Cosmological Constraints from calibrated Yonetoku and Amati relation implies Fundamental plane of Gamma-ray bursts
Ryo Tsutsui, Takashi Nakamura, Daisuke Yonetoku +3
We consider two empirical relations using data only from the prompt emission of Gamma-Ray Bursts (GRBs), peak energy () - peak luminosity () relation (so called Yonetoku…
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…
Absolute Rate, Evolving Luminosity function, and Evolving Jet Opening Angle Distribution for Long Gamma-Ray Bursts
Tatsushi Matsubayashi, Ryo Yamazaki, Daisuke Yonetoku +2
Using the luminosity function and the apparent GRB rate inferred from the spectral peak energy-luminosity relation, we investigate the absolute GRB formation rate, taking into acco…
The Reionization History and Early Metal Enrichment inferred from the Gamma-Ray Burst Rate
T. Murakami, D. Yonetoku, M. Umemura +2
Based on the gamma-ray burst (GRB) event rate at redshifts of , which is assessed by the spectral peak energy-to-luminosity relation recently found by Yonetoku et…
