Scattered Short Gamma-Ray Bursts as Electromagnetic Counterparts to Gravitational Waves and Implications of GW170817 and GRB 170817A
Shota Kisaka, Kunihito Ioka, Kazumi Kashiyama +1
In the faint short gamma-ray burst sGRB 170817A followed by the gravitational waves (GWs) from a merger of two neutron stars (NSs) GW170817, the spectral peak energy is too high to…
Radio Transients from Newborn Black Holes
Kazumi Kashiyama, Kenta Hotokezaka, Kohta Murase
We consider radio emission from a newborn black hole (BH), which is accompanied by a mini-disk with a mass of . Such a disk can be formed from an outer edge of th…
Detectability of thermal neutrinos from binary-neutron-star mergers and implication to neutrino physics
Koutarou Kyutoku, Kazumi Kashiyama
We propose a long-term strategy for detecting thermal neutrinos from the remnant of binary-neutron-star mergers with a future M-ton water-Cherenkov detector such as Hyper-Kamiokand…
Mass Ejection in Failed Supernovae: Variation with Stellar Progenitor
Rodrigo Fernández, Eliot Quataert, Kazumi Kashiyama +1
We study the ejection of mass during stellar core-collapse when the stalled shock does not revive and a black hole forms. Neutrino emission during the protoneutron star phase cause…
Rapidly Rising Optical Transients from the Birth of Binary Neutron Stars
Kenta Hotokezaka, Kazumi Kashiyama, Kohta Murase
We study optical counterparts of a new-born pulsar in a double neutron star system like PSR J0737-3039A/B. This system is believed to eject a small amount of mass of $\mathcal{O}(0…
Radio Emission from Embryonic Super-Luminous Supernova Remnants
Conor M. B. Omand, Kazumi Kashiyama, Kohta Murase
It has been widely argued that Type-I super-luminous supernovae (SLSNe-I) are driven by powerful central engines with a long-lasting energy injection after the core-collapse of mas…
Large-scale clustering as a probe of the origin and the host environment of fast radio bursts
Masato Shirasaki, Kazumi Kashiyama, Naoki Yoshida
We propose to use degree-scale angular clustering of fast radio bursts (FRBs) to identify their origin and the host galaxy population. We study the information content in autocorre…
Testing the Young Neutron Star Scenario with Persistent Radio Emission Associated with FRB 121102
Kazumi Kashiyama, Kohta Murase
Recently a repeating fast radio burst (FRB) 121102 has been confirmed to be an extragalactic event and a persistent radio counterpart has been identified. While other possibilities…
