Polarization of Thermal X-rays from Isolated Neutron Stars [PDF]

, 1999
Since the opacity of a magnetized plasma depends on polarization of radiation, the radiation emergent from atmospheres of neutron stars with strong magnetic fields is expected to be strongly polarized. The degree of linear polarization, typically ~10-30%,

Polarization-resolved sensing with tilted fiber Bragg gratings: theory and limits of detection [PDF]

, 2015
Polarization based sensing with tilted fiber Bragg grating (TFBG) sensors is analysed theoretically by two alternative approaches. The first method is based on tracking the grating transmission for two orthogonal states of linear polarized light that are

Design of Hollow Core Bragg Fibers for a Compact Fluorescence Sensing Scheme

IEEE Photonics Journal, 2017
We propose a compact fluorescence sensing scheme based on hollow core Bragg fibers (HCBFs) that simultaneously serve as a sample cell, a collector, and a delivery channel for the desired fluorescence, as well as a filter for the residual excitation light

Distortion of Magnetic Fields in a Starless Core V: Near-infrared and Submillimeter Polarization in FeSt 1-457 [PDF]

, 2018
The relationship between submillimeter (submm) dust emission polarization and near-infrared (NIR) $H$-band polarization produced by dust dichroic extinction was studied for the cold starless dense core FeSt 1-457. The distribution of polarization angles (

VLT Spectropolarimetry of the fast expanding Type Ia SN2006X [PDF]

, 2008
Using VLT-FORS1 we performed optical spectropolarimetric observations of the Type Ia SN2006X on 7 pre-maximum epochs (day -10 to day -1) and one post-maximum epoch (+39 days).
