XPoSat : ISRO が世界 2 番目の「X 線偏光計宇宙観測所」を打ち上げ

ISRO has successfully launched the satellite XPoSat which is world’s second ‘X-ray Polarimetry スペース Observatory’. This will carry out research in スペース-based polarisation measurements of X-ray emission from various cosmic sources. Earlier, 米航空宇宙局（NASA） had sent ‘Imaging X-ray Polarimetry Explorer (IXPE)’ into スペース in 2021 for the same objectives. X-ray Polarimetry スペース Observatories measure the amount and direction of polarization of incoming X-rays emanating from cosmic bodies and 極限状態における自然法則を研究するためのユニークなツールとして機能します。

インディアンスペース Research Organisation (ISRO) has successfully launched XPoSat, a ‘X-ray Polarimetry Observatory’. It is designed to carry out research in スペース-based polarisation and spectroscopic measurements of X-ray emission from cosmic sources.

これは、POLIX (X 線偏光計装置) と XSPECT (X 線分光法およびタイミング) という 8 つのペイロードを搭載しています。 POLIXはトムソン散乱を通じて約30の潜在的な宇宙線源から発せられるエネルギー帯50～0.8keVのX線の偏光を測定する一方、XSPECTペイロードはエネルギー帯15の宇宙X線源の長期スペクトル研究と時間研究を実行します。 -XNUMXケ。

NASAの Imaging X-ray Polarimetry Explorer (IXPE) launched into スペース on 9 December 2021 was the first X-ray Polarimetry スペース Observatory. Since its launch, it has contributed to several groundbreaking research through studying polarization of X-rays from many different types of celestial objects such as the remnants of supernova explosions, powerful particle streams spit out by feeding ブラックホール, etc.

X-ray Polarimetry スペース Observatories measure the amount and direction of polarization of incoming X-rays emanating from cosmic bodies.

Since polarised light carries unique details about the source and medium it has passed through, X-ray Polarimetry スペース Observatories like IXPE and XPoSat serve as a unique tool to study the laws of nature in extreme conditions.
