Book excerpt: A conference on `Observational Evidence for Black Holes in the Universe' was held in Calcutta during January 10-17, 1998. This was the first time that experts had gathered to debate and discuss topics such as: Should black holes exist? If so, how to detect them? Have we found them? This book is the essence of this gathering. Black holes are enigmatic objects since it is impossible to locate them through direct observations. State-of-the-art theoretical works and numerical simulations have given us enough clues of what to look for. Observations, from both ground and space-based missions, have been able to find these tell-tale signatures. This book is a compendium of our present knowledge about these theories and observations. Combined, they give a thorough idea of whether black holes, galactic as well as extragalactic, have been detected or not. Forty-one experts of the subject have contributed to this volume to make it the most comprehensive to date.

Book excerpt: The main objective of the conference was to focus on whether we have enough evidence for existence of black holes, starting from primordial to galactic, extragalactic. Experts from various communities such as, quasars of several billion solar mass to nano quasars of a few solar mass, presented their views and were unanimous that matter has been found to disappear behind event horizons and that the “standard” view of accretion requires major changes to understand the observations. These proceedings contains the most recent results on black hole astrophysics and astronomy, the multiwavelength satellite observations and on future space missions. Recent findings on the relationship among the compact sources and Gamma-ray bursts have been presented.

Book excerpt: Black holes are one of the most fascinating predictions of general relativity. They are the natural product of the complete gravitational collapse of matter and today we have a body of observational evidence supporting the existence of black holes in the Universe. However, general relativity predicts that at the center of black holes there are spacetime singularities, where predictability is lost and standard physics breaks down. It is widely believed that spacetime singularities are a symptom of the limitations of general relativity and must be solved within a theory of quantum gravity. Since we do not have yet any mature and reliable candidate for a quantum gravity theory, researchers have studied toy-models of singularity-free black holes and of singularity-free gravitational collapses in order to explore possible implications of the yet unknown theory of quantum gravity. This book reviews all main models of regular black holes and non-singular gravitational collapses proposed in the literature, and discuss the theoretical and observational implications of these scenarios.

Available in PDF, EPUB and Kindle. Book excerpt: Based on graduate school lectures in contemporary relativity and gravitational physics, this book gives a complete and unified picture of the present status of theoretical and observational properties of astrophysical black holes. The chapters are written by internationally recognized specialists. They cover general theoretical aspects of black hole astrophysics, the theory of accretion and ejection of gas and jets, stellar-sized black holes observed in the Milky Way, the formation and evolution of supermassive black holes in galactic centers and quasars as well as their influence on the dynamics in galactic nuclei. The final chapter addresses analytical relativity of black holes supporting theoretical understanding of the coalescence of black holes as well as being of great relevance in identifying gravitational wave signals. With its introductory chapters the book is aimed at advanced graduate and post-graduate students, but it will also be useful for specialists.

This book was released on 2001-02-26 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: The observational evidence for the existence of black holes has grown significantly over recent decades. Stellar-mass black holes are detected as X-ray sources in binary systems, while supermassive black holes, with masses more than a million times the mass of the Sun, lurk in the nuclei of galaxies. These proceedings provide a useful and up-to-date overview of the observations of black holes in binaries, in the center of the Milky Way, and in the nuclei of galaxies, presented by leading expert astronomers. Special attention is given to the formation (including the recent evidence from gamma-ray bursts), physical properties, and demographics of black holes.

Available in PDF, EPUB and Kindle. Book excerpt: Richly illustrated with the images from observatories on the ground and in space, and computer simulations, this book shows how black holes were discovered, and discusses our current understanding of their role in cosmic evolution. This second edition covers new discoveries made in the past decade, including definitive proof of a black hole at the center of the Milky Way, evidence that the expansion of the Universe is accelerating, and the new appreciation of the connection between black holes and galaxy formation. There are entirely new chapters on gamma-ray bursts and cosmic feedback. Begelman and Rees blend theoretical arguments with observational results to demonstrate how both approaches contributed to this subject. Clear illustrations and photographs reveal the strange and amazing workings of our universe. The engaging style makes this book suitable for introductory undergraduate courses, amateur astronomers, and all readers interested in astronomy and physics.

Book excerpt: This volume provides a detailed description of some of the most active areas in astrophysics from the largest scales probed by the Planck satellite to massive black holes that lie at the heart of galaxies and up to the much awaited but stunning discovery of thousands of exoplanets. It contains the following chapters: • Jean-Philippe UZAN, The Big-Bang Theory: Construction, Evolution and Status • Jean-Loup PUGET, The Planck Mission and the Cosmic Microwave Background • Reinhard GENZEL, Massive Black Holes: Evidence, Demographics and Cosmic Evolution • Arnaud CASSAN, New Worlds Ahead: The Discovery of Exoplanets Reinhard Genzel and Andrea Ghez shared the 2020 Nobel Prize in Physics “for the discovery of a supermassive compact object at the centre of our galaxy’”, alongside Roger Penrose “for the discovery that black hole formation is a robust prediction of the general theory of relativity”. The book corresponds to the twentieth Poincaré Seminar, held on November 21, 2015, at Institut Henri Poincaré in Paris. Originally written as lectures to a broad scientific audience, these four chapters are of high value and will be of general interest to astrophysicists, physicists, mathematicians and historians.

Available in PDF, EPUB and Kindle. Book excerpt: An astronomer at the Royal Observatory in Edinburgh, Hawkins recounts the train of 20th-century astronomy and his own thought that led him to conclude in 1993 that the 99% of the universe's mass that seems to be missing is in fact contained in tiny primordial black holes. He also looks at the political, social, and philosophical reasons that his theory has yet to be widely accepted by his colleagues. Annotation copyrighted by Book News, Inc., Portland, OR
