PoGO+ polarimetric constraint on the synchrotron jet emission of Cygnus X-1
Maxime Chauvin, Hans-Gustav Florén, Miranda Jackson +8
We report a polarimetric constraint on the hard X-ray synchrotron jet emission from the Cygnus X-1 black-hole binary system. The observational data were obtained using the PoGO+ ha…
The PoGO+ view on Crab off-pulse hard X-ray polarisation
M. Chauvin, H. -G. Florén, M. Friis +11
The linear polarisation fraction and angle of the hard X-ray emission from the Crab provide unique insight into high energy radiation mechanisms, complementing the usual imaging, t…
Shedding new light on the Crab with polarized X-rays
M. Chauvin, H. -G. Florén, M. Friis +13
Strong magnetic fields, synchrotron emission, and Compton scattering are omnipresent in compact celestial X-ray sources. Emissions in the X-ray energy band are consequently expecte…
Optimising a balloon-borne polarimeter in the hard X-ray domain: from the PoGOLite Pathfinder to PoGO+
Maxime Chauvin, Miranda Jackson, Takafumi Kawano +6
PoGOLite is a balloon-borne hard X-ray polarimeter dedicated to the study of point sources. Compton scattered events are registered using an array of plastic scintillator units to…
Preflight performance studies of the PoGOLite hard X-ray polarimeter
M. Chauvin, M. Jackson, T. Kawano +6
Polarimetric studies of astrophysical sources can make important contributions to resolve the geometry of the emitting region and determine the photon emission mechanism. PoGOLite…
PoGOLino: a scintillator-based balloon-borne neutron detector
Merlin Kole, Maxime Chauvin, Yasushi Fukazawa +12
PoGOLino is a balloon-borne scintillator-based experiment developed to study the largely unexplored high altitude neutron environment at high geomagnetic latitudes. The instrument…
INTEGRAL/SPI data segmentation to retrieve source intensity variations
L. Bouchet, P. -R Amestoy, A. Buttari +2
The INTEGRAL/SPI, X-gamma-ray spectrometer (20 keV - 8 MeV) is an instrument for which recovering source intensity variations is not straightforward and can constitute a difficulty…
Simultaneous analysis of large INTEGRAL/SPI datasets: optimizing the computation of the solution and its variance using sparse matrix algorithms
L. Bouchet, P. Amestoy, A. Buttari +2
Nowadays, analyzing and reducing the ever larger astronomical datasets is becoming a crucial challenge, especially for long cumulated observation times. The INTEGRAL/SPI X-gamma-ra…
