Kavli Affiliate: Naoki Yasuda | First 5 Authors: Takashi J. Moriya, Ji-an Jiang, Naoki Yasuda, Mitsuru Kokubo, Kojiro Kawana | Summary: Some supernovae such as pair-instability supernovae are predicted to have the duration of more than a year in the observer frame. To constrain the rates of supernovae lasting for more than a year, we […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Taisuke Katayose, Shigeki Matsumoto, Satoshi Shirai, , | Summary: Electroweakly Interacting Massive Particles (EWIMPs), in other words, new massive particles that are charged under the electroweak interaction of the Standard Model (SM), are often predicted in various new physics models. EWIMPs are probed at hadron collider experiments […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Zahra Tabrizi, Shunsaku Horiuchi, , , | Summary: Although Galactic core-collapse supernovae (SNe) only happen a few times per century, every hour a vast number of explosions happen in the whole universe, emitting energy in the form of neutrinos, resulting in the diffuse supernova neutrino background (DSNB). […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Shusuke Ueda, , , | Summary: Affleck-Dine inflation is a recently proposed model in which a single complex scalar field, nonminimally coupled to gravity, drives inflation and simultaneously generates the baryon asymmetry of universe via Affleck-Dine mechanism. In this paper we investigate the supersymmetric implementation […]
Kavli Affiliate: Shinichiro Takeda | First 5 Authors: Kouichi Hagino, Hirokazu Odaka, Goro Sato, Tamotsu Sato, Hiromasa Suzuki | Summary: Understanding and reducing the in-orbit instrumental backgrounds are essential to achieving high sensitivity in hard X-ray astronomical observations. The observational data of the Hard X-ray Imager (HXI) on board the Hitomi satellite provides useful information […]

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Masamichi Zaizen, Shunsaku Horiuchi, Tomoya Takiwaki, Kei Kotake, Takashi Yoshida | Summary: We investigate the multi-azimuthal angle (MAA) effect on collective neutrino oscillation by considering the three-dimensional neutrino momentum distribution in a realistic electron-capture supernova model with an $8.8 M_{odot}$ progenitor. We find that the MAA effect […]
Kavli Affiliate: Yasunori Nomura | First 5 Authors: Yasunori Nomura, , , , | Summary: We portray the structure of quantum gravity emerging from recent progress in understanding the quantum mechanics of an evaporating black hole. Quantum gravity admits two different descriptions, based on Euclidean gravitational path integral and a unitarily evolving holographic quantum system, […]
Kavli Affiliate: Takeo Higuchi | First 5 Authors: Satoshi Higashino, Yuichiro Mori, Yosuke Takubo, Takeo Higuchi, Akimasa Ishikawa | Summary: The technique of weak value amplification, proposed by Aharonov et al. in 1988, has been applied for various fields of physics for the purpose of precision measurement, which is made possible by exploiting the freedom […]
