论文摘要
在伽马射线的Konus-wind目录的第二部分中,有已知的红移(第一部分:Tsvetkova等人,2017; t17),我们介绍了对伽马射线爆发(GRB)进行系统研究的结果,并通过Konus-Wind(Kwind(KW)同时检测到的可靠的红移估计(在KWind(KW)中)(在KWind(KW)中)的结果(kwind(kw))的结果(从2005年1月到2018年底的时期。通过利用BAT的高灵敏度和KW的宽光谱,我们能够限制167个弱弱的弱较弱,相对较软的GRB(包括四个短突发)的关节KW-BAT样品的峰值光谱能量,宽带能量和峰值通量。基于GRB红移,该范围跨越了$ 0.04 \ leq Z \ leq 9.4 $,我们估计其剩余框架,各向同性等效的能量和峰值光度。对于14个GRB具有相当约束的喷射断裂,我们提供了能量学的准校正值。这项工作将具有已知红移的KW GRB的样品扩展到了338 GRB,这是迄今为止在宽阔的能量带上研究的最大宇宙学GRB。借助完整的KW样本,考虑了仪器偏差,我们探讨了GRB静止框架的特性,包括硬度强度相关性,GRB发光度的演变,发光度和各向同性能量函数以及GRB形成速率的演变,我们认为这与T17和其他研究相吻合。
In the Second part of The Konus-Wind Catalog of Gamma-Ray Bursts with Known Redshifts (first part: Tsvetkova et al. 2017; T17), we present the results of a systematic study of gamma-ray bursts (GRBs) with reliable redshift estimates detected simultaneously by the Konus-Wind (KW) experiment (in the waiting mode) and by the Swift/BAT (BAT) telescope during the period from 2005 January to the end of 2018. By taking advantage of the high sensitivity of BAT and the wide spectral band of KW we were able to constrain the peak spectral energies, the broadband energy fluences, and the peak fluxes for the joint KW-BAT sample of 167 weak, relatively soft GRBs (including four short bursts). Based on the GRB redshifts, which span the range $0.04 \leq z \leq 9.4$, we estimate the rest-frame, isotropic-equivalent energy, and peak luminosity. For 14 GRBs with reasonably constrained jet breaks, we provide the collimation-corrected values of the energetics. This work extends the sample of KW GRBs with known redshifts to 338 GRBs, the largest set of cosmological GRBs studied to date over a broad energy band. With the full KW sample, accounting for the instrumental bias, we explore GRB rest-frame properties, including hardness-intensity correlations, GRB luminosity evolution, luminosity and isotropic-energy functions, and the evolution of the GRB formation rate, which we find to be in general agreement with those reported in T17 and other previous studies.
