Detectability of Pair Echos from Gamma-Ray Bursts and Intergalactic Magnetic Fields
Keitaro Takahashi, Kohta Murase, Kiyotomo Ichiki +2
High-energy emission from gamma-ray bursts (GRBs) can give rise to pair echos, i.e. delayed inverse Compton emission from secondary pairs produced in interactions w…
High energy neutrino early afterglows from gamma-ray bursts revisited
Kohta Murase
The high energy neutrino emission from gamma-ray bursts (GRBs) has been expected in various scenarios. In this paper, we study the neutrino emission from early afterglows of GRBs,…
Cosmogenic neutrinos as a probe of the transition from Galactic to extragalactic cosmic rays
Hajime Takami, Kohta Murase, Shigehiro Nagataki +1
There are two promising scenarios that explain the ankle, which is a dip in the spectrum of cosmic rays at eV. A scenario interprets the ankle as the transition from…
High Energy Neutrino Flashes from Far-Ultraviolet and X-ray Flares in Gamma-Ray Bursts
Kohta Murase, Shigehiro Nagataki
The recent observations of bright optical and x-ray flares by the Swift satellite suggest these are produced by the late activities of the central engine. We study the neutrino emi…
High Energy Neutrino Emission and Neutrino Background from Gamma-Ray Bursts in the Internal Shock Model
Kohta Murase, Shigehiro Nagataki
High energy neutrino emission from GRBs is discussed. In this paper, by using the simulation kit GEANT4, we calculate proton cooling efficiency including pion-multiplicity and prot…
