脉冲星风星云、耀变体、伽马射线爆发和磁星都包含电磁能量密度大大超过等离子体能量密度的区域。这些源表现出剧烈的耀斑活动，其中电磁能分布在大体积上，似乎被有效地转化为高能粒子和射线。我们将这种一般过程称为磁致发光。描述了对潜在的极端粒子加速过程的全球要求，并强调了相对论射束在增强观测到的耀斑辐射方面可能的重要性。总结了最近关于不稳定电磁配置的流体描述的研究，并讨论了解释加速度和辐射所需的相关动力学模拟的进展。简要总结了未来的观察、模拟和实验机会。
Pulsar Wind Nebulae, Blazars, Gamma Ray Bursts and Magnetars all contain regions where the electromagnetic energy density greatly exceeds the plasma energy density. These sources exhibit dramatic flaring activity where the electromagnetic energy distributed over large volumes, appears to be converted efficiently into high energy particles and-rays. We call this general process magnetoluminescence. Global requirements on the underlying, extreme particle acceleration processes are described and the likely importance of relativistic beaming in enhancing the observed radiation from a flare is emphasized. Recent research on fluid descriptions of unstable electromagnetic configurations are summarized and progress on the associated kinetic simulations that are needed to account for the acceleration and radiation is discussed. Future observational, simulation and experimental opportunities are briefly summarized.
