Description

We present the first X-ray polarimetric measurements of three Seyfert 1 galaxies with IXPE, the NASA/ASI mission operating as of December 2021. The results allow us to directly constrain the geometrical shape of the hot corona for the first time. We discuss the implications for the physical interpretation of X-ray variability in these sources.
