Book Description
This book is based upon lectures presented in the summer of 2009 at the INFN-Laboratori Nazionali di Frascati School on Attractor Mechanism, directed by Stefano Bellucci. The symposium included such prestigious lecturers as S. Ferrara, G. Dall'Agata, J.F. Morales, J. Simón and M. Trigiante. All lectures were given at a pedagogical, introductory level, which is reflected in the specific "flavor" of this volume. The book also benefits from extensive discussions about, and the related reworking of, the various contributions. It is the fifth volume in a series of books on the general topics of supersymmetry, supergravity, black holes and the attractor mechanism.

Book Description
Black holes, supernovas, Dark matter, and the micro gravity or macro gravity related researches and studies for analysis can be of inbound curiosity to any professional in any subject stream. These are lessons about nature that is sure to trigger the curiosity in anyone. Shedding some light on these vitalities related to black holes, formation, creation, and deterioration is the objective here. Enormous amount of gases in the black holes, in varied capacities, and the unpredictable size and nature of the black holes, with super gravity, make the studies to be too complicated to understand precisely about the physical properties of the black holes. To describe the difference between gravitational and inertial mass, brings in the need to know on when an astronaut in orbit experiences apparent weightlessness. That is the way to understand on how black holes are formed for anyone else too.

Book Description
In this Thesis, we study black holes and their microscopic properties in extensions of General Relativity that arise as low-energy limits of String Theory. The first question we want to address is how information is released from black holes during evaporation. We make use of quantum information techniques and study information release from qubit systems. We then introduce a general framework to capture the Hawking evaporation process and deduce the constraints unitarity puts on the evolution. This makes the statement of information loss in black hole evaporation more precise and supports the claim that the horizon has to be replaced by a structure, or \emph{fuzzball}, that carries information about the black hole microstates. This immediately raises the question of what this horizon-scale structure is? We address this question in the context of Supergravity. We systematically construct a family of microstates of near-extremal black holes, by placing metastable supertubes inside certain scaling supersymmetric smooth microstate geometries. These non-extremal fuzzballs differ from the classical black hole solution macroscopically at the horizon scale, and for certain probes the fluctuations between various fuzzballs will be visible as thermal noise far away from the horizon. If the black hole horizon is replaced by a horizon-scale structure one can ask what the experience of an observer falling into such a structure is? A recent, much debated, Gedankenexperiment suggests that an infalling observer will burn at a firewall at the horizon. We rephrase this Gedankenexperiment in the decoherence picture of quantum mechanics and ask about the fate of an infalling wave packet. While wave packets of the size of outgoing Hawking quanta can indeed not freely fall through the horizon-scale structure there is a possibility that the experience of macroscopic infalling observers that strongly interact with the structure can have an alternate description of free fall through the horizon of a black hole. We discuss this recently proposed picture of fuzzball complementarity in detail and test it using our newly constructed near-extremal microstates. A key feature of supersymmetric multi-center solutions, used to construct these near-extremal microstates, is that when brane probes are placed in this background in a supersymmetric way they capture the same information as the fully backreacted Supergravity solution. We investigate whether this non-renormalization property also holds for extremal `almost-BPS' solutions where supersymmetry is broken in a controllable way. We find that despite the lack of supersymmetry, the probe action reproduces exactly the equations underlying the fully back-reacted solution indicating that these equations also do not receive quantum corrections.

Book Description
'Includes exciting recent advances in studying gravity and its cosmic manifestations.' Lord Martin Rees, Astronomer Royal, former President of the Royal Society A fascinating historical account of how we have reached our current understanding of gravity. There have been sensational developments in gravitational physics in recent years. The detection of gravitational waves - ripples in the fabric of space - has opened a new window on the universe. These waves are produced by the most cataclysmic events in the universe - the collisions and mergers of black holes and neutron stars. There have also been great strides in our understanding of supermassive black holes. We now know that a black hole with a gargantuan mass lies at the heart of every galaxy, and we even have an image of one such beast. Gravity: From Falling Apples to Supermassive Black Holes provides an engaging and accessible account of how we have reached our current understanding of gravity and places these amazing discoveries in their true context. Gravity: From Falling Apples to Supermassive Black Holes is written in a captivating historical style with stories about the researchers of the past and present that illuminate many key ideas in astronomy and physics. The historical material leads from discussions of the early cosmologies to the great breakthroughs of Tycho and Kepler. We then consider Galileo's contributions to astronomy and mechanics, and the significance of Jeremiah Horrocks's ideas to the Newtonian revolution that would follow. Newton's theories brought about a new scientific age and his description of gravity was unrivalled for over two centuries until it was superseded by Einstein's description in terms of curved spacetime. The outlandish predictions of Einstein's theory have been confirmed again and again, including black holes and gravitational waves. Finally, we move on to more speculative ideas including Hawking radiation and primordial black holes and attempts to find a quantum theory of gravity.

Book Description
These lecture notes are dedicated to the most recent theoretical applications of Black Hole solutions in high-energy physics. The main motivation of this volume is to present the latest black hole backgrounds that are relevant for gauge/gravity correspondence. Leading scientists in the field explain effective techniques for finding singular and cosmological solutions embedded in gauged supergravity, shedding light on underlying properties and symmetries. Starting from a basic level, the mathematical structures underlying black holes and cosmologies are revealed, helping the reader grasp the connection between theoretical approaches and physical observations with insights into possible future developments from both a theoretical and experimental point of view. The topics covered in this volume are based on lectures delivered during the “Theoretical Frontiers in Black Holes and Cosmology” school, held in Natal in June 2015.
