X-ray imaging at synchrotron research facilities / Ponchut, Cyril (ESRF, Grenoble) ; Tartoni, Nicola (Diamond Light Source) ; Pennicard, David (DESY)
At synchrotron facilities, many X-ray imaging and diffraction experiments require pixel detectors with minimal noise, high speed and reasonably small pixel size, all of which can be achieved with the Medipix ASIC family. [...]

Radiation Reaction from Soft Theorems / Di Vecchia, Paolo ; Heissenberg, Carlo ; Russo, Rodolfo ; Veneziano, Gabriele
Radiation reaction (RR) terms at the third post-Minkowskian (3PM) order have recently been found to be instrumental in restoring smooth continuity between the non-relativistic, relativistic, and ultra-relativistic (including the massless) regimes. [...]
