Testing the Correlations between X-ray Spectral Properties and Polarization for High Synchrotron Peaked Blazars
M. Lynne Saade, Steven Ehlert, Ioannis Liodakis +4
IXPE has enabled the X-ray polarizations of many blazars to be measured. We perform the first population study for high synchrotron peaked blazars observed using IXPE using a unifo…
Hard X-ray Sources in Fermi UFOs
Alessandro Paggi, Ioannis Liodakis, John Antoniadis +7
Identification and/or association of unidentified -ray sources with lower-energy counterparts represents a key challenge in modern astronomy, due to the relatively large positi…
X-Ray Polarization from the Gamma-Ray Binary LS I +61 303
Philip Kaaret, Sudip Chakraborty, Daniel Golonka +5
The gamma-ray emitting binary stellar system LS I +61 303 was observed with the Imaging X-ray Polarimetry Explorer (IXPE) on two successive orbits over orbital phases of 0.74 to 1.…
The IXPE and multifrequency polarimetric view of the extreme blazars 1ES 1101-232 and RGB J0710+591
Fabrizio Tavecchio, Dawoon E. Kim, Gabriel Emery +53
Multiwavelength polarimetry is a powerful tool to probe magnetic field and flow geometries in the relativistic jets of blazars. In this respect, particularly interesting are the so…
Where within the 3C 84 jet are -rays produced?
Georgios F. Paraschos, Ioannis Liodakis, Svetlana Jorstad +49
The location of -ray creation and emission within extra-galactic jets is a matter of active debate. One particularly well-suited source to pinpoint the location is the nearby,…
Magnetic-field Order in the Southwestern Rim of RCW 86 Constrained Using X-Ray Polarimetry
Stefano Silvestri, Dmitry Prokhorov, Jacco Vink +97
RCW 86 is a supernova remnant whose origin has recently been linked to an off-center explosion within a cavity created by its progenitor star. In the southwestern region, the forwa…
