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 First X-ray Polarization Observation of the Black Hole X-ray Binary 4U 1630-47 in the Steep Power Law State
Nicole Rodriguez Cavero, Lorenzo Marra, Henric Krawczynski +107
The Imaging X-ray Polarimetry Explorer (IXPE) observed the black hole X-ray binary 4U 1630-47 in the steep power law (or very high) state. The observations reveal a linear polariza…
Vela pulsar wind nebula x-rays are polarized to near the synchrotron limit
Fei Xie, Alessandro Di Marco, Fabio La Monaca +90
Pulsar wind nebulae are formed when outflows of relativistic electrons and positrons hit the surrounding supernova remnant or interstellar medium at a shock front. The Vela pulsar…
IXPE observations of the quintessential wind-accreting X-ray pulsar Vela X-1
Sofia V. Forsblom, Juri Poutanen, Sergey S. Tsygankov +97
The radiation from accreting X-ray pulsars was expected to be highly polarized, with some estimates for the polarization degree of up to 80%. However, phase-resolved and energy-res…
The IXPE view of GRB 221009A
Michela Negro, Niccoló Di Lalla, Nicola Omodei +108
We present the IXPE observation of GRB 221009A which includes upper limits on the linear polarization degree of both prompt and afterglow emission in the soft X-ray energy band. GR…
A strong X-ray polarization signal from the magnetar 1RXS J170849.0-400910
Silvia Zane, Roberto Taverna, Denis Gonzalez Caniulef +99
Magnetars are the most strongly magnetized neutron stars, and one of the most promising targets for X-ray polarimetric measurements. We present here the first Imaging X-ray Polarim…
