The Imaging X-Ray Polarimetry Explorer (IXPE): Pre-Launch
Martin C. Weisskopf, Paolo Soffitta, Luca Baldini +155
Scheduled to launch in late 2021, the Imaging X-ray Polarimetry Explorer (IXPE) is a NASA Small Explorer Mission in collaboration with the Italian Space Agency (ASI). The mission w…
Probing Particle Acceleration through Gamma-ray Solar Flare Observations
Melissa Pesce-Rollins, Nicola Omodei, Vahe' Petrosian +1
High-energy solar flares have shown to have at least two distinct phases: prompt-impulsive and delayed-gradual. Identifying the mechanism responsible for accelerating the electrons…
Prospects for the polarimetric mapping of the Sgr A molecular cloud complex with IXPE
Riccardo Ferrazzoli, Laura Di Gesu, Immacolata Donnarumma +5
The X-ray polarization degree of the molecular clouds that surround Sgr A* is expected to be greatly lowered because the polarized reflection emission is mixed with the unpolarized…
Exploring the accretion-ejection geometry of GRS 1915+105 in the obscured state with future X-ray spectro-polarimetry
Ajay Ratheesh, Giorgio Matt, Francesco Tombesi +3
GRS 1915+105 has been in a bright flux state for more than 2 decades, but in 2018 a significant drop in flux was observed, partly due to changes in the central engine along with in…
The Instrument of the Imaging X-ray Polarimetry Explorer
Paolo Soffitta, Luca Baldini, Ronaldo Bellazzini +78
While X-ray Spectroscopy, Timing and Imaging have improved verymuch since 1962, when the first astronomical non-solar source was discovered, especially with the launch of Newton/X-…
Design, Construction, and Test of the Gas Pixel Detectors for the IXPE Mission
L. Baldini, M. Barbanera, R. Bellazzini +91
Due to be launched in late 2021, the Imaging X-Ray Polarimetry Explorer (IXPE) is a NASA Small Explorer mission designed to perform polarization measurements in the 2-8 keV band, c…
