Limitation on the Viewing Angles of Long GRBs Based on Amati Relation

基于 Amati 关系对长伽马暴观测视角的限制

Y. Q. Lin, H. L. Jiang

原文摘要Abstract

Fermi, Swift, and other observation satellites provided a dataset of 323 Long Gamma-Ray Bursts (LGRBs) with known redshift and well-defined spectral parameters spanning from February 1997 to September 2023. Among these, 123 GRBs (Gamma-Ray Bursts) observed by Fermi-GBM were selected to calibrate the relationship between the isotropic energy $E_{\rm{iso}}$ and the peak energy in the cosmological rest frame $E_{\rm{p,i}}$, known as the Amati relation. The analysis revealed that the $E_{\rm{iso}}$ of five LGRBs (GRB 980425, GRB 061210, GRB 070714B, GRB 071227, and GRB 080123A) significantly deviated from the Amati relation, suggesting that the jet of them may be off-axis to the line of sight. Utilizing the well-established $E_{\rm{p,i}}-\varGamma$ and $E_{\rm{p,i}}-E_{\rm{iso}}$ correlations, we estimated the viewing angles $\theta _{\rm{obs}}^{'}$ for these five LGRBs. The results show, $\theta^{'}_{\rm{obs}}=(0.42^{+0.29}_{-0.14})^\circ$ for GRB 980425, $\theta^{'}_{\rm{obs}}=(0.27^{+0.21}_{-0.10})^\circ$ for GRB 061210, $\theta^{'}_{\rm{obs}}=(0.10^{+0.09}_{-0.02})^\circ$ for GRB 070714B, $\theta^{'}_{\rm{obs}}=(0.13^{+0.09}_{-0.05})^\circ$ for GRB 071227, and $\theta^{'}_{\rm{obs}}=(0.12^{+0.14}_{-0.03})^\circ$ for GRB 080123A. Notably, all five $\theta _{\rm{obs}}^{'}$ values are small, with the maximum angle being $0.42^\circ$ for GRB 980425, the nearest long burst observed ($z=0.0085$). The results suggest that the majority of Long GRBs are likely detected on-axis, with only a small fraction of nearby Long GRBs being observed slightly outside the jet edge.

用 123 个 Fermi-GBM 长暴标定 Amati 关系,识别出 5 个显著偏离源,并首次给出它们视角的定量约束(最大仅 0.42°),支持长暴喷流多为在轴观测。

脉络与展望

长伽马暴的 Amati 关系(E_iso–E_p,i)已被广泛用于研究喷流能量和宇宙学,而其偏离常被解释为观测视角偏离喷流轴。本文利用 123 个 Fermi-GBM 长暴重新标定这一关系,发现 5 个事件显著偏离,并通过 E_p,i–Γ 与 E_p,i–E_iso 经验相关估计出它们的视角均小于约 0.4°。这一结果支持长暴喷流张角较窄、多数事件被在轴探测的图景,但样本对邻近低能事件的偏向仍需注意。未来随着宽视场高能监视器、引力波及多信使观测的积累,对离轴长暴的比例和喷流角结构的限制有望进一步量化。

创新点在于把轨道运动、重复暴活动与偏振/色散量演化等多时标信号统一到双星起源框架,为前身星判别提供新窗口。

脉络与展望

FRB双星起源并非新概念,Wang+ 2022等已从重复暴和局域环境给出早期线索;随后的多波段与河内对应体观测不断补充语境。此次工作将FAST的多时标证据(如轨道调制、色散量长期演化、偏振位置角摆动)纳入统一双星图像,Li+ 2026Liang+ 2025Xu+ 2025等近期研究进一步提供了参数约束与场景检验。未来,长基线监测、大样本统计与引力波/多信使协同有望直接区分中子星-恒星、中子星-白矮星等具体双星通道。

采用卷积自编码器自动学习GRB特征,减少人工特征依赖,适应费米时代大样本与弱标注数据。

脉络与展望

费米时代的伽马射线暴样本规模不断扩大,传统基于经验参量的分类方法难以充分挖掘高维光变与谱信息。卷积自编码器等深度表征学习方法可以在无监督或弱监督条件下学习更具判别力的特征表示,为GRB分类提供新途径。该方法有助于减少人工特征工程的主观性,并适应大量未标注或标注噪声的数据。未来可进一步与多信使观测、实时警报和在线学习结合,提升长短暴及特殊暂现源的快速识别能力。

Scientific-Intention Driven Embodied Intelligent Solar Telescope: Conceptual Design

Lin Jiaben, Tong Liyue, Wang Hui, et al.

原文摘要Abstract

Artificial Intelligence (AI) is profoundly transforming the paradigms of scientific research. Cutting-edge technologies such as Large Language Models (LLMs) and embodied intelligence are continuously pushing the boundaries of scientific instrumentation. Against this backdrop, this paper proposes a novel conceptual system: the Scientific-Intention Driven Embodied Intelligent Solar Telescope (SIDEST). The system is designed with three core layers to achieve three types of intelligent scientific research closed loops. First, the Scientific Intent Research and Demonstration Layer parses the research objectives and intents of scientists (e.g., solar physicists) through natural language interaction, achieving a closed loop for the generation and optimization of executable observation plans aligned with scientific intent via in-depth research. Subsequently, the Observation Realization Layer schedules embodied intelligent solar telescopes to implement a closed loop for the execution of scientific observation plans. Finally, the Evaluation and Evolution Layer coordinates intelligent agents for data processing and scientific analysis to analyze observation data, generate research reports, and iteratively optimize observation strategies and model methods based on results, thereby realizing a self-evolving closed loop for the entire system. During the research process, we constructed a minimal prototype system based on a precision temperature control device for solar telescope birefringent filters to validate the core principles of SIDEST. This prototype successfully implemented all key steps of intention-driven automated research, demonstrating the feasibility of the technical pathways for the three types of intelligent research closed loops. SIDEST redefines telescopes through cutting-edge AI methods.

Reversive and Non-Reversive Magnetic CP Stars. I. Catalog

I. I. Romanyuk

原文摘要Abstract

An analysis of the distribution of signs of the longitudinal magnetic field component $B_z$ is presented for a sample of 307 chemically peculiar (CP) stars with reliably measured magnetic fields. For each star, the root-mean-square field $B_{\rm rms}$ and the extreme values of $B_z$ are used to classify the field configuration as either reversive or non-reversive. Among the 173 non-reversive stars, 100 exhibit a predominantly negative $B_z$ sign, while only 73 display a positive sign, corresponding to an excess of negative polarities by a factor of about 1.37. A subsample of stars with at least five independent measurements (254 objects) yields a similar ratio of 1.38, confirming the robustness of the asymmetry. The observed predominance of negative $B_z$ values among non-reversive CP stars in the solar neighbourhood is statistically significant. Possible origins of this asymmetry remain unclear and will be addressed in future studies.
