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…
Low energy polarization sensitivity of the Gas Pixel Detector
F. Muleri, P. Soffitta, L. Baldini +15
An X-ray photoelectric polarimeter based on the Gas Pixel Detector has been proposed to be included in many upcoming space missions to fill the gap of about 30 years from the first…
