Security Challenges in Humanitarian Assistance

Autor: Janos Besenyo, Sándor Horvath, Béla Szilagyi

Political, social and climatic changes in the world are accelerating, resulting in man-made industrial disasters, wars, natural disasters, epidemic emergencies and population migrations. As societies are ageing in many countries around the world, the

We present a detailed investigation into the properties of GW170729, the gravitational wave with the most massive and distant source confirmed to date. We employ an extensive set of waveform models, including new improved models that incorporate the

We present results on the inspiral, merger, and post-merger evolution of a neutron star - neutron star (NSNS) system. Our results are obtained using the hybrid pseudospectral-finite volume Spectral Einstein Code (SpEC). To test our numerical methods,

An explicit harmonic code for black-hole evolution using excision

Autor: Luciano Rezzolla, Jonathan Thornburg, Bela Szilagyi, Jeffrey Winicour, Denis Pollney

Publikováno v: Classical and Quantum Gravity

We describe an explicit in time, finite-difference code designed to simulate black holes by using the excision method. The code is based upon the harmonic formulation of the Einstein equations and incorporates several features regarding the well-pose

We report new results which establish that the accurate 3dimensional numerical simulation of generic single-black-hole spacetimes has been achieved by characteristic evolution with unlimited long term stability. Our results cover a selection of disto
