Simulating accurate observations of star clusters is really annoying! So as a part of this paper, we open sourced all of the code we used to simulate them, and there's a Python notebook that explains how to do it right here: 🔭☄️ #galactic #astrocode

A great paper led by Josefa Großschedl has a appeared on arxiv this morning!
A detailed study on the velocity dispersion of the subgroups of Sco-Cen, the nearest OB association. The expansion of the complex is driven by stellar feedback, engendering a sequential star formation process.

Just about a month until we kick off "Stellar Origins" in Vienna! 👀 Until then, we'll keep you updated here with news on the scientific program and some sneak peeks of what else we have planned for you! Stay tuned and tell your friends! #stellarorigins2025

An exciting paper has appeared today, led by Lily Kormann from the University of Vienna! With the extinction map from Edenhofer et al. (2024), they discovered seven local superclouds, only two of which, The Radcliffe Wave and The Split, were already known!

The Superclouds of the Local Milky Way
Recent 3D dust maps of the local Milky Way are revolutionizing our understanding of the Sun's Galactic neighborhood, bringing much-needed insight into the large-scale organization of the interstellar ...

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!

Cool paper out by Juan D. Soler et al! They looked at the line-of-sight motion of the ISM based on 3D dust maps, HI and CO line emission, creating several maps of how the dust and gas in our solar neighborhood move! 🔭🧪

I'm not sure I'm emotionally prepared to say goodbye to Gaia. This video, shared by @esa.int, is the spacecraft fading from view for the final time. It's still alive, but will be switched off on Thursday. 🔭 www.youtube.com/watch?v=-NGh...

New result from MPIA: Two of our astronomers have taken a look at just how "dirty" our window into deep space is, concretely: they have mapped the properties of dust out there in the Milky Way, including how that dust absorbs light. www.mpia.de/news/science...
Astronomy’s dirty window to space
Astronomers from the Max Planck Institute for Astronomy have constructed the first detailed 3D map of the properties of cosmic dust in our home galaxy.

Interesting paper out today by Efrem Maconi, @joaoalves.bsky.social et al.! They find that the Sun probably passed through a massive wave of interstellar dust and gas (the Radcliffe wave) around 11 to 18 million years ago. 🔭🧪 #milkyway #planetsci arxiv.org/abs/2502.16360
