Title: Relativistic jets in the discovery era of X-ray polarimetry
Abstract:

X-ray polarization is a crucial probe of the magnetic field structure and emission processes in astrophysical systems. This is particularly true for relativistic jets from supermassive black holes, where polarimetry allows us to investigate their composition and particle acceleration mechanisms. Until now, polarization observations have been limited to the radio-to-optical range, thereby leaving a gap in our understanding of the processes and physical conditions in the most energetic objects in the Universe. The recently launched Imaging X-ray Polarimetry Explorer (IXPE), NASA's very first X-ray polarization mission, offers a radical new way of studying high-energy processes in these jets. I will discuss the multiwavelength polarization observations and results from the first year of IXPE observations of radio galaxies and blazars.
