Available in PDF, EPUB and Kindle. Book excerpt: This second title in the series published for the Space Telescope Science Institute researches the current models of quasar absorption and the systems of absorption lines in the spectra of quasars. Experts in this field discuss the nature of the absorbing process in the vicinity of quasars, the "Lyman-alpha forest", metal-line systems, and quasars as probes of high redshift galaxies. The Hubble Space Telescope will be a valuable tool for learning more about the physics and astronomy of quasars.

Download or read book QSO Absorption Lines written by Georges Meylan and published by Springer. This book was released on 1995-09-18 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The controversial question of whether the majority of the narrow absorption lines observed in QSO spectra represent cosmological intervening systems or ejecta from the QSO themselves is settled. QSO absorption line spectroscopy, initially a mere technique, has matured into an essential extragalactic research tool for understanding the content of the Universe at redshifts between 0 and 4, and beyond. The only previous important meeting devoted to "QSO Absorption Lines" was held in May 1987 at the Space Telescope Science Institute in Baltimore, Maryland, U.S.A. Since that time, nearly a decade ago, research has been ex tremely active in this now well-established field of astrophysics. Theoretical stud ies and simulations have taken advantage of the constant progress in computer technology, and during these last few years, the observational results have bene fited largely from the new facillities offered by the Hubble Space Telescope in the UV wavelength range and the Keck Telescope for high-resolution spectroscopy.

Fact-filled and image-rich guide to the principles of astronomy, its history, a host of fun facts, and helpful tips for the backyard or budding astronomers! We look to the heavens and wonder in awe. Shooting stars, constellations, planets, galaxies, and the unknown. What is out there? Who is out there? How did the stars and planets come to be? What does it all mean? The last few years have brought an explosion of information leading to serious consideration of questions once deemed crazy. Do other universes exist? Are there planets that could harbor life? From a neutron star to a black hole; from the Higgs Boson particle to cosmic strings; from the speed of light to gamma radiation; plus a universe of ideas and concepts in between, The Handy Astronomy Answer Book takes you on a journey through the history, science and the latest findings in astronomy. This book tells the story of astronomy—of the cosmos and its contents, and of humanity’s efforts throughout history to unlock its secrets and solve its mysteries. You’ll learn the answers to more than 1,000 questions on astronomy and space, including ... What is astrobiology? What is the Dresden Codex, and what does it say about Mayan astronomy? What happened between Galileo and the Catholic Church? What is the longest time that a human has been in space? What is a gamma-ray burst? How do I use a star chart to find stars and constellations? How do space and time relate to one another? What were considered to be NASA’s four great observatories in space? How do astronomers map the night sky? How many constellations are there? How has the discovery of exoplanets affected the search for extraterrestrial life? Could a moon found in a star's habitable zone support life as we know it? How will the universe end? From the basic physics and history of astronomy to using star charts, telescopes, and other helpful hints for the home astronomer, and from space mission programs to the greatest adventure of all—the search for life beyond Earth—The Handy Astronomy Answer Book includes information on virtually every topic related to outer space.

Download or read book Statistical Challenges in Modern Astronomy written by Eric D. Feigelson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern astronomy has been characterized by an enormous growth in data acquisition - from new technologies in telescopes, detectors, and computation. One can now compile catalogs of tens or hundreds of millions of stars or galaxies and databases from satellite-based observations are reaching terabit proportions. This wealth of data gives rise to statistical challenges not previously encountered in astronomy. This book is the result of a workshop held at Pennsylvania State University in August 1991 that brought together leading astronomers and statisticians to consider statistical challenges encountered in modern astronomical research. The chapters have all been thoroughly revised in the light of the discussions at the conference, and some of the lively discussion is recorded here as well.
Download or read book Precision Spectroscopy in Astrophysics written by Nuno C. Santos and published by Springer Science & Business Media. This book was released on 2008-01-28 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Galaxy Disk in Cosmological Context IAU S254 written by International Astronomical Union. Symposium and published by Cambridge University Press. This book was released on 2009-04-16 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paradigm of a dark energy- and dark matter-dominated Universe, with the hierarchical merger scenario for the formation of galaxies, has scored impressive successes in matching the observed Universe. However, the theory fails to explain the difficulty in generating ordinary disk galaxies such as the Milky Way, suggesting that some important physics must be missing in current models. IAU Symposium 254 was organized to address this question, gathering researchers from an unusually broad range of fields, from cosmology to interstellar matter, and the formation and evolution of stars. High-class reviews, lectures and posters combine to define the frontiers in the field and point the way to new avenues of research. This volume presents a unique set of succinct overviews illuminating the full range of topics in this very active field. It also honors Danish astrophysicist Bengt Strömgren (1908-1987), who laid much of the foundation for this entire field.
Download or read book Journeys to the Ends of the Universe written by C.R. Kitchin and published by CRC Press. This book was released on 2023-07-14 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Journeys to the Ends of the Universe presents a tour through the universe from the big bang onward. The book explores the limits of knowledge where scientific fact overtakes and merges with the wilder speculations of science fiction. The beginnings of galaxies, stars, planets, and even life itself are related back to the raveled turmoil of the first few seconds and years of life in the cosmos. The journey continues past the ultimate fate of the solar system to probe the nature of supernovae. The future of galaxies, clusters of galaxies, super-clusters of clusters of galaxies, and so on leads toward the finale, where the author provides some bizarre musings of physicists and astronomers, suggesting possible destinies for the universe stretching its present age billions of times into the future.
