Description
The Imaging X-ray Polarimetry Explorer (IXPE), scheduled for launch in Fall 2021, will open up the window of X-ray polarimetry. IXPE will be joined by XL-Calibur in 2022, adding 15-75 keV polarimetric capabilities to IXPE’s 2-8 keV coverage.The exciting science topics that can be addressed with IXPE include observations of stellar mass black holes and observations of magnetars. I will report here on the IXPE and XL-Calibur observation programs of these two source classes, the models that havebeen developed to analyze the data. and results from fitting archival spectroscopic observations with these models. Last but not least,. I will discuss simulated IXPE and XL-Calibur observations, and discuss the scientific questions that we expect to be ableto answer with these observations.
