Observations inspect X-ray radiation from Vela X-1

Using the Imaging X-ray Polarimetry Explorer (IXPE), an international team of astronomers has conducted X-ray polarimetric observations of an accreting X-ray pulsar known as Vela X-1. Results of the observational campaign, presented March 3 on the arXiv pre-print server, deliver important insights into the properties of X-ray radiation from this pulsar.
