Fall 2022 Physics Colloquium:- Imaging X-ray Polarimetry Explorer(IXPE): The Mission, Initial Discoveries and Future Prospects
IXPE, launched on December 9, 2021, is the first mission devoted to polarimetry of celestial targets in the classical soft X-ray band. Some 50 years after the first (and until recently, only) X-ray polarimetry detection(measuring the Crab nebula), IXPE has increased our polarization sensitivity by a factor of 100x and provided the first imaging polarimetry studies. With over 25 sources observed to date, from a dozen source classes, IXPE is establishing polarimetry as a powerful tool to explore the physics of compact objects and their outflows. After a review of IXPE’s instrumentation and comment on the prospects for improved polarization analysis, the speaker and his team summarize some recent discoveries and outline the opportunities for additional work in the upcoming Guest Observer phase of the project.
