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

Radio astronomy is a mystery to the majority of amateur astronomers, yet it is the best subject to turn to when desirous of an expanded knowledge of the sky. This guide intends to instruct complete newcomers to radio astronomy, and provides help for the first steps on the road towards the study of this fascinating subject. In addition to a history of the science behind the pursuit, directions are included for four easy-to-build projects, based around long-term NASA and Stanford Solar Center projects. The first three projects constitute self-contained units available as kits, so there is no need to hunt around for parts. The fourth – more advanced – project encourages readers to do their own research and track down items. Getting Started in Radio Astronomy provides an overall introduction to listening in on the radio spectrum. With details of equipment that really works, a list of suppliers, lists of online help forums, and written by someone who has actually built and operated the tools described, this book contains everything the newcomer to radio astronomy needs to get going.

Book Description

The last quarter of the 20th century witnessed the rebirth and maturing of optical interferometry and associated technologies. Major successes spanning from direct detection of stellar pulsations to imaging in the optical were achieved with test-bed systems, some of which have now evolved to facilities open to the astronomical community. The intense activity and rapid growth of this field are a clear sign that interferometry will be a major observational tool in this century both from ground and space. The VLTI is the largest ground-based interferometric facility combining four 8.2-m telescopes with up to eight 1.8-m telescopes. This facility is the first opened on a shared risk basis in 2002, a milestone for the astronomical community. The combination of enhanced sensitivity and common user support bring into grasp a vastly unexplored astrophysical territory. This book presents state of the art optical interferometry in astrophysics. We emphasise new VLTI users by including tutorials in optical interferometry theory and practice, and related instrumentation, as well as reviews in stellar formation and evolution, and extragalactic science.

Book Description

The answers to some of the most fundamental questions in science lie between the stars, in molecular clouds that serve as celestial laboratories. Disentangling the chemistries in extraterrestrial environments can provide clues about how planets form and shed light on problems in terrestrial chemistry that are difficult to investigate in the lab, and even the origins of life. Astrochemistry takes you on a tour of the molecular universe through time and space, starting with the emergence of matter about 13.8 billion years ago. From there, the tour visits the interstellar medium, with an emphasis on molecular clouds where stars are born. It then goes through different evolutionary stages of stars and planets – and the chemistry that emerges alongside them – before ending in our own solar system, where you will learn about chemical delivery by objects such as comets and meteorites.
