One of the most fascinating astrophysical phenomena to study are powerful flares of photon and particle radiation from cosmic events. These are often triggered by the sudden release of a large quantity of energy during a catastrophic event. Particular spectacular is the release of enormous amounts of energy on second-to-minutes timescales in the cosmologically distant sources of gamma ray bursts and active galactic nuclei associated with relativistic outflows.It is proposed to investigate two major, closely interlinked research topics:(A) Modelling proton and electron intensities and anisotropies from large solar flare events,(B) Synchrotron-Self Compton (SSC) flaring of active galactic nuclei.In both subprojects it is necessary to solve time-dependent transport equations of energetic hadrons and electrons which although in different cosmic environments have the same mathematical structure. The radiation modelling in SSC emission models additionally requires the inclusion of propagation and retardation effects of the generated nonthermal photons.

最令人着迷的天体物理现象之一是来自宇宙事件的光子和粒子辐射的强大耀斑。这些通常是由灾难性事件中大量能量的突然释放引发的。特别壮观的是，在宇宙遥远的伽马射线爆发源和与相对论性外流有关的活动星系核中，以秒到分钟的时间尺度释放出大量能量。建议研究两个主要的，密切相关的研究课题：(A)模拟大型太阳耀斑事件的质子和电子强度和各向异性，(B)活动星系核的同步自康普顿（SSC）耀斑。在这两个子项目中，有必要求解高能强子和电子的随时间的输运方程，尽管它们在不同的宇宙环境中具有相同的数学结构。SSC发射模型中的辐射建模还需要包含产生的非热光子的传播和延迟效应。
