Polarization constraints on the X-ray corona in Seyfert Galaxies: MCG-05-23-16

And another IXPE paper! This time on Seyfert galaxy MCG-05-23-16. We report on the first observation of a radio-quiet Active Galactic Nucleus (AGN) using polarized X-rays. Half a megasecond of IXPE time plus some XMM and NuSTAR. Only an upper limit on the polarization, but that's valuable as low polarization might indicate a lamp-post and a conical geometry of the corona (and if it's a slab, then some rather strict constrains on inclination must be satisfied). Stay tuned for more IXPE papers!
