Results of X-ray polarimetry with the Imaging X-ray Polarimetry Explorer (IXPE) of Galactic sources such as magnetars, pulsing neutron stars, and stellar mass black holes in binary system

After nearly five decades from the flight of OSO-8 and the first detection of polarized X-rays from the Crab, we just entered the era of X-ray polarimetry, with the launch of the Imaging X-ray Polarimetry Explorer in December of 2021. Because of its sensitivity to the geometry of the sources and to magnetic field structures, X-ray polarimetry now allows us to study compact objects in a completely new way, and the first year of operation for IXPE has been full of exciting results for Galactic science. In my talk, I will present some of the first results on Galactic sources, from magnetars, to pulsar wind nebulae, to X-ray binaries.
