EXPO: a quantum leap in fast, wide-band X-ray polarimetry for astrophysics
Paolo Soffitta, Sebastien Guillot, Ian Hutchinson +137
The Enhanced X-ray Polarimetry Observatory (EXPO) is a mission concept proposed to ESA as an M8 candidate, with a prospective launch in 2041. Building on the scientific success of…
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…
Instruments for Focal Plane X-Ray Polarimetry in the Next Decade
Fabio Muleri, Stefano Cesare, Enrico Costa +18
The successful detection of X-ray polarization from many celestial sources belonging to different classes by the IXPE mission has opened a new window in X-ray astronomy. While an i…
Graph Neural Networks Trained on Null Signal for Angle Reconstruction in X-ray Polarimetry
Vittorio Latorre, Victor Rodriguez-Fernandez, Alessandro Di Marco +3
Scientific real detectors often produce sparse, irregular data defined on non-Euclidean domains, where conventional convolutional neural networks (CNNs) impose geometric biases tha…
In-flight performance of the IXPE telescopes
Riccardo Ferrazzoli, Enrico Costa, Sergio Fabiani +15
We present a comprehensive characterization of the on-orbit imaging performance of the three telescopes on board the Imaging X-ray Polarimetry Explorer (IXPE). Each telescope compr…
Towards imaging-spectro-polarimetry of solar flares in the X-rays
Sergio Fabiani, John Rankin, Stefano Basso +19
X-ray polarimetry of solar flares is still a not well established field of observation of our star. Past polarimeters were not able to measure with a high significance the polariza…
