活动星系核吸积盘中受阻伽马射线暴产生的高能中微子

英文原题：High-energy Neutrinos from Choked Gamma-Ray Bursts in Active Galactic Nucleus Accretion Disks

Jin-Ping Zhu, Kai Wang, Bing Zhang, Yuan-Pei Yang, Yun-Wei Yu, He Gao · 2021

为什么这项工作重要

Zhu 等人把致密 AGN 吸积盘与多信使瞬变描述连接起来。GRB 喷流在盘内停滞，反向激波加速质子，两条强子相互作用分支最终汇聚到介子衰变和高能中微子信号。

Zhu et al. connect a dense AGN accretion disk to a multi-messenger transient account. A GRB jet stalls inside the disk, its reverse shock accelerates protons, and two hadronic interaction branches converge on meson decay and a high-energy-neutrino signal.

问题

当周围物质在 GRB 喷流穿过吸积盘尺度高度之前将其阻塞时，嵌入致密 AGN 吸积盘的 GRB 喷流能否产生可探测的多信使信号？

Can a GRB jet embedded in a dense AGN accretion disk produce a detectable multi-messenger signal when the surrounding material chokes the jet before it crosses the disk scale height?

科学要点

物理描述把信使与测量分开。中微子、光子和预测的短 GRB 引力波对应体是信使；软伽马射线是一个光子波段；注量和探测器计数是可观测形式；喷流受阻和预期产额仍是模型推导的推断目标。

The Physical Account keeps the carriers and measurements separate. Neutrinos, photons, and a predicted short-GRB gravitational-wave counterpart are messengers; soft gamma rays are a photon band; fluence and detector counts are observable forms; jet choking and expected yield remain model-derived inference targets.

假设

反向激波加速的质子在盘环境中通过质子–质子和光介子通道发生相互作用。
注量和探测器计数是模型推导的输出，而不是对某个已观测事件的测量。

Reverse-shock-accelerated protons interact through proton-proton and photomeson channels in the disk environment.
Fluence and detector counts are model-derived outputs, not measurements of an observed event.

科学增量

这项工作把嵌入式喷流问题从盘内约束推进到强子相互作用分支，再到中微子、光子和短 GRB 引力波对应体的预测。它在不同研究方向中的位置属于编辑背景，不能替代科学关联。

This Work carries the embedded-jet problem from disk confinement through hadronic interaction branches to neutrino, photon, and short-GRB gravitational- wave counterpart predictions. Its cross-context placement is editorial context, not a substitute for a scientific Edge.

嵌入 AGN 吸积盘的 GRB 喷流高能中微子信号：动态喷流传播框架

Wei-Cheng Long, Yun-Wei Yu · 2026

Long 和 Yu 保留了 Zhu 等人关于嵌入式 GRB 反向激波和强子中微子的框架，同时把计算从特征停滞状态的评估扩展到完整喷流头部轨迹上的激波和冷却条件演化，并包含受阻和突破两种结果。

Long and Yu preserve Zhu et al.'s embedded-GRB reverse-shock and hadronic-neutrino scaffold while expanding the calculation from a characteristic stalling-state evaluation to evolving shock and cooling conditions along complete jet-head trajectories, including both choking and breakout outcomes.

科学陈述

claim：Dense AGN accretion-disk material can choke long- and short-GRB jets before they cross the disk scale height.
result：Reverse-shock-accelerated protons undergo proton-proton and photomeson interactions whose meson-decay products yield an all-flavor high-energy-neutrino fluence.
prediction：Choked GRBs in AGN disks may be accompanied by a neutrino burst, a cocoon shock-breakout photon signal, and for the short-GRB channel a gravitational-wave counterpart.
