Bonus: here's an animation I generated showing how the sausage was made. Each frame is one commit from the paper repo.

I was Leo before this Pope

Something my SXS colleagues and I have been working on for the past six years: https://arxiv.org/abs/2505.13378

The SXS Collaboration's third catalog of binary black hole simulations
Scheel et al.

We have a little news blurb here: https://www.black-holes.org/2025/05/19/catalog-update

Here's a nice figure — read the news blurb for a short explainer, or the paper for more details!

I learned yesterday that I am a 2025 Kavli Fellow!

Wake up babe, new preprint just dropped

Length dependence of waveform mismatch:
a caveat on waveform accuracy
Mitman, Stein, et al.
https://arxiv.org/abs/2502.14025

Maintaining open-source software that others rely on actually takes time!!!

I updated my notes on the magnetostatic multipole expansion at https://duetosymmetry.com/notes/magnetostatics-stf-mpoles/ — mainly because Cyril Pitrou found an error (1/2 should have been ℓ/(ℓ+1)), and pointed me to Damour+Iyer (1991). Sorry for having wrong notes up for so long!

Nice: my CV just hit 69 publications

🎉 arXiv submission day! 🎉

Making N64 Zelda relativistically correct and calling it Ocarina of Spacetime

🎉 Paper acceptance day! 🎉

Y'all it's a 🎉 New paper day 🎉 for me, and I wrote an explainer over on bluesky... I don't have the energy to copy it over here. Too many platforms! Check out my explainer at https://bsky.app/profile/duetosymmetry.com/post/3ld2p73zkzs2o or just read the paper at https://arxiv.org/abs/2412.06887.

Last night I was feeling like a grad student as I was deriving the coefficients l/(l+1) and (2l-1)/(2l+1) in this formula (from Blanchet+Damour 1986):

Any emacs / font experts want to chime in? https://emacs.stackexchange.com/questions/85043/how-does-font-substitution-work-for-unicode-combining-characters

Do I know anybody who knows Harish-Chandra stuff? Or anybody I don't know who wants to explain some of these things to me?

Chemists/biologists/other folks who use preprint servers besides the arXiv: Do you get bibtex entries with the eprint=... field pointing to servers different from the arXiv?
