Gravity, Particles and Astrophysics

Physics of the Earth and Planetary Interiors, 1981
Paul Wesson 1981 Dordrecht: D Reidel 276 pp price $34 There have been remarkable developments in the last few years on the interface between particle physics and cosmology. Despite its title, this book is not about these developments.

Particle Astrophysics

2008
Abstract The last years have seen a symbiosis of the fields of elementary particle physics and the astrophysics of the early universe. This text presents the background of the subjects and the latest developments at a level suitable for final year undergraduates and beginning graduate students. The first chapters cover the properties and

The Heliosphere as an Astrophysical Laboratory for Particle Acceleration

Science, 1989
Particle acceleration is one of the most important topics in plasma astrophysics as well as in cosmic-ray astrophysics. The heliosphere is an ideal astrophysical laboratory, wherein one can observe in situ the elementary mechanisms involved in the particle acceleration processes.

Astrophysical particle acceleration

AIP Conference Proceedings, 1986
The observed properties of high energy particles in different astrophysical environments are briefly summarized. It appears that cosmic rays are freely produced with high (up to 10 per cent) efficiency by supersonic flows. At relativistic energies, the integral distribution function of the accelerated particles (i.e., the number of particles with ...

Astrophysical Source Separation Using Particle Filters

2004
In this work, we will confront the problem of source separation in the field of astrophysics, where the contributions of various Galactic and extra-Galactic components need to be separated from a set of observed noisy mixtures. Most of the previous work on the problem perform blind source separation, assume noiseless models, and in the few cases when ...

Particle astrophysics or ‘‘Looking’’ at the stars

AIP Conference Proceedings, 1993
For millennia humankind has looked at the stars and wondered about the universe. Only in recent years have we been able to ‘‘look’’ at the stars by means other than visible light. Not only can we now use photons of other wavelengths—from radio waves to ultra‐high‐energy gamma rays—but we can also detect, or try to detect, other particles. These include

Particle Acceleration in Astrophysics

2001
The general problem of particle acceleration is considered in the Astronomical and Astrophysical context. Recent developments in Fermi acceleration theory, usually called diffusive shock acceleration, are explained in a physically motivated and heuristic fashion.
