Nonlinear evolution of fast neutrino flavor conversion in the preshock region of core-collapse supernovae
Masamichi Zaizen, Taiki Morinaga
In environments with high dense neutrino gases, such as in core-collapse supernovae, the neutrinos can experience collective neutrino oscillation due to their self-interactions. In…
Three-flavor collective neutrino conversions with multi-azimuthal-angle instability in an electron-capture supernova model
Masamichi Zaizen, Shunsaku Horiuchi, Tomoya Takiwaki +4
We investigate the multi-azimuthal angle (MAA) effect on collective neutrino oscillation by considering the three-dimensional neutrino momentum distribution in a realistic electron…
Neutrino halo effect on collective neutrino oscillation in iron core-collapse supernova model of a 9.6 star
Masamichi Zaizen, John F. Cherry, Tomoya Takiwaki +4
We extend the multi-angle computational framework and investigate the time evolution of the neutrino halo on collective neutrino oscillation in the core collapse of an iron core pr…
Collective neutrino oscillations and detectabilities in failed supernovae
Masamichi Zaizen, Takashi Yoshida, Kohsuke Sumiyoshi +1
We investigate the collective neutrino oscillations under the three flavor multi-angle approximation in a spherically symmetric simulation of failed supernovae. A failed supernova…
Imaging the Schwarzschild-radius-scale Structure of M87 with the Event Horizon Telescope using Sparse Modeling
Kazunori Akiyama, Kazuki Kuramochi, Shiro Ikeda +10
We propose a new imaging technique for radio and optical/infrared interferometry. The proposed technique reconstructs the image from the visibility amplitude and closure phase, whi…
