星暴星系M82和NGC3256的电荷交换辐射

Charge-exchange emission in the starburst galaxies M82 and NGC3256

Piero Ranalli

摘要:

电荷交换(CE)发射产生的功能,这是检测与当前的X射线仪器在最明亮的近星系。我们描述了这些方面的恒星形成星系M82和NGC 3256,从朱雀和XMM-牛顿望远镜观测到的X射线光谱。从离子(O,C)和中性(Mg,Si)的发射是公认的。我们还描述了如何在未来的任务微量热计仪器将改善CE观测。

英文摘要:

Charge-exchange (CE) emission produces features which are detectable with the current X-ray instrumentation in the brightest near galaxies. We describe these aspects in the observed X-ray spectra of the star forming galaxies M82 and NGC 3256, from the Suzaku and XMM-Newton telescopes. Emission from both ions (O, C) and neutrals (Mg, Si) is recognised. We also describe how microcalorimeter instrumentation on future missions will improve CE observations.
