论文摘要
在本文中,根据最近的快速无线电爆发(FRB)天文学的观察性发展,我们更新了有关超导宇宙字符串(SCS)的限制。假设字符串遵循以电流为特征的指数分布,我们表明在我们上下文中的两个参数是特征性张力($gμ$),并且可以通过FRB实验来限制上述指数分布($ i_c $)的参数。特别是,我们研究了Parkes和Askap的数据集。我们浏览了一个参数空间,其中$gμ\ sim [10^{ - 17},10^{ - 12}] $和$ i_c \ sim [10^{ - 1},10^{2}] $ GEV,并发现我们的结果表明,我们与askap共同限制了SCSS的parkes可以约束SCSS的参数空间。
In this article we update constraints on superconducting cosmic strings (SCSs) in light of the recent observational developments of fast radio bursts (FRBs) astronomy. Assuming strings follow an exponential distribution characterized by current, we show that two parameters in our context, which are the characteristic tension ($Gμ$) and a parameter which describes the aforementioned exponential distribution ($I_c$), can be constrained by FRB experiments. Particularly, we investigate data sets from Parkes and ASKAP. We looked through a parameter space where $Gμ\sim [10^{-17}, 10^{-12}]$ and $I_c\sim [10^{-1}, 10^{2}]$ GeV, and found our results show that Parkes jointly with ASKAP can constrain the parameter space for SCSs.
