Interesting new result from our Maximilian Häberle, Nadine Neumayer and colleagues: in a needle-in-a-haystack process using mostly archival data, they found fast-moving stars indicating the presence of an intermediate-mass black hole in omega Centauri mpia.de/news/science/2…

GALAH DR4 is now public! 10 years of observations, 995 nights (incl. rainy/snowy/cloudy ones), 32 elements (incl. nitrogen), 0.92 Mio. stars, 1.09 Mio. spectra, thanks to an amazing group of observers, engineers, and astronomers. Paper: arxiv.org/abs/2409.19858 with links to data.

The GALAH DR4 data release is out! ONE MILLION STARS! Here's our modified element table (including our data for 30 elements) - figure by Sven Buder. The other figures show theoretical time dependencies from Kobayashi, Karakas & Lugaro 2020. GALAH Survey Sydney Institute for Astronomy (SIfA)
