Intrisic Dispersion of Correlations among Ep, Lp, and Eiso of Gamma Ray Bursts depends on the quality of Data Set

Ryo Tsutsui, Takashi Nakamura, Daisuke Yonetoku +2

We reconsider correlations among the spectral peak energy ( $E_{p}$ ), 1-second peak luminosity ( $L_{p}$ ) and isotropic energy (\Eiso), using the database constructed by \citet{yonetoku1…

Testing two-component jet models of GRBs with orphan afterglows

Kohei Inayoshi, Ryo Tsutsui

In the \swift era, two-component jet models were introduced to explain the complex temporal profiles and the diversity of early afterglows. In this paper, we concentrate on the two…
