Book Description
This book reports on the extraordinary observation of TeV gamma rays from the Crab Pulsar, the most energetic light ever detected from this type of object. It presents detailed information on the painstaking analysis of the unprecedentedly large dataset from the MAGIC telescopes, and comprehensively discusses the implications of pulsed TeV gamma rays for state-of-the-art pulsar emission models. Using these results, the book subsequently explores new testing methodologies for Lorentz Invariance Violation, in terms of a wavelength-dependent speed of light. The book also covers an updated search for Very-High-Energy (VHE), >100 GeV, emissions from millisecond pulsars using the Large Area Telescope on board the Fermi satellite, as well as a study on the promising Pulsar Wind Nebula candidate PSR J0631. The observation of VHE gamma rays is essential to studying the non-thermal sources of radiation in our Universe. Rotating neutron stars, also known as pulsars, are an extreme source class known to emit VHE gamma rays. However, to date only two pulsars have been detected with emissions above 100 GeV, and our understanding of their emission mechanism is still lacking.

Book Description
The ideal text for a one-semester course in radio astronomy Essential Radio Astronomy is the only textbook on the subject specifically designed for a one-semester introductory course for advanced undergraduates or graduate students in astronomy and astrophysics. It starts from first principles in order to fill gaps in students' backgrounds, make teaching easier for professors who are not expert radio astronomers, and provide a useful reference to the essential equations used by practitioners. This unique textbook reflects the fact that students of multiwavelength astronomy typically can afford to spend only one semester studying the observational techniques particular to each wavelength band. Essential Radio Astronomy presents only the most crucial concepts—succinctly and accessibly. It covers the general principles behind radio telescopes, receivers, and digital backends without getting bogged down in engineering details. Emphasizing the physical processes in radio sources, the book's approach is shaped by the view that radio astrophysics owes more to thermodynamics than electromagnetism. Proven in the classroom and generously illustrated throughout, Essential Radio Astronomy is an invaluable resource for students and researchers alike. The only textbook specifically designed for a one-semester course in radio astronomy Starts from first principles Makes teaching easier for astronomy professors who are not expert radio astronomers Emphasizes the physical processes in radio sources Covers the principles behind radio telescopes and receivers Provides the essential equations and fundamental constants used by practitioners Supplementary website includes lecture notes, problem sets, exams, and links to interactive demonstrations An online illustration package is available to professors

Book Description
In view of the current and forthcoming observational data on pulsar wind nebulae, this book offers an assessment of the theoretical state of the art of modelling them. The expert authors also review the observational status of the field and provide an outlook for future developments. During the last few years, significant progress on the study of pulsar wind nebulae (PWNe) has been attained both from a theoretical and an observational perspective, perhaps focusing on the closest, more energetic, and best studied nebula: the Crab, which appears in the cover. Now, the number of TeV detected PWNe is similar to the number of characterized nebulae observed at other frequencies over decades of observations. And in just a few years, the Cherenkov Telescope Array will increase this number to several hundreds, actually providing an essentially complete account of TeV emitting PWNe in the Galaxy. At the other end of the multi-frequency spectrum, the SKA and its pathfinder instruments, will reveal thousands of new pulsars, and map in exquisite detail the radiation surrounding them for several hundreds of nebulae. By carefully reviewing the state of the art in pulsar nebula research this book prepares scientists and PhD students for future work and progress in the field.

Book Description
The aim of the inaugural meeting of the Sant Cugat Forum on Astrophysics was to address, in a global context, the current understanding of and challenges in high-energy emissions from isolated and non-isolated neutron stars, and to confront the theoretical picture with observations of both the Fermi satellite and the currently operating ground-based Cherenkov telescopes. Participants have also discussed the prospects for possible observations with planned instruments across the multi-wavelength spectrum (e.g. SKA, LOFAR, E-VLT, IXO, CTA) and how they will impact our theoretical understanding of these systems. In keeping with the goals of the Forum, this book not only represents the proceedings of the meeting, but also a reflection on the state-of-the-art in the topic.

Book Description
For anyone who's ever looked at the night sky and wanted to know more about the galaxy around them, The Practical Astronomer offers a comprehensive guide to discovering and understanding the mysteries of the solar system and beyond. Illustrated with specially commissioned photography and artwork, and using clear, easy-to-follow text, The Practical Astronomer takes you on a step-by-step journey from the basics of what can be seen with the naked eye from your own backyard, to how you can view more distant objects such as the planets of the solar system, and even galaxies far, far away. The book opens with an explanation of the fundamentals of astronomy, detailing when, where, and how to look at the night sky. It goes on to cover the necessary equipment and clothing that the amateur astronomer needs, reviewing optical equipment such as binoculars and telescopes, how they work and how to use them. A special section focuses on photography and covers the "how-to's" of capturing beautiful images of what you see. The Practical Astronomer aims to foster an awareness and understanding of what you're looking at-be it a planet, star, or asteroid. Different sections are devoted to looking at how the night sky changes, whether that's because it's viewed from a different place in the world or at a different time of year. Star charts and detailed maps of the night sky are included to aid budding astronomers in their quest to know more about this fascinating subject.

Book Description
There are 'voids' obscuring all kinds of objects in the cosmos. Voids may be within an object, or between an object and us. Dark Nebulae, Dark Lanes, and Dust Lanes looks out into the deep sky at those apparent dark regions in space, which are among the most compelling telescopic destinations for amateur observers. One famous example is Barnard's dark nebulae - those striking dark clouds set against the background of stars in the Milky Way. But there are countless other less well known examples. These dark regions are often ignored altogether or commented upon only briefly in astronomy books, and it is all too easy to overlook the treasure trove they offer the observer. Dark Nebulae, Dark Lanes, and Dust Lanes is a great source of practical information for observers. Such voids may be successfully observed using conventional observing methods, but they are often far better seen with technologies such as light-pollution filters, CCD video cameras, and image intensifiers. This book explains the optimal ways to observe each object in detail.
