Isotropy of cosmic rays beyond eV favors their heavy mass composition
Telescope Array Collaboration, R. U. Abbasi, Y. Abe +138
We report an estimation of the injected mass composition of ultra-high energy cosmic rays (UHECRs) at energies higher than 10 EeV. The composition is inferred from an energy-depend…

Mass composition of ultra-high energy cosmic rays from distribution of their arrival directions with the Telescope Array
Telescope Array Collaboration, R. U. Abbasi, Y. Abe +138
We use a new method to estimate the injected mass composition of ultrahigh cosmic rays (UHECRs) at energies higher than 10 EeV. The method is based on comparison of the energy-depe…

Probing Shocked Ejecta in SN 1987A with XRISM-Resolve: the effects of the gate valve closed
Vincenzo Sapienza, Marco Miceli, Aya Bamba +10
Supernova (SN) 1987A is widely regarded as an excellent candidate for leveraging the capabilities of the freshly launched XRISM satellite. Recent researches indicate that the X-ray…
