X-ray polarization observations of IC 4329A with IXPE: Constraining the geometry of the X-ray corona
X-ray polarimetry is a powerful tool to probe the geometry of the hot X-ray corona in active galactic nuclei (AGN). Here, we present our results on the characterisation of the X-ray polarization of the radio-quiet Seyfert-type AGN IC 4329A…
