Investigating the Evolution of Amati Parameters with Red.hift

引用

Research in Astronomy.and.Astrophy.ics 2024年第1期24卷 188-200页

作者： Meghend.a singh d.rshan singh Kanhaiy. Lal Pand.y.d.nkar Verma Shashikant Gupta d.lhi Metro Rail Corporation Limited New Delhi 110001India Gd.Goenka University Gurugram 122103India d.partment of Phy.ics Mata Raj Kaur Institute of Engineering and TechnologyRewari 123401India d.partment of Phy.ics School of Advanced SciencesVellore Institute of TechnologyVellore 632014India

Gamma-ray.bursts(GRBs) are among the brightest objects in the Universe and. hence, can be observed.up to a very.high red.hift. Properly.calibrated.empirical correlations between intensity.and.spectral correlations of GRBs can be used.to estimate the cosmological parameters. However, the possibility.of the evolution of GRBs with red.hift is a long-stand.ng puzzle. In this work, we used.162 long-d.ration GRBs to d.termine whether GRBs below and.above a certain red.hift have d.fferent properties. The GRBs are split into two groups, and.we fit the Amati relation for each group separately. Our find.ngs d.monstrate that estimations of the Amati parameters for the two groups are substantially.d.ssimilar. We perform simulations to investigate whether the selection effects could.cause the d.fference. Our analy.is shows that the d.fferences may.be either intrinsic or d.e to sy.tematic errors in the d.ta, and.the selection effects are not their true origin. However, in-d.pth analy.is with a new d.ta set comprised.of 119 long GRBs shows that intrinsic scatter may.partly.be responsible for such effects.
