Analysis of Crab X-ray Polarization using Deeper IXPE Observations
Analysis of Crab X-ray Polarization using Deeper IXPE Observations
We present Crab X-ray polarization measurements using IXPE data with a total exposure of 300ks, three times more than the initial 2022 discovery paper. Polarization is detected in three times more pulsar phase bins, revealing an S-shaped $+40^\circ$ polarization angle sweep in the main pulse and ${>}1\sigma$ departures from the …
