The review articles collected in this volume present a critical assessment of particle acceleration mechanisms and observations from suprathermal particles in the magnetosphere and heliosphere to high-energy cosmic rays, thus covering a range of energies over seventeen orders of magnitude, from 103 eV to 1020 eV. The main themes are observations of accelerated populations from the magnetosphere to extragalactic scales and assessments of the physical processes underlying particle acceleration in different environments (magnetospheres, the solar atmosphere, the heliosphere, supernova remnants, pulsar wind nebulae and relativistic outflows). Several contributions review the status of shock acceleration in different environments and also the role of turbulence in particle acceleration. Observational results are compared with modelling in different parameter regimes. The book concludes with contributions on the status of particle acceleration research and its future perspectives. This volume is aimed at graduate students and researchers active in astrophysics and space science. Previously published in Space Science Reviews journal, Vol. 173 Nos. 1-4, 2012.

Presents a comprehensive review of physical processes in astrophysical plasmas.This title presents a review of the detailed aspects of the physical processes that underlie the observed properties, structures and dynamics of cosmic plasmas. An assessment of the status of understanding of microscale processes in all astrophysical collisionless plasmas is provided. The topics discussed include turbulence in astrophysical and solar system plasmas as a phenomenological description of their dynamic properties on all scales; observational, theoretical and modelling aspects of collisionless magnetic reconnection; the formation and dynamics of shock waves; and a review and assessment of microprocesses, such as the hierarchy of plasma instabilities, non-local and non-diffusive transport processes and ionisation and radiation processes. In addition, some of the lessons that have been learned from the extensive existing knowledge of laboratory plasmas as applied to astrophysical problems are also covered. This volume is aimed at graduate students and researchers active in the areas of cosmic plasmas and space science. Originally published in Space Science Reviews journal, Vol. 278/2-4, 2013.

Thisbook offers eleven coordinated reviews on multi-scalestructure formation in cosmic plasmas in the Universe. Observations and theories of plasma structures are presentedin all relevant astrophysical contexts, from the Earth’s magnetosphere  through heliospheric and galactic scales to  clusters of galaxies and the large scalestructure of the Universe. Basic processes in cosmic plasmas starting fromelectric currents and the helicity concept governing the dynamics of magnetic structures in planet magnetospheres,stellar winds, and relativistic plasma outflows like pulsar wind nebulae andActive Galactic Nuclei jets are covered. Themulti-wavelength view from the radio to gamma-rays with modern high resolutiontelescopes discussed in the book reveals a beautiful and highly informativepicture of both coherent and chaotic plasma structures tightly connected bystrong mutual influence. The authors are all leading scientists in theirfields, making this book an authoritative, up‐to‐date and enduring contributionto astrophysics.

Relativistic objects in astrophysics present a diverse set of phenomena and cover vast ranges of time scales and spatial scales, but their descriptions rely on a similar backbone: production of a relativistic outflow in a central compact object and dissipation of the outflow at large radii, accompanied by acceleration of particles up to very high energies and production of secondary non-thermal electromagnetic radiation. This book provides a timely and comprehensive review of the main physical processes involved in the formation and dissipation of relativistic outflows. It will be particularly useful to postgraduate students and researchers active in various areas of astrophysics and space science​. Originally published in Space Science Reviews, Volume 207, Issue 1-4, July 2017

From early Chinese astronomy to the most recent high precision, multi-wavelength observations, supernovae have been actively examined for centuries. In recent years, this intense study has yielded great insight into the physics of supernovae and their impact on a wide variety of subjects, from cosmology to astrobiology. The unprecedented growth of observational information, the ever increasing computational power for modeling, and the deep multidisciplinary connections of supernovae to stellar physics, galactic evolution, astrochemistry, and cosmic ray origin motivated the publication of this contributed volume. The book provides insights on current progress in the field and presents open-ended questions for future supernova studies.Originally published in Space Science Reviews in the Topical Collection "Supernovae"

"The Heliosphere in the Local Interstellar Medium", the Proceedings of the First ISSI Workshop 6-10 November 1995, Bern, Switzerland, edited by R. von Steiger, R. Lallement, and M.A. Lee and published in 1996, was the first International Space Science Institute (ISSI) book in the Space Sciences Series. This book covers the knowledge gained in the subsequent 27 years that revolutionized our understanding of the interaction of the heliosphere with the very local interstellar medium (VLISM). Entirely new regions of space have been explored! The Voyagers both crossed the termination shock, passed through the heliosheath, crossed the heliopause, and entered the interstellar medium. New Horizons was launched with more modern instrumentation and explores low-latitude regions of the outer heliosphere. Energetic neutral atoms observed by IBEX and CASSINI allowed exploration of the heliosphere over the whole sky. The initial reconnaissance of the heliosphere and VLISM is complete with in situmeasurements, observations of energetic neutral atoms (ENAs), neutral VLISM H and He, UV emissions, and interstellar dust.This book is a collection reviews from experts in the many aspects of this field that describe the current state of knowledge of the heliosphere’s interaction with the interstellar medium, puzzles yet to be solved, and future plans to continue these studies.
