Refined Constraints on the Hard X-ray Polarization of the Crab Pulsar and Nebula Derived from an Extended XL-Calibur Dataset

Matthew G. Baring, Jacob Casey, Sohee Chun +26

We present updated hard X-ray polarization measurements of the Crab pulsar and nebula obtained with the balloon-borne polarimeter XL-Calibur in the ~19-64 keV energy range. During…

XL-Calibur measurements of polarised hard X-ray emission from the Crab

Hisamitsu Awaki, Matthew G. Baring, Richard Bose +46

We report measurements of the linear polarisation degree (PD) and angle (PA) for hard X-ray emission from the Crab pulsar and wind nebula. Measurements were made with the XL-Calibu…
