A Focal-plane X-ray Polarimeter with Spectral and Timing Capabilities for Future Missions
Hemanth Manikantan, Carlo Lefevre, Lorenzo Petrucci +16
The NASA-ASI mission Imaging X-ray Polarimeter Explorer (IXPE) firmly established X-ray polarimetry as a core observation pillar of high-energy astrophysics, alongside imaging, tim…
Peering through the dip: IXPE unveils the extended scattering environment of GX 13+1
Alessandro Di Marco, Fabio La Monaca, Luigi Stella +17
Neutron star low-mass X-ray binaries feature complex accretion geometries, often including an accretion disk corona or disk winds. Here, a study of the highly inclined dipping sour…
Unchanged X-Ray Polarization During Accretion Dips in the Low Hard State of Cygnus X-1
Yu-shan Ling, Fei Xie, Alessandro Di Marco +2
The study examines X-ray polarization of the black‑hole binary Cygnus X-1 during flux‑decrease events in its low‑hard state and finds that the polarization degree and angle remain…
The hitchhiker's guide to the IXPE data analysis
Alessandro Di Marco
The chapter offers a practical guide to analyzing data from the Imaging X-ray Polarimetry Explorer (IXPE), covering instrument basics, data formats, processing steps, and methods t…
Pulse profile modelling of the 2024 outburst of the accreting millisecond pulsar SRGA J144459.2-604207
Bas Dorsman, Tuomo Salmi, Anna L. Watts +14
Pulse profile modelling via relativistic ray-tracing can constrain the system parameters of neutron stars, notably their mass and radius. Among these objects, accreting millisecond…
A deep X-ray and UV look into the reflaring stage of the accreting millisecond pulsar SAX J1808.4-3658
Caterina Ballocco, Alessandro Papitto, Arianna Miraval Zanon +12
We present an X-ray and UV high-time-resolution monitoring of the final flaring phase of the 2022 outburst of the AMSP SAX J1808.4-3658, based on simultaneous XMM-Newton and HST ob…
