The bright future of X-ray polarimetry

Frédéric Marin
(Observatoire de Strasbourg)

50 years after the pioneering experiments, X-ray spectroscopy and timing techniques can be considered as well established. Nonetheless, one prominent feature of X-ray light has not been explored as scrupulously as others: its polarization. Between 1980 and 2000, the instruments were not sensitive enough to go beyond the first X-ray polarimetric results acquired in the 70s but the development of new detection techniques in the early 2000s revived the field. The first X-ray spatial mission to fly a new generation polarimeter will be launched by NASA in 2021 and a couple of balloon-borne experiments are being considered. Following the increasing interest of the community to the unexplored phase space of X-ray polarization, I will present the discoveries X-ray polarimetry is about to make.

Café, thé et biscuits seront servis après le séminaire...
