观测到的伽马射线暴(GRB)使$z=9.4$红移,是早期宇宙中大部分未被探索的$z\sim 2.7-9.4$部分的潜在探测器。因此,找到伽玛暴物理性质之间的相关关系是至关重要的。我们发现,铂伽玛暴数据汇编,与50长伽玛暴,在红移范围$0.553 \leq z \leq 5.0$内有95个长伽玛暴(相对平坦的平台,没有耀斑),而LGRB 95数据汇编,在$0.297 \leq z \leq 9.4$内有95个长伽玛暴,以及两者的145个伽玛暴组合,强烈支持三维(3D)基本平面(Dainotti)相关关系(峰值瞬时亮度、平台发射末端的亮度和其静止帧持续时间之间)对二维相关关系(平台发射末端的亮度和其持续时间之间)的影响。三个数据集中的3D Dainotti相关性是可量化的。我们发现,虽然LGRB 95数据有$\sim50$ %更大的内在散射参数值比质量更好的铂数据,他们提供了宇宙模型和GRB相关参数,也许仅仅是由于大量的数据点,95比50更严格的约束。这表明,当编译伽玛射线暴数据的目的是约束宇宙学参数,鉴于目前的伽玛射线暴数据的质量,内在散射参数的减少必须对减少样本量进行平衡。
英文摘要:
Gamma-ray bursts (GRBs), observed to redshift $z=9.4$, are potential probes of the largely unexplored $z\sim 2.7-9.4$ part of the early Universe. Thus, finding relevant relations among GRB physical properties is crucial. We find that the Platinum GRB data compilation, with 50 long GRBs (with relatively flat plateaus and no flares) in the redshift range $0.553 \leq z \leq 5.0$, and the LGRB95 data compilation, with 95 long GRBs in $0.297 \leq z \leq 9.4$, as well as the 145 GRB combination of the two, strongly favor the three-dimensional (3D) fundamental plane (Dainotti) correlation relation (between the peak prompt lumininosity, the luminosity at the end of the plateau emission, and its rest frame duration) over the two-dimensional one (between the luminosity at the end of the plateau emission and its duration). The 3D Dainotti correlations in the three data sets are standardizable. We find that while LGRB95 data have $\sim50$% larger intrinsic scatter parameter values than the better-quality Platinum data, they provide somewhat tighter constraints on cosmological-model and GRB-correlation parameters, perhaps solely due to the larger number of data points, 95 versus 50. This suggests that when compiling GRB data for the purpose of constraining cosmological parameters, given the quality of current GRB data, intrinsic scatter parameter reduction must be balanced against reduced sample size.

我们表明,王等人和胡等人最近汇编的三个与Dainotti相关的伽马射线暴(GRB)数据集中的每一个,它们一起探测红移范围$0.35 \leq z \leq 5.91$,服从与宇宙模型无关的Dainotti关联关系,因此是可解释的。我们使用这些伽玛暴数据结合目前最好的阿马蒂相关伽玛暴数据,探针$0.3399 \leq z \leq 8.2$,约束宇宙学模型参数。由此产生的宇宙学约束是弱的,提供了非相对论性物质密度参数的下限,温和地支持非零空间曲率,并且在很大程度上与当前加速的宇宙学膨胀以及从更好的数据确定的约束一致。

哈勃常数($H_0$)张力是现代宇宙学中的主要开放问题之一。这种张力是由Ia超新星(SNe Ia)+造父变星组合估算的局部$H_0$值与通过研究宇宙微波背景(CMB)辐射获得的宇宙学$H_0$之间的差异,范围从4到6 $σ$。介绍了Dainotti et al.2021(ApJ)和Dainotti et al.2022(Galvanic)中采用的方法。通过对超新星Ia的Pantheon样本进行分组划分(Scolnic et al. 2018),在每个红移有序的bin中估计了$H_0$的值,并拟合了一个随红移降低的函数。结果表明,随着红移的增加,$H_0$有减小的趋势。如果这不是由于天体物理学的偏差或Ia超新星参数的残余红移演化造成的,那么可以根据修正的引力理论来解释,例如,$f(R)$场景。我们还简要描述了高$z$探测器对哈勃常数张力的可能影响,例如伽马射线暴(GRB)和类星体(QSO),分别在Dainotti等人2022(Galvanie)和Lenart等人2022(ApJ)中报道。
