interesting discussion.
Paper day! My PhD student Mariana Júlio, with @readdark.bsky.social, @pengfeili.bsky.social and others, studies the internal dynamics of dwarf galaxies and finds they don't agree with the Radial Acceleration Relation, challenging the dark matter alternative MOND.

The radial acceleration relation at the EDGE of galaxy formation: testing its universality in low-mass dwarf galaxies
A tight correlation between the baryonic and observed acceleration of galaxies has been reported over a wide range of mass ($10^8 < M_{\rm bar}/{\rm M}_\odot < 10^{11}$) - the Radial Acceleration Rela...

In the month+ since Jeff Bezos announced the WaPo editorial page would be advocating for “personal liberties and free markets,” there have been troubling resignations, at least one (Ann Telnaes) b/c of being silenced. But as of today, no real signs of substantive change.

interesting for YOC field
An interesting #galactic paper by Cameren Swiggum (@mac0598.bsky.social) et al. came out today! ☄️🧪
Extending previous work that showed most young star clusters near to the Sun came from just three regions, Cameren shows that actually *all* nearby clusters come from just three regions!
