We hope it becomes a go-to resource for the community! Check out the details and a quick intro video above.

🔬 Why does this matter? For models where dark matter talks to the strong force, these effects can change predictions by orders of magnitude. Getting them right is essential for accurate predictions that can guide experiments. Our tool integrates this into a standard workflow with minimal fuss.

We've built SE+BSF4DM—a new code patch for the popular micrOMEGAs package. It finally makes including tricky but crucial quantum effects (Sommerfeld enhancement & bound-state formation) in dark matter calculations simple and accessible for everyone.

🎉 It's paper day! I'm absolutely thrilled to announce our new preprint!

Man sollte ihn bauen! Die wissenschaftlichen Erkenntnisse für die Physik und das technologische Know-How sollten Motivation genug sein. Auf eine Entdeckung zu warten, die uns vorgibt, welche Experimente optimal wären, würde meiner Meinung nach bedeuten, dass wir unter unseren Möglichkeiten bleiben!

Seems like Santa 🎅- or better, the Austrian version of it, the Christkind 👼 - wants me to go back to the basics 🤩📚
