The Interplay Among Black Holes, Stars and ISM in Galactic Nuclei (IAU S222)
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.
21st Century Cosmology
Cosmology findings are increasing rapidly due to the new Research Tools available to astronomy scientists such as the CARMA (space array), the Hubble space borne telescope and others. I have been interested in Cosmology for many years and while I lived in Spain I used information collected from the Internet, once it became available, to give lectures on this subject to the English Speaking Group. This book is a summary of the latest cosmology research collected from the Internet plus information compiled after attending lectures at Caltech on cosmology research. One of the main thrusts of current cosmology research is searching for planets around nearby stars which may have life. The best telescopes when your author attended Caltech from 1947 thru 1951 was the 100 inch mirror in the Mount Wilson dome, later updated to the 200 inch mirror at the Palomar Observatory near San Diego. The new information about the cosmology is exploding at a rapid rate which I find exciting
Gravity's Fatal Attraction
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.
Perseus in Sicily (IAU S342)
Perseus is an outstanding case in which to study the physics of relativistic plasma and thermal gas, and the interplay between galactic nuclei and galaxy clusters. Ground and space observatories have recently provided some ground-breaking insights into the Perseus system, from a detailed image of a jet launched in the vicinity of a supermassive black hole, through VLBI, to an unexpected degree of turbulence in the cluster core, constrained by high energy resolution in x-rays. While preparing for the next generation observatories that will allow readers to address these questions in other systems, this volume provides some first steps in exploring topics relating to particle acceleration, energy transport between large and small scales and the role of magnetic fields in the launch of relativistic jets. Chapters deal with the latest results covering theory, observations, and numerical simulations, spanning a wide range in physical scales and energy ranges.
3+1 Formalism in General Relativity
This graduate-level, course-based text is devoted to the 3+1 formalism of general relativity, which also constitutes the theoretical foundations of numerical relativity. The book starts by establishing the mathematical background (differential geometry, hypersurfaces embedded in space-time, foliation of space-time by a family of space-like hypersurfaces), and then turns to the 3+1 decomposition of the Einstein equations, giving rise to the Cauchy problem with constraints, which constitutes the core of 3+1 formalism. The ADM Hamiltonian formulation of general relativity is also introduced at this stage. Finally, the decomposition of the matter and electromagnetic field equations is presented,...
