  • This book provides readers with a clear progress to theoretical and observational astrophysics. It is not surprising that astrophysics is continually growing because very sophisticated telescopes are being developed and they bring the universe closer and make it accessible. Astrophysics Book presents a unique opportunity for readers to demonstrate processes do occur in Nature.

  • This textbook offers a succinct and self-contained introduction into general relativity and its main areas of application: compact objects, gravitational waves and cosmology. It has evolved from lecture courses I have taught at the University of Utrecht since 1990. The book is intended for advanced undergraduate and beginning graduate students in physics and astrophysics. The past decades have seen spectacular new developments in our knowledge of cosmology, the physics of compact objects and in high precision gravity experiments.

  • The fields of cosmology and particle astrophysics (sometimes collectively named astroparticle physics) are currently experiencing an era which will most probably be remembered as ‘the golden age’. The developments during the last few years have been truly astonishing, and the planning and building of new detectors, telescopes and other experimental facilities will guarantee an interesting decade to follow.

  • Traditionally astrophysics has concerned itself with minimum time-scales measured in hours rather than seconds. This was understandable as the available recording media were slow; e.g. chart recorders and photographic plates. In the 1950s, 60s and 70s wavebands away from the optical were developed; from ground based radio studies to space and balloon borne high energy work. In contrast to optical wavelengths instrumentation in these (high and low energy) regimes was capable of time resolutions of less than a second....

  • Since their discovery was first announced in 1973, gamma-ray bursts (GRBs) have been among the most fascination objects in the universe. While the initial mystery has gone, the fascination continues, sustained by the close connection linking GRBs with some of the most fundamental topics in modern astrophysics and cosmology. Both authors have been active in GRB observations for over two decades and have produced an outstanding account on both the history and the perspectives of GRB research.

  • This textbook is based on the one-semester course “Introduction to Astrophysics”, taken by third-year Physics students at Tel-Aviv University, which I taught several times in the years 2000-2005. My objective in writing this book is to provide an introductory astronomy text that is suited for university students majoring in physical science fields (physics, astronomy, chemistry, engineering, etc.), rather than for a wider audience, for which many astronomy textbooks already exist.

  • IT HAS BEEN SAID THAT SIR ISAAC NEWTON was the last person to know everything. He was an accomplished physicist (his three laws of motion were the basis of classical mechanics, which defi ned astrophysics for three centuries), mathematician (he was one of the inventors of calculus and developed Newton’s Method for fi nding roots of equations), astronomer, natural philosopher, and alchemist (okay, maybe the last one was a mistake). He invented the refl ecting telescope, a theory of color, and a law of cooling, and he studied the speed of sound.

  • Because of their apparent “simplicity” simple atoms present a great challenge and temptation to experts in various branches of physics from fundamental problems of particle physics to astrophysics, applied physics and metrology. This book is based on the presentations at the International Conference on Precision Physics of Simple Atomic Systems (PSAS 2002) whose primary target was to provide an effective exchange between physicists from different fields.

  • The study of the formation and early evolution of stars has been an ever growing part of astrophysical research. Traditionally, often in the shadow of its big brothers (i.e., the study of stellar structure, stellar atmospheres and the structure of galaxies), it has become evident that early stellar evolution research contributes essentially to these classical fields. There are a few new items on the list of traditional astrophysical studies, some of which are more related to features known from the extreme late stages of stellar evolution.
