[HgX2] Linear Group Enabled Ultraviolet Birefringent Crystal RbHg5Br11 with Strong Optical Anisotropy and Wide Bandgap

Advanced Science, Volume 12, Issue 45, December 4, 2025.
Based on the “linear‐group” design strategy, a high performance ultraviolet birefringent material RbHg5Br11 with aligned linear [HgBr2] units, demonstrating a large birefringence (Δn ≈ 0.35@546 nm); a wide optical bandgap (≈3.73 eV); as well as a good crystal growth habit; is rationally designed; and fabricated by a simple solution method.

X-Ray Polarimetry as a Tool to Constrain Orbital Parameters in X-Ray Binaries

The Astrophysical Journal
X-ray binary systems consist of a companion star and a compact object in close orbit. Thanks to their copious X-ray emission, these objects have been studied in detail using X-ray spectroscopy and timing.

Prospects for GRB Polarimetry with GRAPE [PDF]

, 2006
This paper discusses the latest progress in the development of GRAPE (Gamma‐Ray Polarimeter Experiment), a hard X‐ray Compton Polarimeter. The purpose of GRAPE is to measure the polarization of hard X‐rays in the 50–300 keV energy range.

Evaluating simulated compact polarimetry for Emergency Geomatics Service flood mapping

, 2020
When severe flooding occurs in Canada, the Emergency Geomatics Service (EGS) is tasked with creating and disseminating maps that depict the flood extent in near real time. These maps delineate open water and flooded vegetation and are created using a combination of raster image processing, machine learning classification, and threshold-based region ...

The effects of disk and dust structure on observed polarimetric images of protoplanetary disks

, 2011
Imaging polarimetry is a powerful tool for imaging faint circumstellar material. For a correct analysis of observations we need to fully understand the effects of dust particle parameters, as well as the effects of the telescope, atmospheric seeing, and ...
