Polarization properties of the weakly magnetized neutron star X-ray binary GS 1826-238 in the high soft state

Fiamma Capitanio, Sergio Fabiani, Andrea Gnarini +94

The launch of the Imaging X-ray Polarimetry Explorer (IXPE) on 2021 December 9 has opened a new window in X-ray astronomy. We report here the results of the first IXPE observation…

X-ray Polarization Observations of BL Lacertae

Riccardo Middei, Ioannis Liodakis, Matteo Perri +143

Blazars are a class of jet-dominated active galactic nuclei with a typical double-humped spectral energy distribution. It is of common consensus the Synchrotron emission to be resp…

Explaining the moderate UV/X-ray correlation in AGN

Christos Panagiotou, Erin Kara, Michal Dovčiak

The UV/optical and X-ray variability of active galactic nuclei (AGN) have long been expected to be well correlated as a result of the X-ray illumination of the accretion disk. Rece…

Observations of 4U 1626-67 with the Imaging X-ray Polarimetry Explorer

Herman L. Marshall, Mason Ng, Daniele Rogantini +91

We present measurements of the polarization of X-rays in the 2-8 keV band from the pulsar in the ultracompact low mass X-ray binary 4U1626-67 using data from the Imaging X-ray Pola…

The X-ray Polarization View of Mrk~421 in an Average Flux State as Observed by the Imaging X-ray Polarimetry Explorer

Laura Di Gesu, Immacolata Donnarumma, Fabrizio Tavecchio +100

Particle acceleration mechanisms in supermassive black hole jets, such as shock acceleration, magnetic reconnection, and turbulence, are expected to have observable signatures in t…

The X-ray polarimetry view of the accreting pulsar Cen X-3

Sergey S. Tsygankov, Victor Doroshenko, Juri Poutanen +95

Cen X-3 is the first X-ray pulsar discovered 50 years ago. Radiation from such objects is expected to be highly polarized due to birefringence of plasma and vacuum associated with…
