X-ray polarization detection of Cassiopeia A with IXPE
And now the first Imaging polarimetry result from IXPE!
Jakko Vink has just published an ApJ paper describing first infant steps towards the true spatially-resolved analysis of supernova remnants.
We're still talking about two sigma detection in individual pixels, but overall significance is of course much higher. And that's the first time X-ray polarimetry was used to probe magnetic field structure in an SNR!
Observed polarization appears to be in line with what radio (still bringing some new insights), which is also a good thing!
