July's IAU-H1 Colloquium was truly impressive and insightful.
Please note that the first two slides — the title and outline — are missing from the recording, but this does not affect the scientific content or your overall enjoyment. Thank James.

Things I don’t understand in modified dynamics (it’s cosmology) I’ve been busy, and a bit exhausted, since the long series of posts on structure formation in the early universe. The thing I like about MOND is that it helps me understand – and succes…

Their figure 6, showing their final membership. You can see cool details in GD-1 (like the spur in the middle of the left panels.)

Paper of the day #2 for me is by Kiyan Tavangar and @adrian.pw, who made a really nice way to model the structure of stellar streams, demonstrated on GD-1. #milkyway

The membership that they get out looks really good! arxiv.org/abs/2502.13236
