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…
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…
A Quarter Century of Guitar Nebula/Filament Evolution
Martijn de Vries, Roger W. Romani, Oleg Kargaltsev +6
We have collected a new deep {\it Chandra X-ray Observatory} ({\it CXO}) exposure of PSR B2224+65 and the `Guitar Nebula', mapping the complex X-ray structure. This is accompanied…
Polarized Blazar X-rays imply particle acceleration in shocks
Ioannis Liodakis, Alan P. Marscher, Iván Agudo +125
Most of the light from blazars, active galactic nuclei with jets of magnetized plasma that point nearly along the line of sight, is produced by high-energy particles, up to $\sim 1…
