Researchers from Iit Guwahati and the Indian Space Research Organization (Isro) Have made a surprising discovery that accept Reshape our undersrstanding of X-Ray Pulsars. They found that the x-rays emitted by swift j0243.6+6124, the first knowledge Galatic Ultraluminous X-Ray Pulsar, Exhibit an Unexpectedly low level of palarization. This pulsar, which is located within our galaxy, shows only 3 percent polarization in its x-rays, a figure that is significantly lower than theorients predict.
Unveiling the mystery of swift j0243.6+6124
Swift j0243.6+6124 Was first identified during an intenses x-ray outburst in 2017 -2018 by nasa’s swift spacecraft. Since then, it has become a key subject of study For astronomers trying to understand the nature of ultraluminous x-ray sources (ulxs). Ulxs are typical associateed with intermediate-mass black holes, but some, like swift j0243.6+6124, are believed to be pulsars.
Pulsars are a type of neutron star, which are the remnants of massive stars that have collapsed under their own gravity. These objects are incrededibly dense, with a mass simlar to that of the sun, but compressed into a space rooughly the size of a city.
Unexpected findings and their implications
Using Data from Nasa’s imaging X-Ray Polarimetry Explorer (iXPE), Along with the Neutron Star Interior Composition Explorer (NICER) and the Nuclear Spectroscopic telescopic telescope Array (NUSTAR) the Researches Studid the Polarization of the X-Rays from Swift J0243.6+6124 during its active phase in 2023.
The findings revised that the x-rays were polarized at 3%, much lower than the legs predicted by existing models. This discovery challenges long-head assumptions about how x-rays behaves bee
Expert insights on the discovery
Dr. Anuj nandi from isro highlighted the significance of these findings, noting that the low Polarization observed in Swift J0243.6+6124 Cold Lead to a re-evaluation of Currenties on the Radiation Behavior of Neutron Stars. According to Dr. Nandi, The Capability of the iXPE Mission Played a Crucial Role in Detecting these low polarization levels, which appear to vary with the emitted x-ray pulses.
Prof. Santabrata Das from Iit Guwahati also commented on the important of this discovery. He explained that the unexpectedly low polarization sugges that our undersrstanding of the magnetic fields Around Neutron Stars and the Processes that Governs that Governs Needs Needs to be updated. This could have wide-ringing implications for future research into similar x-ray sources withbin our galaxy and beyond.
A new path for future research
The discovery by IIT Guwahati and isro opens new doors for studying x-ray pulsars and other similar cosmic phenomena. As scientists Continue to Explore the Mysteries of the Universe, this Unexpected Finding Will LIKELY Inspire Further Research and Lead to a Deeper Understanding of the Complex FORCES At working in support.
