News from our group
As in the previous year, "AG Sfienti & Friends" is the best university sub-team! We managed to cycle nearly 2081 km in three weeks. This is more than 400 km more than last year!
Thanks everyone for their great efforts!

Fancy studying neutron stars without leaving Earth?
We are recruiting a PhD student in Nuclear Astrophysics. We use accelerator-based experiments to understand the properties of neutron stars and the nuclear reactions that power stars.
Join us in Mainz and work on the nuclear physics behind stars
Open call for applications: June 8 to July 8, 2026

To boldly measure where no one has measured before...
With our next transverse asymmetry beam time at A1, we go for the final frontier: taking data with a 208Pb target at 210 MeV!
The beam time will run from the 17th of November until the 2nd of December.
