Cosmological X-ray Flashes in the Off-Axis Jet Model
Ryo Yamazaki, Kunihito Ioka, Takashi Nakamura
The <V/Vmax> of the cosmological X-ray flashes detected by Wide Field Cameras on BeppoSAX is calculted theoretically in a simple jet model. The total emission energy from the jet i…
Delayed Flashes from Counter Jets of Gamma Ray Bursts
Ryo Yamazaki, Kunihito Ioka, Takashi Nakamura
If X-ray flashes are due to the forward jet emissions from gamma ray bursts (GRBs) observed with large viewing angles, we show that a prompt emission from a counter jet should be o…
X-ray Flashes from Off-axis Gamma-Ray Bursts
Ryo Yamazaki, Kunihito Ioka, Takashi Nakamura
Ioka and Nakamura (2001) proposed a simple jet model that is compatible with the peak luminosity-spectral lag relation, the peak luminosity-variability relation and various other r…
