Excited to share with you an exciting project with Jacky Yip @uwmadphysics.bsky.social and Charles Arnal and Francois Charton at Meta where we develop a transformer model to automate the generation of Calabi-Yau manifolds, extra dimensional spaces in string theory: arxiv.org/abs/2507.03732

First images from world's largest digital camera reveal galaxies and cosmic collisions Astronomers have been eagerly anticipating the images from the Vera C. Rubin Observatory, which experts say could help solve some of the universe's most enduring mysteries.

Stunning first images from the world’s largest digital camera at the Vera C. Rubin Observatory. And big shoutout to @uwmadphysics.bsky.social associate professor Keith Bechtol who helped make this celestial milestone happen! 🔭🪐✨

At the #RubinFirstLook watch party @uwmadphysics.bsky.social

UW–Madison physicists play key role in international observatory Physics professor Keith Bechtol and his research group have been key players in bringing the Vera C. Rubin Observatory in Chile to the main stage. Now its state-of-the-art telescope has started taking

First images of the greatest cosmic movie ever made will be released by the Vera C. Rubin Observatory on Monday, and one of the “directors” is @uwmadphysics.bsky.social
Prof. Keith Bechtol. Join the watch party to learn more about the observatory and UW–Madison’s involvement!

Congrats to physics instrument maker Bill Foster!

Attosecond inner-shell lasing at ångström wavelengths - Nature Strong lasing effects similar to those in the optical regime can occur at 1.5–2.1 Å wavelengths during high-intensity XFEL-driven Kα1 lasing of copper and manganese.

Bergmann Group achieves shortest hard X-ray pulses to date Once only a part of science fiction, lasers are now everyday objects used in research, healthcare and even just for fun. Previously available only in low-energy light, lasers are now available in wave...

Today in @nature.com, Uwe Bergmann's group, with colleagues at SLAC, SACLA, and others, demonstrated generating the shortest (~100 attosecond!) X-ray pulses ever through the first demonstration of strong lasing phenomena.

In the search for the elusive sterile neutrino, UW–Madison and NOvA scientists *still* didn't find any — but their work puts the tightest constraints on parameter space to date for where sterile neutrinos could be found. #Physics #Neutrinos

Formulating the Weak Gravity Conjecture in AdS Space We propose a version of the Weak Gravity Conjecture that applies to AdS spacetime. We find that the condition on the charge-to-mass ratio of a charged particle in AdS$_D$ spacetime is corrected compar...

New paper alert! With Puxin Lin and Alessandro Mininno
@uwmadphysics.bsky.social we formulate the Weak Gravity Conjecture in Anti de Sitter Space: arxiv.org/abs/2503.05862 Interesting plot twist about BPS states and the Weak Gravity Conjecture!

NOvA study sets tighter limit on sterile neutrinos Neutrinos have always been difficult to study because their small mass and neutral charge make them especially elusive. Scientists have made a lot of headway in the field and can now detect three flav...

UW–Madison physicists with the #NOvA collaboration led a new study in PRL that "sets some of the strongest limits on the existence of the sterile #neutrinos," according to lead author Adam Lister. @fermilab.bsky.social
