X-Ray Polarization from the Atoll 4U 1735-44 Suggests a Low Inclination

M. A. Díaz Teodori, A. Bobrikova, A. Gnarini +17

X-ray polarimetry is a new tool capable of probing the geometry of accretion onto weakly magnetized neutron stars. Here we present the first X-ray spectropolarimetric results from…

Discovery of Strong Energy-Dependent X-ray Polarization in the Intermediate State of GS 1354-64

Swati Ravi, Lorenzo Marra, James F. Steiner +20

We report the discovery of significant X-ray polarization from the dynamically confirmed black hole X-ray binary (BHXB) GS 1354-64 during its 2025-2026 outburst, obtained with the…

What's the Buzz About GX 13+1? Constraining Coronal Geometry with QUEEN-BEE: A Bayesian Nested Sampling Framework for X-ray Polarization Rotation Analysis

Swati Ravi, Mason Ng, Herman L. Marshall +1

Observations from the Imaging X-ray Polarimetry Explorer (IXPE) have revealed electric vector position angle (EVPA) rotation in several neutron star low-mass X-ray binaries, includ…
