Book Description
How massive are the largest and smallest nuclear black holes in galaxies? Why are the masses of nuclear black holes proportional to those of their host galaxy bulges? How is nuclear activity triggered? What are the observational signatures of such processes? What are the connections between the active nucleus, stars and interstellar medium in galaxies? Answers to these questions are addressed in this book, which presents a compilation of 191 works covering recent observations from X-rays to radio wavelengths, as well as theoretical modeling of accretion disks, stellar populations and galaxy and black hole evolution. This volume presents the nuclear activity as a phase in the life of a galaxy, which is intimately connected to the evolution of its stars and interstellar medium. It brings together recent developments in topics covering most aspects of galaxy evolution, and is a valuable resource for astronomers and graduate students working in extragalactic astronomy.

Book Description
Black holes lie at the heart of some of the most fascinating astrophysical phenomena. IAU Symposium 324 marked the 100th anniversary of Schwarzschild's solution of Einstein's field equations predicting the existence of black holes. Our understanding of black holes has come an impressively long way since then, with the last major discovery being coalescing black holes producing gravitational waves, also predicted in 1916. In this volume, observational and theoretical experts discuss the current state-of-the-art in the astrophysics of black-hole systems and their exploitation in testing fundamental theories of physics. Topics span a wide range and include a historical review, the similarity and diversity of black hole systems, gamma ray bursts, tidal disruption events, active galactic nuclei, black hole systems as multi-messenger sources, and the opening of new observational horizons. This fresh review is especially useful to researchers and graduate students engaged in these exciting fields.

Book Description
Star clusters and black holes are moving into the focus of high resolution astrophysics, computationally as well as observationally. For the first time, observations in many regions of the electromagnetic spectrum are converging with theoretical modelling and computer simulations. These cosmological and galaxy formation models reach down to the supermassive black hole level and follow their formation and growth in the centres of galaxies, by gas and star accretion. IAU Symposium 312 brings together experts on high resolution observations as well as theoretical modelling and computational simulations, who present their research on star clusters, black holes and their interrelations, and gravitational wave astrophysics. IAU S312 continues the tradition of IAU symposia on stellar dynamics and related areas, allowing interested graduate students and researchers to access the current state of these fields.

Book Description
IAU Symposium 267 assesses the diverse observational and theoretical attempts to answer the complex question of how quasars physically evolve and how their evolution is tied to those of the host galaxies in which they are found. The emerging theme is that quasars are not only tracers of the evolution of galaxies; they are agents of that evolution. The central black holes in galaxies grow by accretion during a quasar-like phase. However, the accretion process itself eventually produces energetic feedback in the form of intense radiation, massive outflows, and jets, which heat and perhaps remove entirely the interstellar medium of the host galaxy, effectively shutting down star formation. These up-to-date reviews of this dynamic field have particular appeal to newcomers to the field or anyone interested in the 'big picture' of how galaxies and black holes evolve over cosmic time.

Book Description
Quasars, and the menagerie of other galaxies with "unusual nuclei", now collectively known as Active Galactic Nuclei or AGN, have, in one form or another, sparked the interest of astronomers for over 60 years. The only known mechanism that can explain the staggering amounts of energy emitted by the innermost regions of these systems is gravitational energy release by matter falling towards a supermassive black hole --- a black hole whose mass is millions to billions of times the mass of our Sun. AGN emit radiation at all wavelengths. X-rays originating at a distance of a few times the event horizon of the black hole are the emissions closest to the black hole that we can detect; thus, X-rays directly reveal the presence of active supermassive black holes. Oftentimes, however, the supermassive black holes that lie at the centers of AGN are cocooned in gas and dust that absorb the emitted low energy X-rays and the optical and ultraviolet light, hiding the black hole from view at these wavelengths. Until recently, this low-energy absorption presented a major obstacle in observational efforts to map the accretion history of the universe. In 1999 and 2000, the launches of the Chandra and XMM-Newton X-ray Observatories finally broke the impasse. The impact of these observatories on X-ray astronomy is similar to the impact that the Hubble Space Telescope had on optical astronomy. The astounding new data from these observatories have enabled astronomers to make enormous advances in their understanding of when accretion occurs.

Book Description
In published papers H A Bethe and G E Brown worked out the collapse of large stars and supernova explosions. They went on to evolve binaries of compact stars, finding that in the standard scenario the first formed neutron star always went into a black hole in common envelope evolution. C-H Lee joined them in the study of black hole binaries and gamma ray bursts. They found the black holes to be the fossils of the gamma ray bursts. From their properties they could reconstruct features of the burst and of the accompanying hypernova explosions.This invaluable book contains 23 papers on astrophysics, chiefly on compact objects, written over 23 years. The papers are accompanied by illuminating commentary. In addition there is an appendix on kaon condensation which the editors believe to be relevant to the equation of state in neutron stars, and to explain why black holes are formed at relatively low masses.
