چکیده
We investigate alignments between the spin axes of cosmic voids and the principal axes of nearby superclusters using the Millennium Run simulation of a ΛCDM cosmology. The concept of void spin was first introduced by Lee and Park in 2006 to quantify the tidal effect on voids from the surrounding matter distribution. Our numerical analysis reveals that the void spin axes are strongly aligned with the supercluster minor axes, but anti-aligned with the major axes, and have no correlations with the intermediate axes. We provide physical explanations to this numerical results on the basis of tidally induced correlations. It is expected that our work will provide a new insight into the characterization of the cosmic web on the largest scale.

We investigate the development of electromagnetic cascades in ice using a GEANT Monte Carlo simulation. We examine the Cherenkov pulse that is generated by the charge excess that develops and propagates with the shower. This study is important for the RICE experiment at the South Pole, as well as any test beam experiment which seeks to measure coherent Cherenkov radiation from an electromagneti...
