Exciting news to share: Astropy has been awarded the 2025 Lancelot M Berkeley AAS Prize! (aas.org/press/astrop...) So if you'll be at the AAS this year be sure to stay to the end for the Prize talk by me and fellow Astropy Coordinators Kelle Cruz and Clara Brasseur.
E di Teodoro in #iaus392#astronomy2024@jegpeek.bsky.social) gives a really nice clean story of disentangling gas flow directions to show that at least radial gas flows aren't bringing in enough fuel to sustain star formation at the present day
Nice summary of some LADUMA results in talk by A Baker from #iaus392#astronomy2024@jwuphysics.bsky.social showing that you can pick out even individually undetected HI features using CNNs trained on multiwavelength data
From J Healy in #iaus392#astronomy2024 : in an HI survey of cluster Abell 2636 (with MeerKAT I *think*), some evidence that subgroups within the cluster protect galaxies' gas from the broader cluster environment. I wonder if this happens at LG scales (and if it could ever be observed...)?
So enjoying hearing about neutral hydrogen observations of the Milky Way from Snezna Stanimirovic this morning. #astronom2024 🔭👩🔬
Neat dataset by P Mancera Piña at #astronomy2024 of HI rotation curves of several UDGs, showing that while their dark matter halo concentrations are hard to explain in CDM (and even harder with MOND), they are much more likely to exist in SIDM...
F Maccagni at #iaus392#astronomy2024 describes HI stripping data from a MeerKAT survey of the Fornax cluster. I found this plot especially impressive: a *very* clear floor where all the has gets stripped under a certain magnitude
E de Blok kicks off #iaus392#astronomy2024 by summarizing resolved HI observations now and in the near future. One fresh item I thought was especially interesting: "observing" TNG50 and FIRE2 sims just like MEERKAT shows the simulations are not getting the fluffy outskirts right
M Culver at #iaus392#astronomy2024 wraps up the plenary session telling us about how critical multiwavelength data are for understanding near future enormous HI datasets
K Oman kicks off the theory side of #iaus392#astronomy2024 with an overview of how simulations resolve (or sometimes don't!) HI gas in galaxies
