X-ray and multiwavelength polarization of Mrk 501 from 2022 to 2023

Chien-Ting J. Chen, Ioannis Liodakis, Riccardo Middei +143

We present multiwavelength polarization measurements of the luminous blazar Mrk~501 over a 14-month period. The 2--8 keV X-ray polarization was measured with the Imaging X-ray Pola…

An IXPE-Led X-ray Spectro-Polarimetric Campaign on the Soft State of Cygnus X-1: X-ray Polarimetric Evidence for Strong Gravitational Lensing

James F. Steiner, Edward Nathan, Kun Hu +134

We present the first X-ray spectropolarimetric results for Cygnus X-1 in its soft state from a campaign of five IXPE observations conducted during 2023 May-June. Companion multiwav…

Investigating the Properties of the Relativistic Jet and Hot Corona in AGN with X-ray Polarimetry

Dawoon E. Kim, Laura Di Gesu, Frédéric Marin +6

X-ray polarimetry has been suggested as a prominent tool for investigating the geometrical and physical properties of the emissions from active galactic nuclei (AGN). The successfu…

The outflowing ionised gas of I Zw 1 observed by HST COS

A. Juráňová, E. Costantini, G. A. Kriss +8

We present an analysis of the HST COS spectrum of IZw1 aiming to probe the absorbing medium associated with the active galactic nucleus (AGN). We fitted the emission spectrum and p…

Discovery of a strong rotation of the X-ray polarization angle in the galactic burster GX 13+1

Anna Bobrikova, Sofia V. Forsblom, Alessandro Di Marco +106

Weakly magnetized neutron stars in X-ray binaries show complex phenomenology with several spectral components that can be associated with the accretion disk, boundary and/or spread…
