NASA's IXPE helps solve black hole jet mystery NASAGoddard nature
NASA's Imaging X-Ray Polarimetry Explorer, or IXPE, has helped astronomers get closer to an answer. In a new study in the journal, authored by a large international collaboration, astronomers find that the best explanation for the particle acceleration is a shock wave within the jet.
"The first X-ray polarization measurements of this class of sources allowed, for the first time, a direct comparison with the models developed from observing other frequencies of light, from radio to very high-energy gamma rays," said Immacolata Donnarumma, the project scientist for IXPE at the Italian Space Agency."IXPE will continue to provide new evidence as the current data is analyzed and additional data is acquired in the future.
"Adding X-ray polarization to our arsenal of radio, infrared, and optical polarization is a game changer," said Alan Marscher, an astronomer at Boston University who leads the group studying giant black holes with IXPE.
