The smallest-ever force field map of nature.

Physicists have mapped the forces acting inside a #proton, showing in unprecedented detail how #quarks—the tiny #particles within—respond when hit by high-energy #photons.

The new result breaks down #space and #time into a fine grid, allowing simulating how the strong force—the fundamental interaction that binds quarks into #protons and #neutrons—varies across different regions inside the proton.

Phys.org · Scientists map the forces acting inside a protonBy Rhiannon Koch

[#Pulsars, these #particles accelerators] When particles (electrons, protons, nuclei) enter their field, they are accelerated. Confined, they form a #gamma halo around these compact objects. Pulsars with gamma halo are windows, magnifying glasses, on the enigmatic #CosmicRayings.

Focus on the #GALAMO project led by IRAP astronomer Pierrick Martin: irap.omp.eu/en/2025/02/studyin. The target: pulsars with gamma halo.

“What if pulsars played an essential role in the evolution of #galaxies and the formation of #stars on a cosmic scale?” 🤔 😵🧐
