The emergence of globular clusters and globular-cluster-like dwarfs - Nature The results from a state-of-the-art suite of hydrodynamical cosmological zoom-in simulations show how globular clusters naturally emerge in the Standard Cosmology and also reveal the existence of a ne...

Big news! @astroeth.bsky.social has his Nature paper on the Emergence of Globular Clusters out today! His simulations have globulars forming naturally, as well as some cool globular cluster like dwarfs! Check it out! 🔭🧪☄️

EDGE: A new model for Nuclear Star Cluster formation in dwarf galaxies Nuclear Star Clusters (NSCs) are amongst the densest stellar systems in the Universe and are found at the centres of many bright spiral and elliptical galaxies, and up to ${\sim}$40% of dwarf...

Paper day! Izzy Gray proposes a new model for NSC formation in very low mass dwarfs. Model prediction: NSCs should have CMDs with >2, distinct, main sequence turnoffs. Some nearby CGs like OCen and M54 show exactly this behaviour, suggesting they could be accreted NSCs! 🔭

Justin at the front of the lecture theatre, giving a talk about dark matter 🔭

We're back with our stargazing nights at the university of Surrey! This is the first time we've been able to host one since COVID, and true to form, the skies are cloudy 😅 but, we have an excellent talk from @readdark.bsky.social to make up for it 🧪🔭

We're hiring cosmology / large-scale structure postdocs at UT Austin! If you're interested in analysis or cosmological interpretation of HETDEX (BAO survey) data, or related science, please apply! More info is linked below; feel free to be in touch with me as well.

Referee: "I feel the paper could be more concise and less repetitive. Or, to put it another way, it could be less repetitive and more concise."

Since so many have asked, here’s my hot take on the spherules Loeb found and the manuscript he’s loudly rushed to the world. These are pretty typical cosmic spherules. Had he done the *obvious*--a control sample 100 km away from the meteor--he’d have found the same thing. 1/20

Sounds better than "X-ing" ... !

Thanks! And hello world! What do we call posting here? 🔭
