A black hole is a point of extreme mass in space-time with a radius, or event horizon, inside of which all electromagnetic radiation (including light) is trapped by gravity. A black hole is an extremely compact object, collapsed by gravity which has overcome electric and nuclear forces. It is believed that stars appreciably larger than the Sun, once they have exhausted all their nuclear fuel, collapse to form black holes: they are "black" because no light escapes their intense gravity. Material attracted to a black hole, though, gains enormous energy and can radiate part of it before being swallowed up. Some astronomers believe that enormously massive black holes exist in the centre of our galaxy and of other galaxies. This new book brings together leading research from through-out the world.

This book focuses on one mechanism in black hole physics which has proven to be universal, multifaceted and with a rich phenomenology: rotational superradiance. This is an energy extraction process, whereby black holes can deposit their rotational energy in their surroundings, leading to Penrose processes, black-hole bombs, and even Hawking radiation. Black holes are key players in star formation mechanisms and as engines to some of the most violent events in our universe. Their simplicity and compactness make them perfect laboratories, ideally suited to probe new fields or modifications to the theory of gravity. Thus, black holes can also be used to probe some of the most important open problems in physics, including the nature of dark matter or the strong CP problem in particle physics. This monograph is directed to researchers and graduate students and provides a unified view of the subject, covering the theoretical machinery, experimental efforts in the laboratory, and astrophysics searches. It is focused on recent developments and works out a number of novel examples and applications, ranging from fundamental physics to astrophysics. Non-specialists with a scientific background should also find this text a valuable resource for understanding the critical issues of contemporary research in black-hole physics. This second edition stresses the role of ergoregions in superradiance, and completes its catalogue of energy-extraction processes. It presents a unified description of instabilities of spinning black holes in the presence of massive fields. Finally, it covers the first experimental observation of superradiance, and reviews the state-of-the-art in the searches for new light fields in the universe using superradiance as a mechanism.

This textbook gradually introduces the reader to several topics related to black hole physics with a didactic approach. It starts with the most basic black hole solution, the Schwarzschild metric, and discusses the basic classical properties of black hole solutions as seen by different probes. Then it reviews various theorems about black hole properties as solutions to Einstein gravity coupled to matter fields, conserved charges associated with black holes, and laws of black hole thermodynamics. Next, it elucidates semiclassical and quantum aspects of black holes, which are relevant in ongoing and future research. The book is enriched with many exercises and solutions to assist in the learning. The textbook is designed for physics graduate students who want to start their research career in the field of black holes; postdocs who recently changed their research focus towards black holes and want to get up-to-date on recent and current research topics; advanced researchers intending to teach (or learn) basic and advanced aspects of black hole physics and the associated mathematical tools. Besides general relativity, the reader needs to be familiar with standard undergraduate physics, like thermodynamics, quantum mechanics, and statistical mechanics. Moreover, familiarity with basic quantum field theory in Minkowski space is assumed. The book covers the rest of the needed background material in the main text or the appendices.

What would happen if you fell into a Black Hole? Black holes are found throughout the universe. They can be microscopic. They can be billions of times larger than our Sun. They are dark on the outside but not on the inside. Anything that enters them can never escape, and yet they contain nothing at all. In Black Hole Survival Guide physicist and novelist Janna Levin takes you on a journey into a black hole, explaining what would happen to you and why. In the process you'll come to see how their mysteries contain answers to some of the most profound questions ever asked about the nature of our universe.

The supermassive black hole in the center of our Milky Way is the nearest such object and relatively easy to observe and study. Not surprisingly therefore, it is the best studied supermassive black hole. Many astrophysical and even general relativistic effects can be investigated in great detail. The Galactic Black Hole: Lectures on General Relativity and Astrophysics provides a systematic introduction to the physics/astrophysics and mathematics of black holes at a level suitable for graduate students, postdocs, and researchers in physics, astrophysics, astronomy, and applied mathematics. The focus is mainly on the supermassive black hole in the center of our Milky Way but the results can be easily generalized taking it as an example. Leading international experts provide first-hand accounts of the observational and theoretical aspects of this black hole. Topics range from the properties of the Schwarzschild metric and the collapse of a black hole, to quantum gravity, and from the structure of the Galaxy to accretion of matter and the emission properties of the Galactic Center black hole.

Smart strategies for pragmatic, science-based growth and sustainable achievement. The Science of Intelligent Achievement teaches you the scientific process of finding success through your most valuable assets: · Selective focus – how selective are you with who and what you let into your life? · Creative ownership – how dependent are you on others for your happiness and success? · Pragmatic growth – how consistently and practically are you growing daily? First, this book will show you how to develop your focus by being very selective with where you spend your mental energy. If you've failed to reach an important goal because you were distracted, misinformed, or overcommitted, then you know the role focus and selectivity play in achievement. Second, you will learn how to stop allowing your happiness and success to be dependent on other people and instead, start taking ownership over your life through creative work. Finally, you will learn the art of changing your life through pragmatic decisions and actions. Self-improvement is not the result of dramatic changes. Instead, science has shown that personal and professional change is initiated and sustained by consistent, practical changes. To grow, you must leverage the power of micro-decisions, personality responsibility, and mini-habits. Your own biology will not let you improve your life in any other way. What do you currently value? What are working to attain? Have you been taught to value your job title or your relationship with some other person above all else? Have you been convinced that the most valuable things in life are your paycheck, the number of people who say 'hello' to you at the office, and the number of people who say 'I need you' at home? Or, have you become so passive in what you value that you let anyone and anything into your life, as long as whatever you let in allows you to stay disconnected from the cold hard truth that when things really go wrong in your life, the only person who will be able to fix it and the only person will be responsible for it is you. If so…welcome to fake success. Passivity, dependence, and the sacrifice of practical thinking and personal responsibility to fuzzy, grandiose ideals and temporary feelings — these are markers of fake success. Intelligent Achievement, on the other hand, is not a moving target. It's not empty either. Instead, it's sturdy, full, and immovable. It's not something that's just handed to you. It's not something you're nudged to chase or coerced into wanting. Intelligent Achievement comes from within you. It's a collection of values that are aligned with who you are—values you have to protect and nurture. These values do not increase your dependence on other people and things. Instead, they relieve you of dependence. This kind of achievement is something that you have a part in building from the ground up—you know what's in it—you chose it, someone else didn't choose it for you. Achieving real success means you must focus, create, and grow daily. The Science of Intelligent Achievement will show you how.
