The new NASA-ASI Imaging X-ray Polarimetry Explorer (IXPE) adds polarization to the traditionally measured properties (position, energy, and time) of X-ray photons. While IXPE is optimized for the 2-8 keV band, we here use calibration data and simulations to investigate potential benefits of extending the energy range to lower and to higher energies. An extended energy band may be interesting for sources emitting strongly just below 2 keV or just above 8 keV, such as blazars, isolated neutron stars, or X-ray binaries.

Abstract
The new NASA-ASI Imaging X-ray Polarimetry Explorer (IXPE) adds polarization to the traditionally measured properties (position, energy, and time) of X-ray photons. While IXPE is optimized for the 2-8 keV band, we here use calibration data and simulations to investigate potential benefits of extending the energy range to lower and to higher energies. An extended energy band may be interesting for sources emitting strongly just below 2 keV or just above 8 keV, such as blazars, isolated neutron stars, or X-ray binaries.File in questo prodotto:
