20 terabytes a night from Rubin's LSST — how do you keep up? At the Oskar Klein Centre, cosmoTRON, a multi-agent system running on a hand-sized #NVIDIA #DGXSpark, just reproduced a standard cosmology analysis on its own. Proof of concept, but promising. 👉 www.su.se/english/divi... #cosmology #AI

Shape beats material: in telescopes hunting the Big Bang's afterglow, millimetre-scale pyramids absorb >99.7% of stray microwaves — and their shape matters more than what they're made of. New Oskar Klein Centre study, Editors' Pick in Applied Optics @optica.org . #CMB #cosmology #physics

It's cool #PaperDay today @oskarkleincentre.bsky.social, #Astronomy #Cosmology! arxiv.org/abs/2602.02363 We used a physics informed Field Level Inference method applied to a large Quasar sample to reconstruct the inicial conditions, matter field and dynamics of the Universe at the largest scales!

We present a method that connects statistical mechanics and Bayesian inference via Ising marginalization for binary uncertainties, with open code. @arxiv.bsky.social #Physics #Statistics #IsingModel #OpenSource #Python #statsky

What powers the most extreme phenomena in the Universe—and what could they reveal about dark matter? Join us and explore high-energy astrophysics, particle acceleration, and beyond-standard-model signals in the non-thermal Universe. Spring 2026 • 7.5 credits • Online via Zoom. shorturl.at/mTg1k

A recent paper in #MNRAS - an international collaboration with 11 OKC researchers involved.

You are welcome to join the zoom event on high energy physics on October 30th at 13.00! Speakers: Frank Wilczek, Sara Strandberg, Oksana Iarygina, and Oliver Schlotterer. The event will be moderated by Jonas Enander. You'll find the zoom link here: indico.fysik.su.se/event/9415/ Welcome!
