Most stars form in clusters! 🔭🧪☄️ #galactic

In a new paper led by @alexis-space.bsky.social, we show that >80% of stars in the local Milky Way formed in clusters.

This is *much* higher than other recent estimates (~15%), and supports more traditional 'clustered' models of star formation!

How many stars form in compact clusters in the local Milky Way?

Two main models coexist for the environment in which stars form. The clustered model stipulates that the bulk of star formation occurs within dense embedded clusters, but only a minority of them survi...

Star formation primarily takes place within compact clusters in the local Milky Way! 🌌 #galactic #stellarastro

We've shown this combining the results from two recent, Gaia-based catalogues: the open clusters census from @emily.space and my census of OB stars within 1 kpc!

Kimberly Emig talking about radio recombination lines with the SKA and how to observe them in galaxies through cosmic time! Recent detection of PKS 1830-211 at z=0.89 with MeerKAT and combined with HI & OH can say a lot of gas properties and what kind of a star forming galaxy it is. #skao2025 🔭📡

Slide of all the radio recombination lines that are available in SKA bands.

Graphic of the gravitational lens in which the radio recombination lines were detected.

Slide of the derived properties of the galaxy: density of the gas, star formation rate surface density, SFR = 50 M_Sun/yr

Slide with plots showing the galaxy appears to be a main sequence galaxy, that sits on Kennicutt-Schmidt relation.
