X-ray Polarimetry of Supernova Remnants

, 2021
Young supernova remnants such as Tycho, Cas A and SN1006 are relativistic particle accelerators and likely the sources of Galactic cosmic rays. In these sources X-ray synchrotron emitting regions, such as the shock fronts, have been identified and their ...

The IXPE View of Neutron Star Low-Mass X-ray Binaries

Galaxies
Low-mass X-ray binaries hosting weakly magnetized neutron stars (NS-LMXBs) are among the brightest sources in the X-ray sky. Since 2021, the Imaging X-ray Polarimetry Explorer (IXPE) has provided new measurements of the X-ray polarization of these ...
