Proceedings Of The Fourth Workshop On Science With The New Generation Of High Energy Gamma Ray Experiments

The research program in gamma-ray astronomy focuses on increasing our knowledge of the nature and origin of galactic and extragalactic gamma rays, and understanding high-energy processes in the Sun, celestial objects, interstellar medium, and extragalactic space.This book not only provides an overview of the latest research and future plans for space-borne and ground-based experiments dedicated to the observation of the gamma-ray sky, but also addresses the topic of variable gamma-ray sources from the perspective of their identification and counterparts at different wavelengths. It further gives an overview of the theory related to the most qualified emission processes that take place in these sources and of the nature of their variability.

Readership: Gamma-ray astronomers; astrophysicists; students and researchers involved in gamma-ray astronomy, both theoretical and experimental; researchers in the development of new gamma-ray detectors.

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.

This book collects contributions presented in the seventh edition in a series of Workshop on High Energy Gamma-ray Experiments. The focus of the Workshop was on Gamma-ray Physics in the LHC Era. In order to understand the origin of the Universe reaserchers are nowadays using two powerful and complementary approaches. On one side radiation produced many years ago and now arriving to us from space, is studied with different experimental techniques. On the other one, particle accelerators can recreate in laboratory the high density high energy state present at the beginning of the Universe. Results are here presented from experiments in space, on earth and underground, regarding cosmic radiation.

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.
