Proton Acceleration by Collisionless Shocks in Supermassive Black Hole Coronae: Implications for High-Energy Neutrinos
Minh Nhat Ly, Yoshiyuki Inoue, Yasuhiko Sentoku +1
Recent observations by the IceCube Neutrino Observatory have revealed a significant excess of high-energy neutrinos from nearby Seyfert galaxies, such as NGC~1068, without a corres…

Enhancement of J x B electron acceleration with the micro-structured target and picosecond high-contrast relativistic-intensity laser pulse
Ryunosuke Takizawa, Yuga Karaki, Hiroki Matsubara +8
Efficient generation of multi-hundred-keV electrons is essential for isochoric heating and can influence ion acceleration. We investigated electron acceleration from copper-oleate…

Enhanced plasma heating via interaction with high-contrast laser and cone-shaped target
Yuga Karaki, Yoshitaka Mori, Eigo Ebisawa +25
We investigated plasma heating enhancement using a high-intensity, high-contrast laser and a cone-attached target. Fast electron spectra and X-ray emission were measured with an el…
