Discovery of X-ray polarization angle rotation in active galaxy Mrk 421
Laura Di Gesu, Herman L. Marshall, Steven R. Ehlert +140
The magnetic field conditions in astrophysical relativistic jets can be probed by multiwavelength polarimetry, which has been recently extended to X-rays. For example, one can trac…
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…
Uncovering the geometry of the hot X-ray corona in the Seyfert galaxy NGC4151 with IXPE
V. E. Gianolli, D. E. Kim, S. Bianchi +106
We present an X-ray spectro-polarimetric analysis of the bright Seyfert galaxy NGC4151. The source has been observed with the Imaging X-ray Polarimetry Explorer (IXPE) for 700 ks,…
Handling Background in IXPE polarimetric data
Alessandro Di Marco, Paolo Soffitta, Enrico Costa +18
IXPE (Imaging X-ray Polarimetry Explorer) is a Small Explorer mission by NASA and ASI, launched on December 9 2021, dedicated to investigating X-ray polarimetry allowing ang…
