Universality of the Neutrino Collisional Flavor Instability in Core Collapse Supernovae
Jiabao Liu, Hiroki Nagakura, Ryuichiro Akaho +3
Neutrinos are known to undergo flavor conversion processes among the three flavors. The fast flavor conversion (FFC) has been the central piece of flavor conversions taking place i…
Direct Measurement of the Spectral Structure of Cosmic-Ray Electrons+Positrons in the TeV Region with CALET on the International Space Station
O. Adriani, Y. Akaike, K. Asano +77
Detailed measurements of the spectral structure of cosmic-ray electrons and positrons from 10.6 GeV to 7.5 TeV are presented from over 7 years of observations with the CALorimetric…
Fast neutrino-flavor swap in high-energy astrophysical environments
Masamichi Zaizen, Hiroki Nagakura
We assert that non-linear features of fast neutrino-flavor conversion (FFC) can be qualitatively different between core-collapse supernovae (CCSNe) and binary neutron star mergers…
Collisional and Fast Neutrino Flavor Instabilities in Two-dimensional Core-collapse Supernova Simulation with Boltzmann Neutrino Transport
Ryuichiro Akaho, Jiabao Liu, Hiroki Nagakura +2
We present a comprehensive study on the occurrences of the collisional flavor instability (CFI) and the fast flavor instability (FFI) of neutrinos based on a two-dimensional (2D) c…
Observation of gamma rays up to 320 TeV from the middle-aged TeV pulsar wind nebula HESS J1849000
M. Amenomori, S. Asano, Y. W. Bao +115
Gamma rays from HESS J1849000, a middle-aged TeV pulsar wind nebula (PWN), are observed by the Tibet air shower array and the muon detector array. The detection significance of…
Measurement of the Gamma-Ray Energy Spectrum beyond 100 TeV from the HESS J1843033 Region
M. Amenomori, S. Asano, Y. W. Bao +113
HESS J1843033 is a very-high-energy gamma-ray source whose origin remains unidentified. This work presents, for the first time, the energy spectrum of gamma rays beyond $100\, {…
Observations of the Crab Nebula and Pulsar with the Large-Sized Telescope Prototype of the Cherenkov Telescope Array
CTA-LST Project, :, H. Abe +289
CTA (Cherenkov Telescope Array) is the next generation ground-based observatory for gamma-ray astronomy at very-high energies. The Large-Sized Telescope prototype (LST-1) is locate…
Charge-Sign Dependent Cosmic-Ray Modulation Observed with the Calorimetric Electron Telescope on the International Space Station
O. Adriani, Y. Akaike, K. Asano +77
We present the observation of a charge-sign dependent solar modulation of galactic cosmic rays (GCRs) with the CALorimetric Electron Telescope onboard the International Space Stati…
Characterizing quasi-steady states of fast neutrino-flavor conversion by stability and conservation laws
Masamichi Zaizen, Hiroki Nagakura
The question of what ingredients characterize the quasi-steady state of fast neutrino-flavor conversion (FFC) is one of the long-standing riddles in neutrino oscillation. Addressin…
Direct Measurement of the Cosmic-Ray Helium Spectrum from 40 GeV to 250 TeV with the Calorimetric Electron Telescope on the International Space Station
O. Adriani, Y. Akaike, K. Asano +77
We present the results of a direct measurement of the cosmic-ray helium spectrum with the CALET instrument in operation on the International Space Station since 2015. The observati…
Detectability of Late-time Supernova Neutrinos with Fallback Accretion onto Protoneutron star
Ryuichiro Akaho, Hiroki Nagakura, Thierry Foglizzo
We investigate the late-time neutrino emission powered by fallback mass accretion onto proto-neutron star (PNS), using neutrino radiation-hydrodynamic simulations with full Boltzma…
Flavor conversions with energy-dependent neutrino emission and absorption
Chinami Kato, Hiroki Nagakura, Masamichi Zaizen
Fast neutrino flavor conversions (FFCs) and collisional flavor instabilities (CFIs) potentially affect the dynamics of core-collapse supernovae (CCSNe) and binary neutron star merg…
