Does the Amati Relation depend on the Luminosity of the GRB＇s Host Galaxy
In order to test the systematics of the Amati relation, 24 long-duration GRBs with available Eγ,iso and Ep are separated into two subgroups according to the B-band luminosity of their host galaxies. The Amati relations in the two subgroups are found to be in agreement with each other within the unce...

| Zusammenfassung: | In order to test the systematics of the Amati relation, 24 long-duration GRBs with available Eγ,iso and Ep are separated into two subgroups according to the B-band luminosity of their host galaxies. The Amati relations in the two subgroups are found to be in agreement with each other within the uncertainties. Taking into account of the well established luminosity - metallicity relation of galaxies, no strong evolution of the Amati relation with the GRB＇s environmental metaUicity is implied in this study. |
