With the success of Cherenkov Astronomy and more recently with the launch of NASA’s Fermi mission, very-high-energy astrophysics has undergone a revolution in the last years. This book provides three comprehensive and up-to-date reviews of the recent advances in gamma-ray astrophysics and of multi-messenger astronomy. Felix Aharonian and Charles Dermer address our current knowledge on the sources of GeV and TeV photons, gleaned from the precise measurements made by the new instrumentation. Lars Bergström presents the challenges and prospects of astro-particle physics with a particular emphasis on the detection of dark matter candidates. The topics covered by the 40th Saas-Fee Course present the capabilities of current instrumentation and the physics at play in sources of very-high-energy radiation to students and researchers alike. This book will encourage and prepare readers for using space and ground-based gamma-ray observatories, as well as neutrino and other multi-messenger detectors.

High-energy astrophysics has unveiled a Universe very different from that only known from optical observations. It has revealed many types of objects in which typical variability timescales are as short as years, months, days, and hours (in quasars, X-ray binaries, etc), and even down to milli-seconds in gamma ray bursts. The sources of energy that are encountered are only very seldom nuclear fusion, and most of the time gravitation, a paradox when one thinks that gravitation is, by many orders of magnitude, the weakest of the fundamental interactions. The understanding of these objects' physical conditions and the processes revealed by high-energy astrophysics in the last decades is nowadays part of astrophysicists' culture, even of those active in other domains of astronomy. This book evolved from lectures given to master and PhD students at the University of Geneva since the early 1990s. It aims at providing astronomers and physicists intending to be active in high-energy astrophysics a broad basis on which they should be able to build the more specific knowledge they will need. While in the first part of the book the physical processes are described and derived in detail, the second part studies astrophysical objects in which high-energy astrophysics processes are crucial. This two-pronged approach will help students recognise physical processes by their observational signatures in contexts that may differ widely from those presented here.

High energy astrophysics is one of the most exciting areas of contemporary astronomy, covering the most energetic phenomena in the universe. The highly acclaimed first edition of Professor Longair's book immediately established itself as an essential textbook on high energy astrophysics. In this complete revision, the subject matter has expanded to the point where two volumes are desirable. In the first, a thorough treatment is given of the physical processes that govern the behavior of particles in astrophysical environments such as interstellar gas, neutron stars, and black holes. Special emphasis is placed on how observations are made in high energy astrophysics and the limitations imposed on them. The tools of the astronomer and high energy astrophysicist are introduced in the context of specific astronomical problems. The material in Volume 1 leads to a study of all kinds of high energy phenomena in the galaxy and universe given in the second volume. This book assumes that readers have some knowledge of physics and mathematics at the undergraduate level, but no prior knowledge of astronomy is required. The pair of books covers all aspects of modern high energy astrophysics to the point where current research can be understood.

High energy gamma-ray photons are the prime probes of the relativistic or high-energy universe, populated by black holes, neutron stars, supernovae, quasars, and matter-antimatter annihilations. Through studying the gamma-ray sky, astrophysicists are able to better understand the formation and behavior of these exotic and energetic bodies. Very High Energy Gamma-Ray Astronomy summarizes the status of gamma-ray astronomy at energies between 30MeV and 50TeV at a critical point in the development of the discipline: the hiatus between the demise of the EGRET telescope and the launch of the next generation of space telescopes. Starting with an overview of the astrophysics of the bodies that generate high energy gamma rays, it proceeds to discuss the latest developments in observational techniques and equipment. By presenting the techniques, observations, and theories of this expanding frontier, Very High Energy Gamma-Ray Astronomy aids experimentalists and theoreticians in detecting and explaining gamma rays of the highest energies.

Many kinds of radiation exist in the universe, including photons and particles with a wide range of energies. Some of the radiation is produced in stars and galaxies, and some is cosmological background radiation, a relic from the history of cosmic evolution. Among all this radiation, the most energetic are cosmic ray particles: nucleons, nuclei, and even extremely energetic gamma rays. There are some observational facts about cosmic rays to give suggestions on their origin. The most important one among them is that the energy spectrum of high energy cosmic rays above 10 GeV (where the magnetic field of the sun is no longer a concern) is well represented by a power law form. This indicates cosmic ray particles are products of non-thermal processes. Their energy extends over more than 13 decades from 107 eV up to 1020 eV. In terms of its structure, the spectrum can be divided into three regions: two 'knees' and one 'ankle'. The first 'knee' appears around 3×1015 eV where the spectral power law index changes from -2.7 to -3.0. The second 'knee' is somewhere between 1017 eV and 1018 eV where the spectral slope changes from -3.0 to around -3.3. The 'ankle' is seen at or after 3×1018 eV. Above that energy the spectral slope is around -2.7, but with a large uncertainty because of poor statistics and resolution. This book deals with the final and most energetic population, the Ultra High Energy Cosmic Rays (UHECRs).

In the last two decades, cosmology, particle physics, high energy astrophysics and gravitational physics have become increasingly interwoven. The intense activity taking place at the intersection of these disciplines is constantly progressing, with the advent of major cosmic ray, neutrino, gamma ray and gravitational wave observatories for studying cosmic sources, along with the construction of particle physics experiments using beams and signals of cosmic origin. This book provides an up-to-date overview of the recent advances and potential future developments in this area, discussing both the main theoretical ideas and experimental results. It conveys the challenges but also the excitement associated with this field. Written in a concise yet accessible style, explaining technical details with examples drawn from everyday life, it will be suitable for undergraduate and graduate students, as well as other readers interested in the subject.

Gamma ray astronomy, the branch of high energy astrophysics that studies the sky in energetic γ-ray photons, is destined to play a crucial role in the exploration of nonthermal phenomena in the Universe in their most extreme and violent forms. The great potential of this discipline offers impressive coverage of many “hot topics” of modern astrophysics and cosmology, such as the origin of galactic and extragalactic cosmic rays, particle acceleration and radiation processes under extreme astrophysical conditions, and the search for dark matter. The recent observational results and exciting theoretical predictions provide a strong rationale for a deep study of cosmic radiation with forthcoming satellite-borne and ground-based detectors in the so-called very high energy domain of the electromagnetic spectrum above 1010 eV. This invaluable book presents the motivations and highlights the principal objectives of the field, as well as demonstrates its intrinsic links to other branches of high energy astrophysics. Preference is given to three topical areas: (i) origin of cosmic rays; (ii) physics and astrophysics of relativistic jets; (iii) observational gamma ray cosmology. Also, an essential part of the book is devoted to the discussion of the principal mechanisms of production and absorption of energetic γ-rays in different astrophysical environments, as well as to the description of the detection methods of high energy cosmic γ-radiation. Contents:Status of the FieldGamma Ray Production and Absorption MechanismsGamma Rays and Origin of Galactic Cosmic RaysGamma Ray Visibility of Supernova RemnantsPulsars, Pulsar Winds, PlerionsGamma Rays Expected from MicroquasarsLarge Scale Jets of Radio Galaxies and QuasarsNonthermal Phenomena in Clusters of GalaxiesTeV Blazars and Cosmic Background RadiationHigh Energy Gamma Rays — Carriers of Unique Cosmological Information Readership: Astrophysicists, cosmic ray physicists, cosmologists and high energy physicists. Keywords:Reviews:“The author has been an active player in the pioneering experiments that opened the ‘last electromagnetic window’ at photon energies beyond GeV, or wavelengths smaller than 10–13 cm. This is a timely in-depth review of gamma ray astronomy, a field exploding with new instrumentation: space-borne detectors aiming for astronomy with thousands of sources and ground-based detectors hunting for the origin of the cosmic rays, still enigmatic one century after their discovery.”Francis Halzen University of Wisconsin “‘Very high-energy gamma-ray astronomy’ is now beginning to play a crucial role in understanding the high-energy phenomena in the Universe. Flix Ahranonian clearly describes the implication of this new developing field relating to Cosmic-ray Physics, X-ray and low energy gamma-ray astronomy, Potential Extragalactic sources and Cosmologies and dark matter … His writing covers what is known, what is to be explored in future, and also speculating on some new exciting unknown phenomena. He is one of the pioneers and a leading scientist in this field, and this book is timely and valuable for the students and researchers in this field which developed so quickly in recent years together with the scientists who have interest and wish to understand and research the high-energy phenomena in the Universe.”Emeritus Professor Jun Nishimura The University of Tokyo, and Institute of Space and Astronuatical Science “In the entire text Aharonian attaches importance to analytic descriptions. He outlined, discusses and quotes numerous model calculations as well as an abundance of experimental data. The Bibliography is very extensive. This is a recommendable book.”Physik Journal

What role does viscosity play in accretion discs? How do you calculate the 'glitch function' of a pulsar? And can strong shocks account for the energy spectrum of electrons in our Galaxy? These are just some of the exciting questions that Professor Longair uses to develop the physics needed by the astronomer and high energy astrophysicist. The highly acclaimed first edition of High Energy Astrophysics instantly established itself as a classic in the teaching of contemporary astronomy. Reflecting the immense interest and developments in the subject, Professor Longair has developed the second edition into three texts; in this second volume he provides a comprehensive discussion of the high energy astrophysics of stars, the Galaxy and the interstellar medium. He develops an understanding for the essential physics with an elegance and infectious enthusiasm for which his teaching is internationally renowned, illustrating the issues throughout with results from forefront research. This book takes the student with a knowledge of physics and mathematics at the undergraduate level - but not necessarily with training in astronomy - to the point where current astronomical research can be understood.
