ISRO has successfully launched the satellite XPoSat which is world’s second ‘X-ray Polarimetry Космос Observatory’. This will carry out research in пространство-based polarisation measurements of X-ray emission from various cosmic sources. Earlier, НАСА had sent ‘Imaging X-ray Polarimetry Explorer (IXPE)’ into пространство in 2021 for the same objectives. X-ray Polarimetry Космос Observatories measure the amount and direction of polarization of incoming X-rays emanating from cosmic bodies and служи като уникален инструмент за изучаване на законите на природата в екстремни условия.
индийски Космос Research Organisation (ISRO) has successfully launched XPoSat, a ‘X-ray Polarimetry Observatory’. It is designed to carry out research in пространство-based polarisation and spectroscopic measurements of X-ray emission from cosmic sources.
Той носи два полезни товара, а именно POLIX (полариметърен инструмент в рентгенови лъчи) и XSPECT (рентгенова спектроскопия и синхронизация). Докато POLIX ще измерва поляризацията на рентгеновите лъчи в енергийната лента 8-30keV, излъчвана от около 50 потенциални космически източника чрез Thomson Scattering, полезният товар XSPECT ще извършва дългосрочни спектрални и времеви изследвания на космически рентгенови източници в енергийна лента 0.8 -15ке.
НАСА Imaging X-ray Polarimetry Explorer (IXPE) launched into пространство on 9 December 2021 was the first X-ray Polarimetry Космос 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 черни дупкиИ др
X-ray Polarimetry Космос 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 Космос Observatories like IXPE and XPoSat serve as a unique tool to study the laws of nature in extreme conditions.
