Constraints on and of Dark Energy from High Redshift Gamma Ray Bursts
Ryo Tsutsui, Takashi Nakamura, Daisuke Yonetoku +4
We extend the Hubble diagram up to using 63 gamma-ray bursts (GRBs) via peak energy-peak luminosity relation (so called Yonetoku relation), and obtain constraints on cosm…

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.…

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…
