X-ray polarimetry on-board HXMT
Paolo Soffitta, Ronaldo Bellazzini, Gianpiero Tagliaferri +15
The development of micropixel gas detectors, capable to image tracks produced in a gas by photoelectrons, makes possible to perform polarimetry of X-ray celestial sources in the fo…
XPOL: a photoelectric polarimeter onboard XEUS
Enrico Costa, Ronaldo Bellazzini, Jean Bregeon +14
The XEUS mission incorporates two satellites: the Mirror Spacecraft with 5 m2 of collecting area at 1 keV and 2 m2 at 7 keV, and an imaging resolution of 5" HEW and the Payload Spa…
The Gas Pixel Detector as an X-ray photoelectric polarimeter with a large field of view
Fabio Muleri, Paolo Soffitta, Ronaldo Bellazzini +9
The Gas Pixel Detector (GPD) is a new generation device which, thanks to its 50 um pixels, is capable of imaging the photoelectrons tracks produced by photoelectric absorption in a…
A versatile facility for the calibration of X-ray polarimeters with polarized and unpolarized controlled beams
Fabio Muleri, Paolo Soffitta, Ronaldo Bellazzini +8
We devised and built a versatile facility for the calibration of the next generation X-ray polarimeters with unpolarized and polarized radiation. The former is produced at 5.9 keV…
Thermal disc emission from a rotating black hole: X-ray polarization signatures
M. Dovciak, F. Muleri, R. W. Goosmann +2
Thermal emission from the accretion disc around a black hole can be polarized, due to Thomson scattering in a disc atmosphere. In Newtonian space, the polarization angle must be ei…
