William Thompson I'm a big fan of Julia programming!

Wishing everyone a happy and healthy arXiv2501 . . . 😉🪩🎉 So thankful for everyone around the world who uses arXiv to share and discover new research. Here's to more #openscience in the new year! #happynewyear #newyearnewscience #2025

whole article is incredible and has 5-6 “koans” about git’s (horrible) quirks

Silver lining of being in unexpectedly Ottawa this week instead of at #AAS245 is the shawarma

Though many events in space take place over vast timescales, these rings (Webb spotted 17 of them) are moving outward from their stars at more than 1600 miles/s, making them noticeably different from one year to the next. This animation shows changes in WR140 between 2022-2023.

One photo with: Milkyway, Zodical light, Starlink satellites as streaks, stars as pin points, atmosphere on edge showing OH emission as burned umber (my favorite Crayon color), soon to rise sun, and cities at night as streaks. Taken two days ago from Dragon Crew 9 vehicle port

The heretical thought occurs to me as I dig into “The Stars, Like Dust” that I do not in fact enjoy Isaac Asimov’s long form writing.

Law of controls: write C code for real-time embedded hardware. You can't use #python or #rstats etc. for that, right? With #julialang v1.12, we demonstrate it's possible to ahead of time compile to small binaries for use in controls applications. #sciml arxiv.org/abs/2502.01128

Load in 4k to spot the ISS

Just saw someone saying using the em-dash is a sign of something being written by AI, because real people rarely use it. This is terrible news for everyone like me who has an unhealthy emotional attachment to the em-dash.

Researchers from UVic’s Astronomy Research Centre used the James Webb Space Telescope to captured a rare glimpse of how young planets are forming. This groundbreaking discovery reveals how planets compete with their host star for material shorturl.at/Ei7Fh ARC-UVic #JWST

The Flag That Unites Us. Happy #FlagDay! 🇨🇦

Taking my glasses off when I get home after a long day because I’ve seen enough

Our paper on a differentiable spectral model, ExoJAX2, has been accepted by ApJ. In this paper, we use HMC-NUTS to analyze JWST’s native-resolution transmission, high-dispersion spectra of a brown dwarf from Subaru, and Jupiter’s reflected light. arxiv.org/abs/2410.06900 1/N

A surprising & little-known results in classical statistics: Mean (μ) and median (m) are within one std deviation: |μ−m| ≤ σ For unimodal densities, bound is even tighter |μ−m| ≤ 0.7746 σ This beautiful results first appeared in a 1932 paper by Hotelling & Solomons 1/3

New paper! In work led by Sabina Sagynbayeva we quantify mission and ancillary data (RV, astrometry) requirements that enable "full system" (terrestrial AND giant planets) characterization with the Habitable Worlds Observatory. arxiv.org/abs/2507.21443

Great work by Sabina and co-authors! Plus lots of nice showcases of Octofitter and PairPlots :)
