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…
Overview and design optimization of a custom hybrid X-ray telescope for the International Axion Observatory (IAXO)
Yue Yu, Jooyun Woo, Ipek Altunyurt +34
We present the design optimization for maximizing the effective area of a custom X-ray optic for the International Axion Observatory (IAXO) and BabyIAXO, including its novel hybrid…
Construction and characterization of a seven-chip GridPix X-ray detector for solar axion searches
Klaus Desch, Jochen Kaminski, Christoph Krieger +2
In the scope of solar axion searches, detectors which are able to measure low energetic X-rays with high efficiency are required. For this purpose a detector based on the GridPix t…
The legacy of the IXPE instrument and prospects for the next generation of polarimetric photoelectric X-ray detectors
Hemanth Manikantan, Vladislavs Plesanovs, Paolo Soffitta +15
Imaging X-ray polarimetry with IXPE has demonstrated the scientific potential of the technique but also revealed the need for significant detector upgrades, particularly with the r…
A Proposal for the Lohengrin Experiment to Search for Dark Sector Particles at the ELSA Accelerator
Philip Bechtle, Christian Bespin, Dominique Breton +23
We present a proposal for a future light dark matter search experiment at the Electron Stretcher Accelerator ELSA in Bonn: Lohengrin. It employs the fixed-target missing momentum b…
