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…
AGILE detection of intense gamma-ray emission from the blazar PKS 1510-089
G. Pucella, V. Vittorini, F. D'Ammando +59
We report the detection by the AGILE (Astro-rivelatore Gamma a Immagini LEggero) satellite of an intense gamma-ray flare from the source AGL J1511-0909, associated with the powerfu…
Multiwavelength observations of 3C 454.3. I. The AGILE 2007 November campaign on the "Crazy Diamond"
S. Vercellone, A. W. Chen, V. Vittorini +68
[Abridged] We report on a multiwavelength observation of the blazar 3C 454.3 (which we dubbed "crazy diamond") carried out on November 2007 by means of the astrophysical satellites…
