The growth of interest for astronomical X-ray polarimetry

, 2018
Astronomical X-ray polarimetry was first explored in the end of the 60's by pioneering rocket instruments. The craze arising from the first discoveries on stellar and supernova remnant X-ray polarization led to the addition of X-ray polarimeters on-board

X-ray polarimetry small satellite TSUBAME

AIP Conference Proceedings, 2008
“TSUBAME” is a university‐built small satellite mission to measure polarization of hard X‐ray photons (30–100 keV) from Gamma‐ray bursts (GRBs) using azimuthal angle anisotropy of Compton‐scattered photons. Polarimetry in the hard X‐ray and soft γ‐ray band plays a crucial role in the understanding of high energy emission mechanisms and the distribution

The Combination of Chiral Assembly and Chiral Template Effects Boosts Circularly Polarized Luminescence of Perovskite Nanocrystals

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
We show that the hierarchical order of perovskite nanocrystal assemblies formed within a nanostructured, chal liquid‐crystalline template exhibits extremely high circularly polarized luminescence (CPL). This is due to the helical arrangement of PNCs in the template voids and capitalizes on the inherent electrooptic properties of the template ...

To differentiate neutron star models by X-ray polarimetry

, 2013
The nature of pulsar is still unknown because of non-perturbative effects of the fundamental strong interaction, and different models of pulsar inner structures are then suggested, either conventional neutron stars or quark stars.

High Entropy Wide‐Bandgap Borates with Broadband Luminescence and Large Nonlinear Optical properties

Advanced Functional Materials, Volume 36, Issue 35, 30 April 2026.
High‐entropy rare‐earth borates exhibit excellent nonlinear optical and broadband luminescence properties arising from multi‐component doping, chemical disorder, increased configurational entropy, and increased lattice and electronic anharmonicity. This formulation enabled us to obtain a large, environmentally stable single crystal with 3X higher laser‐

X-Ray Spectro-polarimetry with Photoelectric Polarimeters [PDF]

The Astrophysical Journal, 2017
Abstract We derive a generalization of forward fitting for X-ray spectroscopy to include linear polarization of X-ray sources, appropriate for the anticipated next generation of space-based photoelectric polarimeters. We show that the inclusion of polarization sensitivity requires joint fitting to three observed spectra, one for each of ...
