From Stellar Death to Cosmic Revelations: Zooming in on Compact Objects, Relativistic Outflows and Supernova Remnants with AXIS
S. Safi-Harb, K. B. Burdge, A. Bodaghee +32
Compact objects and supernova remnants provide nearby laboratories to probe the fate of stars after they die, and the way they impact, and are impacted by, their surrounding medium…
IXPE observation confirms a high spin in the accreting black hole 4U 1957+115
L. Marra, M. Brigitte, N. Rodriguez Cavero +113
We present the results of the first X-ray polarimetric observation of the low-mass X-ray binary 4U 1957+115, performed with the Imaging X-ray Polarimetry Explorer in May 2023. The…
X-ray polarimetry and spectroscopy of the neutron star low-mass X-ray binary GX 9+9: an in-depth study with IXPE and NuSTAR
F. Ursini, R. Farinelli, A. Gnarini +101
We report on a comprehensive analysis of simultaneous X-ray polarimetric and spectral data of the bright atoll source GX 9+9 with the Imaging X-ray Polarimetry Explorer (IXPE) and…
The geometry of the hot corona in MCG-05-23-16 constrained by X-ray polarimetry
D. Tagliacozzo, A. Marinucci, F. Ursini +105
We report on the second observation of the radio-quiet active galactic nucleus (AGN) MCG-05-23-16 performed with the Imaging X-ray Polarimetry Explorer (IXPE). The observation star…
The X-ray polarisation of the Seyfert 1 galaxy IC 4329A
A. Ingram, M. Ewing, A. Marinucci +105
We present an X-ray spectro-polarimetric analysis of the bright Seyfert galaxy IC 4329A. The Imaging X-ray Polarimetry Explorer (IXPE) observed the source for ~500 ks, supported by…
X-ray polarimetry of X-ray pulsar X Persei: another orthogonal rotator?
A. A. Mushtukov, S. S. Tsygankov, J. Poutanen +103
X Persei is a persistent low-luminosity X-ray pulsar of period of 835 s in a Be binary system. The field strength at the neutron star surface is not known precisely, but indi…
