A New Way to Make Waves
I describe a new algorithm for solving nonlinear wave equations. In this approach, evolution takes place on characteristic hypersurfaces. The algorithm is directly applicable to electromagnetic, Yang-Mills and gravitational fields and other systems described by second differential order hyperbolic equations. The basic ideas should also be applicable to hydrodynamics. It is an especially accurat...
متن کاملPolarized Gravitational Waves from Gamma-Ray Bursts
Significant gravitational wave emission is expected from gamma-ray bursts arising from compact stellar mergers, and possibly also from bursts associated with fast-rotating massive stellar core collapses. These models have in common a high angular rotation rate, and observations provide evidence for jet collimation of the photon emission, with properties depending on the polar angle. Here we con...
متن کاملGravitational Waves and γ-Ray Bursts
Coalescing binaries in distant galaxies are one of the most promising sources of gravitational waves detectable by the LIGO project.[1−5] They are also a copious source of neutrinos, however these neutrino pulses are far too weak to be detected on earth. Several years ago Eichler et al. [6] suggested that they are also sources of γ-ray bursts (GRBs). Recently it was found that GRBs are likely t...
متن کاملGravitational Waves from Gamma-ray Bursts
We present a mechanism for long bursts of gravitational radiation from Kerr black holes surrounded by a torus. These systems are believed to form in core-collapse of massive stars in association with gamma-ray bursts. The torus cat-alyzes black hole-spin energy mostly into gravitational radiation, with a minor output in winds, thermal and neutrino emissions. Torus winds impact the remnant envel...
متن کاملIndoor Soccer Team Starting to Make Waves
Unfortunately, the booters started very slowly, getting aced in their first two matchups. Then, last weekend, the Danes turned things around, and defeated a highly ranked Brockport team. 1-0, on a goal by Chepc Ruano. The Danes then went on tolose two overtime matchups. The first came against Morrisville (one of the finest Junior College soccer teams around) losing 2-1. The second loss came aga...
