This second edition has been updated and substantially expanded. Starting with the description of our home galaxy, the Milky Way, this cogently written textbook introduces the reader to the astronomy of galaxies, their structure, active galactic nuclei, evolution and large scale distribution in the Universe. After an extensive and thorough introduction to modern observational and theoretical cosmology, the focus turns to the formation of structures and astronomical objects in the early Universe. The basics of classical astronomy and stellar astrophysics needed for extragalactic astronomy are provided in the appendix. While this book has grown out of introductory university courses on astronomy and astrophysics and includes a set of problems and solutions, it will not only benefit undergraduate students and lecturers; thanks to the comprehensive coverage of the field, even graduate students and researchers specializing in related fields will appreciate it as a valuable reference work.
Astronomy Methods is an introduction to basic practical tools, methods and phenomena that underlie quantitative astronomy. Taking a technical approach, the author covers a rich diversity of topics across all branches of astronomy, from radio to gamma-ray wavelengths. Clear, systematic presentations of the topics are accompanied by diagrams and problem sets. Written for undergraduates and graduate students, this book contains a wealth of information that is required for the practice and study of quantitative and analytical astronomy and astrophysics.

Discover a modern approach to the analysis, modeling and design of high sensitivity phased arrays. Network theory, numerical methods and computational electromagnetic simulation techniques are uniquely combined to enable full system analysis and design optimization. Beamforming and array signal processing theory are integrated into the treatment from the start. Digital signal processing methods such as polyphase filtering and RFI mitigation are described, along with technologies for real-time hardware implementation. Key concepts from interferometric imaging used in radio telescopes are also considered. A basic development of theory and modeling techniques is accompanied by problem sets that guide readers in developing modeling codes that retain the simplicity of the classical array factor method while incorporating mutual coupling effects and interactions between elements. Combining current research trends with pedagogical material suitable for a first-year graduate course, this is an invaluable resource for students, teachers, researchers, and practicing RF/microwave and antenna design engineers.
Selected Works of S Chandrasekhar (With Commentary)(In 2 Volumes)
Author: Kameshwar C Wali
Pubpsher: World Scientific
This invaluable book presents selected papers of S Chandrasekhar, co-winner of the Nobel Prize for Physics in 1983 and a scientific giant well known for his prolific and monumental contributions to astrophysics, physics and applied mathematics. The reader will find here most of Chandrasekhar's articles that led to major developments in various areas of physics and astrophysics. There are also articles of a popular and historical nature, as well as some hitherto unpublished material based on Chandrasekhar's talks at conferences. Each section of the book contains annotations by the editor. Contents: Volume 1:Early Years — The Theory of White Dwarfs and Stellar InteriorsRadiative Transfer, the Polarization of the Sunlit Sky, and the Negative Ion of HydrogenStochastic and Statistical Problems in AstronomyTurbulence and Hydromagnetic Problems in AstrophysicsHydrodynamic and Hydromagnetic StabilityVolume 2:Ellipsoidal Figures of EquilibriumRelativistic Instabilities and Post-Newtonian ApproximationsThe Mathematical Theory of Black Holes — Colliding WavesThe Nonradial Oscillations of Stars in General RelativityMiscellaneous Writings Readership: Researchers in astronomy, astrophysics and cosmology. Keywords:Astrophysics;Cosmology;Astrophysics;Astronomy;Physics;Applied MathematicsReviews: “It is a great pleasure to dip into Kameshwar Wali's rich selection from the works of the great Chandra, and to read Wali's illuminating comments. In addition to the seminal scientific papers, organized by subject, sometimes establishing whole fields of physics and astronomy, and almost bringing them to conclusion, the volumes include more than 300 pages of ‘semi-popular’ articles and talks (some previously unpublished), whose philosophical depth and beauty of expression would alone recommend these ‘selected works’.” Laurie M Brown Northwestern University “Apart from knowing the works of great scientists, students of science should also learn something about the creative process through which these scientists achieved them. In the case of Chandra, these papers give a glimpse into the mind of a highly methodical person who had identified his goals and worked hard and creatively to get there. For such readers Wali has done a commendable job, for which we should be thankful.” Professor Jayant V Narlikar The Inter University Centre for Astronomy and Astrophysics “… I am glad to find an opportunity to formulate an encouragement to proceed ahead with Chandra's legacy, and my faith in these new directions of astrophysical research. In forthcoming decades, these superb volumes of collected works ought to play an invaluable role.” Anne Magnon CUST-Blaise Pascal University “Wali's choices in these two volumes are a more selective and more interesting subset, picked as much to give a sense of the man as of the science … Chandra's celebrated Reviews of Modern Physics article ‘Stochastic Problems in Physics and Astronomy’ (1943) alone is worth the price of the volume … Fascinating also are the two 1953 papers by Chandra and Enrico Fermi, the writing of which Chandra later remembered as one of the most exciting experiences of his scientific career.” Physics Today “The latter topic contains some fascinating essays and accounts of interdisciplinary lectures.” Mathematical Reviews

In the past one hundred years, two major realities have changed both science and religion. The world of science has been enriched by quantum physics, the computation of the age of the universe, archaeological data in the Middle East, and a scientific stress on historical writing. The world of religion has been enriched by the establishment of the World Council of Churches and the Second Vatican Council. In the past fifty years, major scientists and major religious leaders have met together again and again. In the past fifty years, religious leaders from Christianity, Islam, and Judaism have held a number of thought-provoking conferences. In this volume, these gatherings are reviewed and evaluated. Two major religious problems have challenged the science-religion discussions, namely, which God should the scientists agree on, the Trinitarian God, Allah, or Yahweh? Which history of the universe sponsored by these three religions should scientists be looking for? This volume raises questions and suggests some preliminary forms of serious discussion.
