Development of Solar Flare X-ray Polarimeter with Micro-Pixel CMOS Sensors

Kouichi Hagino, Tatsuaki Kato, Toshiya Iwata +10

We are developing an X-ray polarimeter using micro-pixel CMOS sensors for solar flare X-ray polarimetry. The system consists of a 2.5- $μ$ m pixel CMOS image sensor with a 12.8$\time…

XRISM analysis of the complex Fe K $α$ line in Centaurus A

David Bogensberger, Yuya Nakatani, Tahir Yaqoob +14

We analyze the high-resolution XRISM/Resolve spectrum of the Fe K $α$ emission line of the nearest active galactic nucleus, in Centaurus A. The line features two narrow and resolved…
