摘要:

GW170817/GRB170817A的探测表明,短伽马射线暴(SGRB)与产生引力波(GW)的双中子星(BNS)并合之间存在紧密关联。为确认这种关联并揭示BNS并合的物理过程,还需要更多证据。即将开展的High Altitude Detection of Astronomical Radiation(HADAR,高海拔天文辐射探测)实验凭借宽视场(FOV)以及在数十GeV以上的大有效面积,有望及时探测甚高能(VHE;>10 GeV)SGRB。本文旨在模拟并分析未来引力波探测器网络与HADAR协同进行的GW/SGRB联合探测,其中探测器网络包括第二代LIGO、Virgo和KAGRA,以及第三代ET和CE。我们简要介绍用于SGRB模拟的HADAR实验及其预期的SGRB探测情况。对于GW模拟,我们采用唯象模型描述BNS并合产生的GW,并引入信噪比(SNR)作为探测器响应。在理论分析之后,我们计算了GW探测器网络随红移变化的效率函数。随后,我们通过蒙特卡洛抽样构建GW探测模拟。作为检验,我们将LIGO-Virgo O2和O3运行的模拟结果与其实际探测进行比较。随后讨论用于联合探测的GW与SGRB模型组合,包括参数相关性、触发SNR和效率天图。在不同可能配置下,LHVK网络与HADAR的估计联合探测率为每年0.09–2.52次,而ET+CE网络与HADAR的估计联合探测率约为每年0.27–7.89次。

英文摘要:

The detection of GW170817/GRB170817A implied the strong association between short gamma-ray bursts (SGRBs) and binary neutron star (BNS) mergers which produce gravitational waves (GWs). More evidence is needed to confirm the association and reveal the physical processes of BNS mergers. The upcoming High Altitude Detection of Astronomical Radiation (HADAR) experiment, excelling in a wide field of view (FOV) and a large effective area above tens of GeV, is a hope for the prompt detection of very-high-energy (VHE; > 10 GeV) SGRBs. The aim of this paper is to simulate and analyse GW/SGRB joint detections by future GW detector networks in synergy with HADAR, including the second generation LIGO, Virgo and KAGRA and the third generation ET and CE. We provide a brief introduction of the HADAR experiment for SGRB simulations and its expected SGRB detections. For GW simulations, we adopt a phenomenological model to describe GWs produced by BNS mergers and introduce the signal-noise ratios (SNRs) as detector responses. Following a theoretical analysis we compute the redshift-dependent efficiency functions of GW detector networks. We then construct the simulation of GW detection by Monte Carlo sampling. We compare the simulated results of LIGO-Virgo O2 and O3 runs with their actual detections as a check. The combination of GW and SGRB models is then discussed for joint detection, including parameter correlations, triggered SNRs and efficiency skymaps. The estimated joint detection rates are 0.09-2.52 per year for LHVK network with HADAR under different possible configurations, and approximately 0.27-7.89 per year for ET+CE network with HADAR.
