On 15th October at 10:00 am CEST, our IAU H1 club will hold a seminar focused on topics related to the Local Universe and ELT-SHARP plan. Our discussions are generally scheduled for the second Wednesday of each month at either ~10:00 am or 3:00 pm CEST, with some flexibility as needed. See you soon.
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...

Dark Matter or Modified Gravity? A virtual panel discussion
This is a quick post to announce that on Monday, April 7 there will be a virtual panel discussion about dark matter and MOND involving Scott Dodelson and myself. It will be moderated by Orin Harris…

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!

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…
