Simultaneous space and phase resolved X-ray polarimetry of the Crab Pulsar and Nebula

Understand

The Crab pulsar and its nebula are among the most studied astrophysical systems, and constitute one of the most promising environments where high energy processes and particle acceleration can be investigated.

• They are the only objects for which previous X-ray polarisation has been reported.
• We present here the first Imaging X-ray Polarimetry Explorer (IXPE) observation of the Crab pulsar and nebula.
• The total pulsar pulsed emission in the [2-8] keV energy range is unpolarised.
