Imaging X-ray Polarimetry Explorer
Launched: December 9, 2021
Overview
IXPE is designed to observe the polarization of X-rays from extreme objects like black holes and neutron stars. This technique offers unique insights into the physics of these objects that cannot be obtained from other types of observations.
Primary Objectives
- Measure the polarization of X-rays from various cosmic sources
- Explore the geometry and physics of black holes and neutron stars
- Study the origins of cosmic X-rays
- Investigate magnetic fields in cosmic objects
Notable Discoveries
- First detailed polarization measurements of supernova remnant Cassiopeia A
- Provided new insights into the structure of magnetic fields in pulsars
- Revealed hidden details about the environment around black holes
- Measured polarization in active galactic nuclei
