Discovery of energy-dependent phase variations in the polarization angle of Cen X-3
Qing-Chang Zhao, Lian Tao, Sergey S. Tsygankov +7
We present a detailed polarimetric analysis of Cen X-3 using \ixpe observations during its high state, revealing complex energy-dependent polarization behavior. While phase-average…
POLAR-2 -- Latest Developments of the Next Generation GRB Polarimeter
Johannes Hulsman, Philipp Azzarello, Joerg Bayer +20
Gamma-Ray Bursts (GRBs) are among the most energetic events in the Universe. Despite over 50 years of research and measurements their prompt emission remains poorly understood, wit…
Gamma-Ray Burst Polarimetry with the POLAR and POLAR-2 missions
Nicolas De Angelis, Philipp Azzarello, Franck Cadoux +15
Gamma-Ray Bursts are among the most powerful and violent events in the Universe. Despite over half a century of observations of these transient sources, many open questions remain…
Design and Performance of a Universal SiPM Readout System for X- and Gamma-Ray Missions
Merlin Kole, Nicolas De Angelis, Nicolas Produit +15
The advent of both multi-messenger and time-domain astrophysics over the last decade has seen a large interest in the development of small-scale, cheap, and robust gamma-ray detect…
