Redshift Dependent Lag-Luminosity Relation in 565 BASTE Gamma Ray Bursts
Ryo Tsutsui, Takashi Nakamura, Daisuke Yonetoku +3
We compared redshifts from Yonetoku relation and from the lag-luminosity relation for 565 BASTE GRBs and were surprised to find that the correlation is very low. As…
A Unified Model for Gamma-Ray Bursts
Ryo Yamazaki, Kunihito Ioka, Takashi Nakamura +1
A possible unified model of short and long gamma-ray bursts (GRBs), X-ray rich GRBs, and X-ray flashes is proposed. It is assumed that the jet of a GRB consists of many emitting su…
Near-Infrared Colors of Gamma-Ray Burst Afterglows and Cosmic Reionization History
Akio K. Inoue, Ryo Yamazaki, Takashi Nakamura
Using the near-infrared (NIR) observations of the afterglows of the high redshift ($5 \la z \la 25$) gamma-ray bursts (GRBs) which will be detected by the {\it Swift} satellite, we…
A Model for Non High Energy Gamma Ray Bursts and Sources of Ultra High Energy Cosmic Rays
Takashi Nakamura
As a progenitor of NHE (Non High Energy) GRBs, we propose a (C+O) star and a neutron star (black hole) close binary system. Since the (C+O) star is tidally locked, a new born pulsa…
