Gamma-ray bursts  Soft gamma-ray repeaters  Magnetars  Gamma-ray  transient sources  629  1441  992  1853  Astrophysics - High Energy  Astrophysical Phenomena  Abstract: The giant flares of soft gamma-ray repeaters (SGRs) have long been proposed to contribute to at least a subsample of the observed short gamma-ray bursts (GRBs). In this paper, we perform a comprehensive analysis of the high-energy data of the recent bright short GRB 200415A, which was located close to the Sculptor galaxy. Our results suggest that a magnetar giant flare provides the most natural explanation for most observational properties of GRB 200415A, including its location, temporal and spectral features, energy, statistical correlations, and high-energy emissions. On the other hand, the compact star merger GRB model is found to have difficulty reproducing such an event in a nearby distance. Future detections and follow-up observations of similar events are essential to firmly establish the connection between SGR giant flares and a subsample of nearby short GRBs.

The effects of polymer network formed under UV irradiation with electric field application ( 50V  5Hz) to ferroelectric liquid crystal (FLC) molecules orientation and electrooptic characteristics have been studied. The polymer network formed in SmC*phase is anisotropic and fibrils-like  and a typical striped texture was observed in the cell. The FLC gels exhibit a symmetric V-shaped electrooptic characteristics with thresholdless voltage and high contrast ratio (40:1). A theory explanation of the unique properties is given by establishing a molecular orientation model and conducting a computer simulation. A good fitting of the electrooptic dynamic response of FLC gels has been obtained by introducing a potential (bulk anchoring energy) originated from the photo-cured polymer network. 2002 Taylor Francis.
