Para peneliti yang menggunakan teleskop ruang angkasa DAMPE telah mengidentifikasi pelemahan spektral yang sama pada sinar kosmik di berbagai jenis partikel. Pola tersebut muncul pada rigiditas sekitar 15 teraelektron-volt untuk proton hingga inti besi. Temuan ini, yang diterbitkan dalam Nature, menawarkan wawasan baru tentang bagaimana partikel berenergi tinggi ini berperilaku di galaksi.

Selama lebih dari satu abad, para ilmuwan telah mempelajari sinar kosmik, partikel paling energetik yang dikenal di alam. Data dari misi DAMPE, yang diluncurkan pada Desember 2015, kini menunjukkan bahwa jumlah partikel ini menurun drastis setelah melewati ambang batas rigiditas yang sama. Efek tersebut berlaku bagi proton, helium, karbon, oksigen, serta inti besi.

Ultraheavy nuclei may explain Amaterasu particle origin

New research suggests the Amaterasu particle, one of the most energetic cosmic rays detected, could be an ultraheavy atomic nucleus rather than a proton. The findings, from scientists at Penn State, were published in Physical Review Letters. They indicate such nuclei could retain extreme energy over vast distances in space.

New model proposes dark matter made of two particles to explain Milky Way gamma-ray excess

Building on prior detections of gamma-ray emissions from the Milky Way's center, physicists led by Gordan Krnjaic at Fermilab propose dark matter consists of two distinct particles that interact to produce detectable signals. This resolves the puzzle of signals in the Milky Way but none in dark-matter-rich dwarf galaxies, as observed by the Fermi Gamma-ray Space Telescope.

Particles emerge from vacuum in proton collisions for first time

Physicists with the STAR collaboration have observed particles emerging directly from empty space during high-energy proton collisions at Brookhaven National Laboratory. The experiment provides strong evidence that mass can arise from vacuum fluctuations, as predicted by quantum chromodynamics. Quark-antiquark pairs promoted to real particles retained spin correlations tracing back to the vacuum.

Scientists have detected traces of iron-60 in Antarctic ice up to 80,000 years old, showing that the solar system is moving through material from an ancient stellar explosion. The findings come from a study published in Physical Review Letters and point to the Local Interstellar Cloud as the source of the radioactive isotope.
