Gravitational Lenses (eBook, PDF)

• Format: PDF

Produktbeschreibung

This monograph describes comprehensively and in sufficient detail both the theory and observation of gravitational lensing, an effect that is of growing importance for astronomical observations and cosmological modelling. This book is the first monograph (outside the USSR) on this topic.
