Currently reading the Project Hail Mary book and there’s a ton of astrophysics in it—no spoilers but early on there’s infrared spectroscopy, ALMA, and more. Curious to hear what other astronomers think!

Well said

Neat work on precision PSF modeling of Gaia! Little known fact: we captured Kepler driftscan PSFs during downtime in the K2 mission. PSF modeling is great boon for low SNR science, extended objects, etc.

Good band name, or maybe a softball team composed in part by punk rock astronomers with a fastball

It’s me

Sans serif math in LaTeX is so satisfying. \mathsf{}

Very cool opportunity to make differentiable physics models for EPRV, work with Ben and co, and live in a cool place. Pretty much a dream job, apply!

Still want a JAX for science conference, where all my JAX scientists at

The sheer joy I felt just now discovering that there is a new Dan Foreman Mackey video about JAX.

standing room only for physics? faith in humanity restored ✨👏

I still feel like differentiable models are under appreciated, it’s like a magic super power for interpretability and extensibility. Maybe LLM-assisted coding can bring autodiff to more science teams? Still a mental leap to adoption.

Everything becomes so much easier when you can forward model your data

Looking back on this talk about autodiffable spectral models, there is still so much promise, I’d love to see what folks have been up to in this space! speakerdeck.com/gully/blase-...

New job opportunity at @stsci.edu: Senior Astronomical Data Scientist for data analysis tools, working closely with my team and me. This role is very similar to mine. If you have questions, I'm happy to answer them. 🧪🔭

Currently 83% carbon-free energy in Texas right now: - 40% wind - 33% solar - 10% nuclear Wholesale prices are negative, and 3.5 GW of batteries are charging. ☀️💨⚛️🌎

Despite headwinds, over 20 new EVs are coming to the US market in 2026, including several more affordable vehicles. Can any thrive without federal tax credits? insideevs.com/news/782572/... 🔌💡 🔌🚗

It’s wild that stellar limb effects start to matter at non-negligible fractions of a resolution element on the ELTs! Challenge… or opportunity!?

The first batteries rolled off the production line at Toyota’s new $14 billion battery plant in Liberty, North Carolina. The plant will produce batteries for hybrid, plug-in hybrid & electric models, which Toyota plans to make up 70% of its sales by 2030 electrek.co/2025/11/17/t... 🔌💡 🔌🚗

Get outside into a dark place if you can tonight - no guarantees, but a possible brilliant display of the northern lights.

Hat tip @wilsonar.bsky.social for this! 🤣

"Nearly all important discoveries pass through a stage of neglect or obscurity,” Professor W. Grylls Adams went on to explain. “Either the public attention is already preoccupied, or the discoveries come at a time when the public are not prepared to receive them". Energy, Rhodes

Bookmarking to read later. Several great-looking papers already on the back log! Bravo to folks doing the hard work

you cannot do inference without making assumptions 💜 David MacKay inference book still free PDF www.inference.org.uk/mackay/itila...

Just made some sick animations, very jazzed so share these more widely someday

Howdy yall, how’s it going? Good here 👋

Thrilled to have two years' of work out, in a pair of papers led by @gradientrider.bsky.social and @maxecharles.bsky.social. We've built a data-driven calibration of the James Webb Interferometer to near its fundamental limits for high-res imaging - explainer at @aunz.theconversation.com!

The figures in this paper are so satisfying!

Gotta say I am enjoying GitHub copilot PRs and code reviews. It really feels like a healthy balance of human in the loop guardrails and leveraging LLMs strengths.

Academic tautology

Brown dwarf research (!) was used as the example of how AI slop pollutes internet references youtu.be/_zfN9wnPvU0?...

Pre-LLM human-authored content is like pre-WWII steel, a precious and now scarce resource en.wikipedia.org/wiki/Low-bac...

And as a bonus, here's a false-color composite of the same. Blue is mapped to all of visible, green is infrared beyond 850nm, and red is the methane band at 889nm. 🔭 #astrophotography #saturn

Yall check this out, it’s the top coolest thing I’ve seen in a while, closed form autodiffable representation of optical interferometry, enormously powerful. Yes!!

So stoked about this!

This rules

Is anyone using Typst? Thoughts?

Ooo new iTerm dock icon is satisfying

Interesting exchange between @jigarshahdc.bsky.social and @stephenlacey.bsky.social on latest Open Circuit episode w/ @charlesxhua.bsky.social 🔌💡 www.latitudemedia.com/news/open-ci...

Paper submitted! Quite proud of this one, the plots are pretty 🔭

Thinking of giving my GitHub Issues clickbait titles

What’s cool and new in astronomy these days? That imaged planet in the disk is sick.

It’s still so bizarre to me that there’s no unified Slack login, have to manually sign in to possibly a dozen or more Slacks.

When you merge 10 PRs in a row and your contribution graph goes brrrr 🟩 🟩 🟩 GitHub Breakout by Cyprien Guillemot is a GitHub Action that turns your commits into a Breakout-style SVG, updates daily, and swaps for light/dark mode 🤯 #ForTheLoveOfCode https://github.com/cyprieng/github-breakout

Astral (the VC-backed company behind the popular open source Python tools uv, ruff and ty) have unveiled the first hints at their business model today - pyx, a private package registry for companies that use Python My notes here: simonwillison.net/2025/Aug/13/...

Images from Palomar at 2 different infrared wavelengths last night - one that Saturn's methane atmosphere absorbs, and one the it reflects! (The faint point source is the moon, Tethys!) Taken by David Ciardi, Catherine Clark, @lowbacca.bsky.social and Miranda Felsmann; animated by me (and ezgif!)

Interesting to revisit Mamajek's Law from 2016 - that the number of known exoplanets is increasing exponentially - in light of new data. Extrapolating this discovery rate to 2025 we should have found nearly 47k planets (!) vs actual: 5967 Gaia save us!

🤯

blasé in the wild! Also nice violin plots!

It’s a Texas thing

I just participated in a nice career panel for the Northwestern CIERA REU program. It was fun! Some of my points: - the world will need more people working on decarbonization - Astro problem solving is well suited to many climate tech roles - Start a startup!
