The DAMPE space telescope has directly detected a universal spectral softening at about 15 teravolts across five cosmic-ray species, confirming a rigidity-dependent acceleration framework (the Peters cycle) and ruling out mass-dependent models with over 99.999% confidence, suggesting a nearby Galactic source as the accelerator.
New analysis of DAMPE data finds a universal spectral softening around 15 TeV across multiple high-energy cosmic-ray nuclei, suggesting rigidity—not energy per nucleon—shapes cosmic-ray behavior and tightening constraints on acceleration models; the result, published in Nature, was aided by AI-based event reconstruction and DAMPE’s Silicon-Tungsten Tracker.
A DAMPE study finds a consistent spectral softening in primary cosmic ray nuclei—from protons to iron—occurring around a rigidity of ~15 TV, implying that acceleration and propagation depend on rigidity rather than energy per nucleon; the result, published in Nature, challenges alternative models with 99.999% confidence and narrows the questions about where cosmic rays originate, aided by UNIGE researchers’ AI-based event reconstruction and the DAMPE Silicon-Tungsten Tracker for precise measurements.
