Progress in modern radio astronomy led to the discovery of space masers in the microwave range, and it became a powerful tool for studies of interstellar star-forming molecular clouds. Progress in observational astronomy, particularly with ground-based huge telescopes and the space-based Hubble Space Telescope, has led to recent discoveries of space lasers in the optical range. These operate in gas condensations in the vicinity of the mysterious star Eta Carinae (one of the most luminous and massive stars of our Galaxy). Both maser and laser effects, first demonstrated under laboratory conditions, have now been discovered to occur under natural conditions in space, too. This book describes consistently the elements of laser science, astrophysical plasmas, modern astronomical observation techniques, and the fundamentals and properties of astrophysical lasers. A book with such an interdisciplinary scope has not been available to date. The book will also be useful for a wider audience interested in modern developments of the natural sciences and technology.

The Les Houches Summer School in August 2015 covered the emerging fields of cavity optomechanics and quantum nanomechanics. Optomechanics is flourishing and its concepts and techniques are now applied to a wide range of topics. Modern quantum optomechanics was born in the late 1970s in the framework of gravitational wave interferometry, with an initial focus on the quantum limits of displacement measurements. Carlton Caves, Vladimir Braginsky, and others realized that the sensitivity of the anticipated large-scale gravitational-wave interferometers (GWI) was fundamentally limited by the quantum fluctuations of the measurement laser beam. After tremendous experimental progress, the sensitivity of the upcoming next generation of GWI will effectively be limited by quantum noise. In this way, quantum-optomechanical effects will directly affect the operation of what is arguably the world's most impressive precision experiment. However, optomechanics has also gained a life of its own with a focus on the quantum aspects of moving mirrors. Laser light can be used to cool mechanical resonators well below the temperature of its environment. After proof-of-principle demonstrations of this cooling in 2006, a number of systems were used as the field gradually merged with its condensed matter cousin (nanomechanical systems) to try to reach the mechanical quantum ground state, eventually demonstrated in 2010 by pure cryogenic techniques and just one year later by a combination of cryogenic and radiation-pressure cooling. The book covers all aspects - historical, theoretical, experimental - of the field, with its applications to quantum measurement, foundations of quantum mechanics and quantum information. It is an essential read for any new researcher in the field.

A multitude of measurement units exist within astronomy, some of which are unique to the subject, causing discrepancies that are particularly apparent when astronomers collaborate with researchers from other disciplines in science and engineering. The International System of Units (SI) is based on seven fundamental units from which other units may be derived, but many astronomers are reluctant to drop their old and familiar systems. This handbook demonstrates the ease with which transformations from old units to SI units may be made. Using worked examples, the author argues that astronomers would benefit greatly if the reporting of astronomical research and the sharing of data were standardized to SI units. Each chapter reviews a different SI base unit, clarifying the connection between these units and those currently favoured by astronomers. This is an essential reference for all researchers in astronomy and astrophysics, and will also appeal to advanced students.

This 2002 introduction to the use of radar for remote sensing of natural surfaces provides the reader with a thorough grounding in practical applications, focusing particularly on terrestrial studies that may be extended to other planets. An historical overview of the subject is followed by an introduction to the nomenclature and methodology pertaining to radar data collection, image interpretation and surface roughness analysis. The author then presents a summary (illustrated with black and white examples from the natural environment) of theoretical explanations for the backscatter properties of continuous rough surfaces, collections of discrete objects, and layered terrain. Case studies of radar surveys of the Moon, Mercury, Venus and Mars complete the book. The level is appropriate for students and professionals across a broad range of scientific disciplines including Earth and planetary sciences, electrical engineering, and remote sensing. Particular emphasis is given to practical geological and geophysical studies of the terrestrial planets.

This handbook by George Frederick Chambers (1841 1915), a young and enthusiastic amateur astronomer, became a best-seller soon after its publication in 1861 and made Chambers' reputation as a popular astronomy writer. The work is divided into ten parts covering the following topics: the planets of our solar system; eclipses; gravity and tides; phenomena including aberration and refraction; comets; chronological astronomy; stars; astronomical instruments; the history of astronomy; and meteoric astronomy. It is richly illustrated with photographs and woodcuts depicting a wide variety of astronomical phenomena. Chambers went on to become one of the leading amateur astronomers of the nineteenth century. The usefulness and accessibility of his practical advice ensured that his published works became indispensable for thousands of less famous amateurs. The Handbook, reissued in many editions, remains his most popular work and is a key text in the history of Victorian popular astronomical writing.

Since its foundation in 1904, the Mount Wilson Observatory has been at the centre of the development of astrophysics. Perched atop a mountain wilderness, two mammoth solar tower telescopes and the 60- and 100-inch behemoth night-time reflectors were all the largest in the world. Research has centred around two main themes - the evolution of stars and the development of the universe. This first volume in a series of five histories of the Carnegie Institution describes the people and events, the challenges and successes that the Observatory has witnessed. It includes biographical sketches of forty of the most famous Mount Wilson pioneer astronomers working during the first half of the twentieth century. Contemporary photographs illustrate the development and use of some of the innovative instruments that filled the observatory during this time. This story brings together the elements that formed modern theories of stellar evolution and cosmology.
