The contributions in this volume provide a snapshot of the latest research and future plans for space-borne and ground-based experiments dedicated to the observation of the gamma-ray sky. The articles are authored by both seasoned veterans of the first dedicated gamma-ray missions, and young scientists entering the fascinating field of gamma-ray astrophysics.With the advent of gamma-ray instrumentation on spacecraft and large and sensitive ground-based detectors, new and unexpected phenomena have been discovered, such as gamma-ray bursts and gamma-ray emission from blazars. The immense vitality of the field in the current “post-EGRET era” is witnessed by the numerous ongoing and forthcoming gamma-ray experiments documented here, complementary to various cosmic-ray, neutrino, astroparticle and X-ray projects.

In recent years, cosmic rays have become the protagonists of a new scientific revolution. We are able today to film the Universe with telescopes of completely novel conception, recording information from many different messengers and accessing previously unknown cosmic regions. Written by a recognized authority in physics, this book takes readers on a captivating journey through the world of cosmic rays, their role in the revolutionary field of multi-messenger astronomy, their production from powerful accelerators close to the surfaces of black holes and compact objects, reaching the highest levels of energy observed in nature, and the implications this has for our understanding of the Unive...
This book, written by researchers who had been professionals in accelerator physics before becoming leaders of groups in astroparticle physics, introduces both fields in a balanced and elementary way, requiring only a basic knowledge of quantum mechanics on the part of the reader. The new profile of scientists in fundamental physics ideally involves the merging of knowledge in astroparticle and particle physics, but the duration of modern experiments is such that people cannot simultaneously be practitioners in both. Introduction to Particle and Astroparticle Physics is designed to bridge the gap between the fields. It can be used as a self-training book, a consultation book, or a textbook providing a “modern” approach to particles and fundamental interactions.
This is the sixth edition in a series of Workshops on High Energy Gamma-Ray Experiments, following the ones held in Perugia (2002), Bari (2004), Cividale del Friuli (2005), Elba Island (2006) and Villa Mondragone (2007). The year the focus is on the region known by the acronym VHE (Very High Energy), bridging the gap between GeV and TeV. The physics that lies in this region is of the utmost importance to improve our knowledge of many different astrophysical sources like pulsars, AGNs, GRBs, and our understanding of the main components of the Extragalactic Background Light (EBL). An update is given on the current and planned research for spaceborne and ground-based experiments dedicated to the observation of the gamma-ray sky.
Il giorno in cui Galileo puntò il telescopio al cielo, la luce, «messaggera delle stelle», rivelò all’umanità centinaia di astri mai visti prima. Da allora, grazie a strumenti via via più sofisticati, colori sempre nuovi e invisibili a occhio nudo hanno dato forma alle meraviglie nascoste dell’Universo. Finché, con la scoperta dei raggi cosmici, ha avuto inizio una delle imprese intellettuali più emozionanti della storia della scienza. Queste particelle ad altissima energia segnalano la presenza di enormi acceleratori all’opera nello spazio: resti di supernove e buchi neri supermassicci, fenomeni tra i più violenti nell’Universo. I raggi cosmici sono attualmente al centro di una vera rivoluzione: osservati simultaneamente a neutrini e onde gravitazionali, hanno aperto il campo all’astrofisica multimessaggero, la prodigiosa scienza del XXI secolo che ha ristabilito – per la prima volta dopo Newton – l’unità tra fisica e astronomia. Attraverso un’esposizione rigorosa e appassionata, Alessandro De Angelis ripercorre la storia di questa impresa straordinaria che ha già messo piede nel futuro.

While magnetic fields permeate the universe on all scales, the present book is dedicated to their investigation on the largest scales and affords a balanced account of both theoretical and observational aspects. Written as a set of advanced lectures and tutorial reviews that lead up to the forefront of research, this book offers both a modern source of reference for the experienced researchers as well as a high-level introductory text for postgraduate students and nonspecialist researchers working in related areas.
