This book introduces the basic concepts of particle cosmology and covers all the main aspects of the Big Bang Model (expansion of the Universe, Big Bang Nucleosynthesis, Cosmic Microwave Background, large scale structures) and the search for new physics (inflation, baryogenesis, dark matter, dark energy). It also includes the majority of recent discoveries, such as the precise determination of cosmological parameters using experiments like WMAP and Planck, the discovery of the Higgs boson at LHC, the non-discovery to date of supersymmetric particles, and the search for the imprint of gravitational waves on the CMB polarization by Planck and BICEP.

This textbook is based on the authors’ courses on Cosmology, and aims at introducing Particle Cosmology to senior undergraduate and graduate students. It has been especially written to be accessible even for those students who do not have a strong background in General Relativity and quantum field theory. The content of this book isorganized in an easy-to-use style and students will find it a helpful research guide.

This book discusses the state of the art of the basic theoretical and observational topics related to black hole astrophysics. It covers all the main topics in this wide field, from the theory of accretion disks and formation mechanisms of jet and outflows, to their observed electromagnetic spectrum, and attempts to measure the spin of these objects. Black holes are one of the most fascinating predictions of general relativity and are currently a very hot topic in both physics and astrophysics. In the last five years there have been significant advances in our understanding of these systems, and in the next five years it should become possible to use them to test fundamental physics, in particular to predict the general relativity in the strong field regime. The book is both a reference work for researchers and a textbook for graduate students.

This textbook introduces the current astrophysical observations of black holes, and discusses the leading techniques to study the strong gravity region around these objects with electromagnetic radiation. More importantly, it provides the basic tools for writing an astrophysical code and testing the Kerr paradigm. Astrophysical black holes are an ideal laboratory for testing strong gravity. According to general relativity, the spacetime geometry around these objects should be well described by the Kerr solution. The electromagnetic radiation emitted by the gas in the inner part of the accretion disk can probe the metric of the strong gravity region and test the Kerr black hole hypothesis. With exercises and examples in each chapter, as well as calculations and analytical details in the appendix, the book is especially useful to the beginners or graduate students who are familiar with general relativity while they do not have any background in astronomy or astrophysics.<

This book provides a comprehensive introduction to X-ray and gamma-ray astronomy. The first part discusses the basic theoretical and observational topics related to black hole astrophysics; the optics and the detectors employed in X-ray and gamma-ray astronomy; and past, present, and future X-ray and gamma-ray missions. The second part then describes data reduction and analysis, the statistics used in X-ray and gamma-ray astronomy, and demonstrates how to write a successful proposal and a scientific paper. Data reduction in connection with specific X-ray and gamma-ray missions is covered in the appendices. Presenting the state of the art in X-ray and gamma-ray astronomy, this is both a valuable textbook for students and an important reference resource for researchers in the field.

This book highlights a comprehensive coverage of X­‐ray and Gamma‐ray astrophysics. The first and the second parts discuss, respectively, X-ray and Gamma-ray experimental techniques and observatories. The third part is devoted to science, including galactic and extragalactic sources. The fourth and last parts are dedicated to analysis techniques in X-ray and Gamma-ray astronomy: spectral analysis, imagining analysis, timing analysis, and polarimetric analysis. Presenting the state of the art in X-ray and gamma-ray astronomy, this is both a valuable book for students and an important reference resource for researchers in the field.

Einstein''s theory of general relativity is one of the pillars of modern physics and it is our standard framework for describing gravitational fields and the spacetime structure. So far, general relativity has passed all experimental tests and agrees with observations. However, the past few years have seen remarkable observational improvements and new techniques that continually challenge the theory''s predictions: routinely detect the gravitational wave signals from the coalescence of black holes and neutron stars; can image the supermassive black holes at the center of our Galaxy and of the galaxy M87; can analyze the properties of the X-ray radiation emitted from the very inner part of the accretion disks of several black holes; and keep improving laboratory and Solar System experiments.

This book offers an updated self-consistent overview, future perspectives, and challenges of experimental and observational tests of gravity, with both gravitational and electromagnetic spectra. It includes the recent results of laboratory tests of gravity, solar system experiments, tests of gravity in the strong-field regime with astrophysical compact objects, and tests of gravity on large scales with cosmological observations.

This book offers an updated comprehensive review of the rapidly expanding field of GRMHD simulations. In Part I, it reviews the basic equations for GRMHD simulations and for numerical relativity. Part II describes public codes for GRMHD simulations. Part III is devoted to accretion processes onto compact objects in the non-self-gravitating fluid approximation. Part IV reviews the state of the art of GRMHD simulations with self-gravitating fluids. This book represents both a valuable book for graduate students and important reference resource for researchers in the field.
