Available in PDF, EPUB and Kindle. Book excerpt: In its fiscal year 2002 budget summary document the Bush administration expressed concern-based in part on the findings and conclusions of two National Research Council studies-about recent trends in the federal funding of astronomy and astrophysics research. The President's budget blueprint suggested that now is the time to address these concerns and directed the National Science Foundation (NSF) and the National Aeronautics and Space Administration (NASA) to establish a blue ribbon panel to (1) assess the organizational effectiveness of the federal research enterprise in astronomy and astrophysics, (2) consider the pros and cons of transferring NSF's astronomy responsibilities to NASA, and (3) suggest alternative options for addressing issues in the management and organization of astronomical and astrophysical research. NASA and NSF asked the National Research Council to carry out the rapid assessment requested by the President. This report, focusing on the roles of NSF and NASA, provides the results of that assessment.

Download or read book New Worlds New Horizons in Astronomy and Astrophysics written by National Research Council and published by National Academies Press. This book was released on 2011-02-04 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Driven by discoveries, and enabled by leaps in technology and imagination, our understanding of the universe has changed dramatically during the course of the last few decades. The fields of astronomy and astrophysics are making new connections to physics, chemistry, biology, and computer science. Based on a broad and comprehensive survey of scientific opportunities, infrastructure, and organization in a national and international context, New Worlds, New Horizons in Astronomy and Astrophysics outlines a plan for ground- and space- based astronomy and astrophysics for the decade of the 2010's. Realizing these scientific opportunities is contingent upon maintaining and strengthening the foundations of the research enterprise including technological development, theory, computation and data handling, laboratory experiments, and human resources. New Worlds, New Horizons in Astronomy and Astrophysics proposes enhancing innovative but moderate-cost programs in space and on the ground that will enable the community to respond rapidly and flexibly to new scientific discoveries. The book recommends beginning construction on survey telescopes in space and on the ground to investigate the nature of dark energy, as well as the next generation of large ground-based giant optical telescopes and a new class of space-based gravitational observatory to observe the merging of distant black holes and precisely test theories of gravity. New Worlds, New Horizons in Astronomy and Astrophysics recommends a balanced and executable program that will support research surrounding the most profound questions about the cosmos. The discoveries ahead will facilitate the search for habitable planets, shed light on dark energy and dark matter, and aid our understanding of the history of the universe and how the earliest stars and galaxies formed. The book is a useful resource for agencies supporting the field of astronomy and astrophysics, the Congressional committees with jurisdiction over those agencies, the scientific community, and the public.

Download or read book Observational Astrophysics written by Pierre Lena and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the last twenty years astronomy has been developing dramatically. Until the nineteen-fifties, telescopes, spectrometers, and photographic plates consti tuted a relatively simple set of tools which had been refined to a high degree of perfection by the joint efforts of physicists and astronomers. Indeed these tools helped at the birth of modern astrophysics: the discovery of the expan sion of the Universe. Then came radioastronomy and the advent of electronics; the last thirty years have seen the application to astrophysics of a wealth of new experimental techniques, based on the most advanced fields of physics, and a constant interchange of ideas between physicists and astronomers. Last, but not least, modern computers have sharply reduced the burden of dealing with the information painfully extracted from the skies, whether from ever scarce photons, or from the gigantic data flows provided by satellites and large telescopes. The aim of this book is not to give an extensive overview of all the tech niques currently in use in astronomy, nor to provide detailed instructions for preparing or carrying out an astronomical project. Its purpose is methodologi cal: photons are still the main carriers of information between celestial sources and the observer. How we are to collect, sample, measure, and store this infor mation is the unifying theme of the book. Rather than the diversity of tech niques appropriate for each wavelength range, we emphasize the physical and mathematical bases which are common to all wavelength regimes.
Download or read book Experimental Astrophysics written by BATTISTELLI and published by Iph003. This book was released on 2021 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are now living in the multimessenger era in which often weak and elusive astrophysical phenomena need to be studied using different and orthogonal probes and information carriers in order to be fully understood. Different techniques need to be emploted and developped to detect and carefuly characterize electromagnetic waves arising from astrophysical obsjects depending mainly on their energy and other characteristics, such as spectral features and polarization. This book is designed to give advanced undergraduate students a description of the most popular techniques and instrumentation employed in modern astrophysics. Focusing on electromagnetic radiation and its detection spanning from radio- to X-ray wavelengths, it gives a general description of astrophysical observables, such as flux, brightness, throughput, and magnitude. It describes general concepts about geometrical and physical optics at different wavelengths, in an astronomical context, including the concepts of lenses, mirrors, antennas, telescopes, the focal plane, angular resolution, the field of view, and the diffraction limit. The origin of noise and the extraction of a signal from it is also covered, including noise reduction techniques such as filtering, amplification, as well as cryogenic techniques. The theory of signals and the theorems related to digital electronics are also introduced. A set of student laboratory activities is included to illustrate the concepts covered in the book.

Available in PDF, EPUB and Kindle. Book excerpt: Written by one of today’s most highly respected astrophysicists, Foundations of High-Energy Astrophysics is an introduction to the mathematical and physical techniques used in the study of high-energy astrophysics. Here, Mario Vietri approaches the basics of high-energy astrophysics with an emphasis on underlying physical processes as opposed to a more mathematical approach. Alongside more traditional topics, Vietri presents new subjects increasingly considered crucial to understanding high-energy astrophysical sources, including the electrodynamics of cosmic sources, new developments in the theory of standard accretion disks, and the physics of coronae, thick disks, and accretion onto magnetized objects. The most thorough and engaging survey of high-energy astrophysics available today, Foundations of High-Energy Astrophysics introduces the main physical processes relevant to the field in a rigorous yet accessible way, while paying careful attention to observational issues. Vietri’s book will quickly become a classic text for students and active researchers in astronomy and astrophysics. Those in adjoining fields will also find it a valuable addition to their personal libraries.

Book excerpt: Evaluation of the Implementation of WFIRST in the Context of New Worlds, New Horizons in Astronomy and Astrophysics assesses whether the proposed Astrophysics Focused Telescope Assets (AFTA) design reference mission described in the April 30, 2013 report of the AFTA Science Definition Team (SDT), WFIRST-2.4, is responsive to the overall strategy to pursue the science objectives of New Worlds, New Horizons in Astronomy and Astrophysics, and in particular, the survey's top ranked, large-scale, space-based priority: the Wide Field Infrared Survey Telescope (WFIRST). This report considers the versions of WFIRST-2.4 with and without the coronagraph, as described in the AFTA SDT report. The report compares the WFIRST mission described in New Worlds, New Horizons to the AFTA SDT WFIRST-2.4 design reference mission, with and without the coronagraph, on the basis of their science objectives, technical complexity, and programmatic rationale, including projected cost. This report gives an overview of relevant scientific, technical, and programmatic changes that have occurred since the release of New Worlds, New Horizons, and assesses the responsiveness of the WFIRST mission to the science and technology objectives of the New Worlds report.
Download or read book Principles of Astrophysics written by Charles Keeton and published by Springer. This book was released on 2014-05-10 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a survey of astrophysics at the advanced undergraduate level, providing a physics-centred analysis of a broad range of astronomical systems. It originates from a two-semester course sequence at Rutgers University that is meant to appeal not only to astrophysics students but also more broadly to physics and engineering students. The organisation is driven more by physics than by astronomy; in other words, topics are first developed in physics and then applied to astronomical systems that can be investigated, rather than the other way around. The first half of the book focuses on gravity. The theme in this part of the book, as well as throughout astrophysics, is using motion to investigate mass. The goal of Chapters 2-11 is to develop a progressively richer understanding of gravity as it applies to objects ranging from planets and moons to galaxies and the universe as a whole. The second half uses other aspects of physics to address one of the big questions. While “Why are we here?” lies beyond the realm of physics, a closely related question is within our reach: “How did we get here?” The goal of Chapters 12-20 is to understand the physics behind the remarkable story of how the Universe, Earth and life were formed. This book assumes familiarity with vector calculus and introductory physics (mechanics, electromagnetism, gas physics and atomic physics); however, all of the physics topics are reviewed as they come up (and vital aspects of vector calculus are reviewed in the Appendix).

Book excerpt: Essential Astrophysics is a book to learn or teach from, as well as a fundamental reference volume for anyone interested in astronomy and astrophysics. It presents astrophysics from basic principles without requiring any previous study of astronomy or astrophysics. It serves as a comprehensive introductory text, which takes the student through the field of astrophysics in lecture-sized chapters of basic physical principles applied to the cosmos. This one-semester overview will be enjoyed by undergraduate students with an interest in the physical sciences, such as astronomy, chemistry, engineering or physics, as well as by any curious student interested in learning about our celestial science. The mathematics required for understanding the text is on the level of simple algebra, for that is all that is needed to describe the fundamental principles. The text is of sufficient breadth and depth to prepare the interested student for more advanced specialised courses in the future. Astronomical examples are provided throughout the text, to reinforce the basic concepts and physics, and to demonstrate the use of the relevant formulae. In this way, the student learns to apply the fundamental equations and principles to cosmic objects and situations. Astronomical and physical constants and units as well as the most fundamental equations can be found in the appendix. Essential Astrophysics goes beyond the typical textbook by including references to the seminal papers in the field, with further reference to recent applications, results, or specialised literature.
