Gravitational lensing and microlensing

Tác giả: Silvia Mollerach, Esteban Roulet

A comprehensive and self-contained exposition of gravitational lensing phenomena. It presents the status of gravitational lensing and microlensing, covering the cosmological applications of the observed lensing by galaxies, clusters and the large scale structures, as well as the microlensing ...

Singular null hypersurfaces in general relativity : light-Like signals from violent astrophysical events

Tác giả: Claude Barrabes, P. A. Hogan

This book presents a comprehensive and self-contained exposition of the mathematical theory of impulsive light-like signals in general relativity. Applications are provided in relativistic astrophysics, cosmology and alternative theories of gravity deduced from string theory. Cataclysmic ...

Electromagnetic analysis using transmission line variables

Tác giả: Maurice Weiner

Mathematically, the procedures are identical with the traditional numerical methods; however, the interpretation and physical appeal of the transmission line matrix are far superior. Any change in the matrix has an immediate physical significance. What is also very important is that the matrix ...
