Constraints on $w_{0}$ and $w_{a}$ of Dark Energy from High Redshift Gamma Ray Bursts

Ryo Tsutsui, Takashi Nakamura, Daisuke Yonetoku +4

We extend the Hubble diagram up to $z = 5.6$ 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 $1.8 < z < 5.6$ 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 $z < 1.62$ 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 $z_{Y}$ from Yonetoku relation and $z_{l a g}$ from the lag-luminosity relation for 565 BASTE GRBs and were surprised to find that the correlation is very low. As…
