Gamma-Ray Bursts in Suggest that the Time Variation of the Dark Energy is Small
Yoshiki Kodama, Daisuke Yonetoku, Toshio Murakami +3
We calibrated the peak energy-peak luminosity relation of GRBs (so called Yonetoku relation) using 33 events with the redshift without assuming any cosmological models.…
GRB980425 in the Off-Axis Jet Model of the Standard GRBs
Ryo Yamazaki, Daisuke Yonetoku, Takashi Nakamura
Using a simple off-axis jet model of GRBs, we can reproduce the observed unusual properties of the prompt emission of GRB980425, such as the extremely low isotropic equivalent gamm…
Cosmological X-Ray Flashes from Off-Axis Jets
Ryo Yamazaki, Kunihito Ioka, Takashi Nakamura
The <V/Vmax> of the cosmological X-ray flashes detected by WFC/BeppoSAX is calculated theoretically in a simple jet model. The total emission energy from the jet is assumed to be c…
General Relativistic Numerical Simulation on Coalescing Binary Neutron Stars and Gauge-Invariant Gravitational Wave Extraction
Mari Kawamura, Ken-ichi Oohara, Takashi Nakamura
We are developing 3 dimensional simulation codes for coalescing binary neutron stars. A code using the maximal slicing condition is obtained. To evaluate the gravitational radiatio…
