XIPE: the x-ray imaging polarimetry explorer [PDF]

Space Telescopes and Instrumentation 2016: Ultraviolet to Gamma Ray, 2016
XIPE, the X-ray Imaging Polarimetry Explorer, is a mission dedicated to X-ray Astronomy. At the time of writing XIPE is in a competitive phase A as fourth medium size mission of ESA (M4). It promises to reopen the polarimetry window in high energy Astrophysics after more than 4 decades thanks to a detector that efficiently exploits the photoelectric ...

The Growth of Interest in Astronomical X-Ray Polarimetry [PDF]

Galaxies, 2018
Astronomical X-ray polarimetry was first explored in the end of the 1960s by pioneering rocket instruments. The craze arising from the first discoveries of stellar and supernova remnant X-ray polarization led to the addition of X-ray polarimeters to ...

X-ray polarimetry on-board of HXMT [PDF]

SPIE Proceedings, 2008
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 focus of grazing incidence X-ray telescopes. HXMT is a mission by the Chinese Space Agency aimed to survey the Hard X-ray Sky with Phoswich detectors, by exploitation of the ...

X-ray Polarimetry of X-ray Pulsars

Galaxies
Radiation from X-ray pulsars (XRPs) was expected to be strongly linearly polarized owing to a large difference in their ordinary and extraordinary mode opacities. The launch of IXPE allowed us to check this prediction. IXPE observed a dozen X-ray pulsars,

Highly Chiral MoS₂ Flakes With Redox-Active Centers for Spin Selective Water Oxidation. [PDF]

Small Sci
The chiral‐induced spin selectivity effect was realized exploited in Ni‐doped, intrinsically chiral 2D MoS2 flakes to suppress H2O2 production and enhance water oxidation kinetics during water splitting. We propose a hydrothermal synthesis route for highly chiral two‐dimensional flakes of MoS2 doped with single nickel atoms (Ni:MoS2) for spin ...

Decoding THz-Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks. [PDF]

Adv Mater
ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

Synthesis, Structure, and Thin Film Optical Properties of a Chiral Benzothiazole-Derived Squaraine. [PDF]

Chemphyschem
Solution‐processed thin films can be sensitive to the choice of solvent and thermal annealing, which we explore for a chiral benzothiazole squaraine. We observe peculiarly shaped excitonic circular dichroism in uniaxially anisotropic thin films, in which the presumed Davydov bands are spatially distributed exclusively into in‐plane (UDC) and out‐of ...
