? Give me a shout! Also, check out our poster on evaluating LLMs for astronomy research. This work came out of our 2024 JSALT research and was jointly led by undergrads Alina Hyk and Kiera McCormick!

Thanks Baltimore DOT for penalizing 40+ mph speeders more harshly, but by that point shouldn't you be revoking their driving license?
