Polarization measurements of thermal radiation from magnetic white dwarf (MWD) stars have been proposed as a probe axion-photon mixing. The leaving the surface MWD is unpolarized, but if low-mass axions exist then photons polarized parallel to direction MWD's field may convert into axions, which induces linear polarization dependent on strength coupling $g_{a\gamma\gamma}$. We model this proces...

In this letter we propose a physical explanation for recently reported correlations between pairs of close and antipodal gamma-ray bursts from publicly available BATSE catalogue. Our model is based on the cosmological scenario in which bursters are located at cosmological distances of order of 0.5–2 Gpc. Observed distribution of gamma-ray bursts strongly suports this assumption. If so gamma-ray...
