Supernova can be polarized by an asymmetry in the explosion process, an off-center source of illumination, scattering in an envelope distorted by rotation or a binary companion, or scattering by the circumstellar dust. Careful polarimetry is the most powerful tool to study the 3-D geometry of supernovae. A deep understanding of the 3-D geometry of SNe is essential in using them as calibrated di...

Interstellar polarization from aligned dust grains can be measured both in transmission at visible and near-infrared wavelengths and in emission at far-infrared and sub-mm wavelengths. These observations can help predict the behavior of foreground contamination of CMB polarimetry by dust in the Milky Way. Fractional polarization in emission from aligned dust grains will be at the higher range o...

The Imaging X-ray Polarimetry Explorer, a NASA small explorer mission, will be the first mission dedicated to x-ray polarimetry. payload consists of three identical telescopes, each comprising mirror module assembly (MMA) with polarization-sensitive detector at its focus. We describe all aspects MMA, from initial optical and mechanical design considerations meet program requirements through she...

Aims: To evaluate different algorithms used to analyse retinal nerve fibre layer thickness (RNFL) data obtained by scanning laser polarimetry, in order to compare their relative abilities to discriminate between patients with glaucomatous localised nerve fibre layer defects and normal subjects. Methods: 48 eyes of 48 glaucomatous patients with localised RNFL defects and 53 eyes of 53 healthy su...

Agricultural targets mainly concern towards the preservation of the soil and crop productivity. Recent study and analysis of radars in the field of agriculture has determined that interaction of the radar pulses with various conditions of soil have significantly affected backscattering. On discussion to soil conditions, may account such as the moisture content availed and soil tillage. Tilling ...

This note describes the RHIC polarization measurements for use by the collider experiments for the Run13 255 GeV polarized proton running period. The measurement procedure is largely identical to that followed for Runs 9-12, described in a previous note [1]. That note should be referred to for details of the polarimetry system and measurement, use of tabulated results [2], and uncertainties, al...
