This textbook presents ultraviolet and X-ray astronomy gamma-ray astronomy cosmic ray
astronomy neutrino astronomy and gravitational wave astronomy as distinct research areas
focusing on the astrophysics targets and the requirements with respect to instrumentation and
observation methods. The purpose of the book is to bridge the gap between the reference books
and the specialized literature. For each type of astronomy the discussion proceeds from the
orders of magnitude for observable quantities. The physical principles of photon and particle
detectors are then addressed and the specific telescopes and combinations of detectors
presented. Finally the instruments and their limits are discussed with a view to assisting
readers in the planning and execution of observations. Astronomical observations with
high-energy photons and particles represent the newest additions to multimessenger astronomy
and this book will be of value to all with an interest in the field.
