Precision Spectroscopy in Astrophysics
High-accuracy Doppler shift measurements and high-precision spectroscopy are primary techniques in the search for exo-planets. Further extremely interesting applications include the analysis of QSO absorption lines to determine the variability of physical constants and the analysis of the isotopic ratios of absorption lines both in stars and in QSOs, and the determination of stellar oscillations through radial velocity measurements. Since the use of high-precision/resolution spectroscopy is closely connected to the ability to collect a large number of photons, the scientific domains using this technique benefit tremendously from the use of 8-meter class telescopes and will fully exploit the tremendous gain provided by future Extremely Large Telescopes (ELTs). IR high-resolution spectroscopy should soon approach the same accuracy regime achieved in the optical range. This volume comprehensively covers the astrophysical and technical aspects of high-precision spectroscopy with an outlook to future developments, and represents a useful reference work for researchers in those fields.

Astronomy and Astrophysics - Volume I
Astronomy is the science of everything – with the exception of the Earth and everything on it and inside. Astronomy has a rich heritage dating back to the myths and legends of antiquity and the course of civilization has been greatly affected by mankind’s interpretation of what they saw in the starry sky and experienced through seasonal changes associated with the Sun and Moon. Early astronomy is associated with the definition of calendars which were needed to predict the dates of such as religious festivals and the numbers of months. A gradual shift of emphasis from astronomy to its sister, astrophysics, which took place through the 19th century, is generally attributed to the measureme...

Proceedings volume for researchers and graduate students of astronomy, covering the most exciting science and key ELT projects.
Current Issues in Cosmology
Many of the world's leading players in cosmology look at the strengths and weaknesses of the current big bang model in explaining certain puzzling data. A comprehensive coverage of the expanding field of cosmology, this text will be valuable for graduate students and researchers in cosmology and theoretical astrophysics.
Total Eclipses
Lively and easy to understand, Total Eclipses presents the myths and legends associated with solar and lunar eclipses through the ages, the mechanisms governing these events, their beauty, and the wealth of information gleaned from them by astronomers and astrophysicists. "Gives a wide variety of information on observing eclipses for the novice as well as on the value of eclipses to professionals...any reader can find information at an interesting and appropriate level and can be sure that he is being guided knowledgeably." -NATURE
Organizations and Strategies in Astronomy 6
When I wasa child, growing up in South America,I often went camping in the wild and hence had direct access to the wondrous Southern sky; the Southern Cross was all mine at the time. Little did I know then that the study of the sky would take such a huge importance in my life, and that in the end astronomy and astrophysics would in many ways become my country and my religion. I have lived in several di?erent countries, and when asked my nationality, I am always very tempted to reply: astronomer. I started as a theorist, and my only dream in my youth was to spend nights thinking and calculating, with paper and pencil, and to have the impression by dawn that I had understood something new. So ...
