This book was released on 2016-09-06 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Searching for Dark Matter with Cosmic Gamma Rays summarizes the evidence for dark matter and what we can learn about its particle nature using cosmic gamma rays. It has almost been 100 years since Fritz Zwicky first detected hints that most of the matter in the Universe that doesn't directly emit or reflect light. Since then, the observational evidence for dark matter has continued to grow. Dark matter may be a new kind of particle that is governed by physics beyond our Standard Model of particle physics. In many models, dark matter annihilation or decay produces gamma rays. There are a variety of instruments observing the gamma-ray sky from tens of MeV to hundreds of TeV. Some make deep, focused observations of small regions, while others provide coverage of the entire sky. Each experiment offers complementary sensitivity to dark matter searches in a variety of target sizes, locations, and dark matter mass scales. We review results from recent gamma-ray experiments including anomalies some have attributed to dark matter. We also discuss how our gamma-ray observations complement other dark matter searches and the prospects for future experiments.

Download or read book Our Universe Via Drexler Dark Matter written by Jerome Drexler and published by Universal-Publishers. This book was released on 2009 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is different from all other modern cosmology books in several ways. It introduces a cosmologic universe, which is orderly, logical, and systematic. It teaches and explains by illustrating how a variety of cosmic mysteries have been solved. It raises the status of dark matter in the universe by illuminating its roles as the principal source of energy, the principal source of matter in the form of hydrogen and helium, and the principal source of cosmic relationships with the principal cosmic phenomena of the universe. This book simplifies the universe as Nicolaus Copernicus' book simplified the solar system in 1543. With more and more cosmic mysteries being discovered and the slow progress in solving them, cosmologists and astrophysicists must re-train themselves to understand and to utilize the postmodern unified astrophysical cosmology model and to maximize the knowledge derived from the astronomical data. These are the three principal objectives of this book.

Available in PDF, EPUB and Kindle. Book excerpt: Advances made by physicists in understanding matter, space, and time and by astronomers in understanding the universe as a whole have closely intertwined the question being asked about the universe at its two extremesâ€"the very large and the very small. This report identifies 11 key questions that have a good chance to be answered in the next decade. It urges that a new research strategy be created that brings to bear the techniques of both astronomy and sub-atomic physics in a cross-disciplinary way to address these questions. The report presents seven recommendations to facilitate the necessary research and development coordination. These recommendations identify key priorities for future scientific projects critical for realizing these scientific opportunities.

Available in PDF, EPUB and Kindle. Book excerpt: What’s in the dark? Countless generations have gazed up at the night sky and asked this question—the same question that cosmologists ask themselves as they study the universe. The answer turns out to be surprising and rich. The space between stars is filled with an exotic substance called “dark matter” that exerts gravity but does not emit, absorb, or reflect light. The space between galaxies is rife with “dark energy” that creates a sort of cosmic antigravity causing the expansion of the universe to accelerate. Together, dark matter and dark energy account for 95 percent of the content of the universe. News reporters and science journalists routinely talk about these findings using terms that they assume we have a working knowledge of, but do you really understand how astronomers arrive at their findings or what it all means? Cosmologists face a conundrum: how can we study substances we cannot see, let alone manipulate? A powerful approach is to observe objects whose motion is influenced by gravity. Einstein predicted that gravity can act like a lens to bend light. Today we see hundreds of cases of this—instances where the gravity of a distant galaxy distorts our view of a more distant object, creating multiple images or spectacular arcs on the sky. Gravitational lensing is now a key part of the international quest to understand the invisible substance that surrounds us, penetrates us, and binds the universe together. A Ray of Light in a Sea of Dark Matter offers readers a concise, accessible explanation of how astronomers probe dark matter. Readers quickly gain an understanding of what might be out there, how scientists arrive at their findings, and why this research is important to us. Engaging and insightful, Charles Keeton gives everyone an opportunity to be an active learner and listener in our ever-expanding universe. Watch a video with Charles Keeton: Watch video now.

Download or read book Discovering Postmodern Cosmology written by Jerome Drexler and published by Universal-Publishers. This book was released on 2008 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learn how a world-class inventor-scientist is currently tackling the greatest scientific mysteries of the universe -- and succeeding. With his new book, Drexler provides a viable baseline to jump-start debate on a standard model for postmodern cosmology. It is the first book to not only address these seven unsolved cosmic mysteries, shown in this book's subtitle, but also offer plausible explanations for each of them. The correlation of these seven cosmic phenomena by Drexler offers a revolutionary advance in cosmological research and potentially broad acceptance and use of the related concepts. This book was written for open-minded cosmologists, astronomers, astrophysicists, physicists, engineers, students, enthusiasts and those at NASA, NSF, DOE and ESO who want to understand postmodern cosmology. The author's five years of cosmology research, and his successes, convinced him that his postmodern cosmology model is correctly based upon the relationships and linkages of these seven cosmic phenomena.

Download or read book How Dark Matter Created Dark Energy and the Sun written by Jerome Drexler and published by Universal-Publishers. This book was released on 2004 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through use of a lecture-slide format, this book presents an astrophysics detective story that chronicles Jerome Drexler's literature search for astronomical clues and evidence to unveil the nature of dark matter. There are a number of mysteries in astrophysics and cosmology that have remained unsolved for decades. What is dark matter? How exactly are stars created? In 1998, it was determined from supernova studies that the expansion of the Universe was accelerating, thereby creating the mystery of dark energy. Astrophysicists have developed mutually exclusive, single-phenomenon theories for each of these three phenomena, but not a unified theory for all three of them. The author's original goal was to identify dark matter, a decades-old mystery. In the process, he developed a new theory for dark matter and illuminated the nature of dark energy and the process of Sun formation. Since dark matter may have been instrumental in the creation of galaxies and stars, the author decided to test his new dark matter theory on the formation of the Sun. The results were very encouraging. He next sought a possible link between dark matter and the accelerating expansion of the Universe, which is attributed to the mysterious dark energy. Using his dark matter theory and the laws of physics, the author explained the accelerating expansion of the Universe in a plausible manner. This book chronicles the author's search for a unified astrophysical theory and how it finally evolved.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together reviews from leading international authorities on the developments in the study of dark matter and dark energy, as seen from both their cosmological and particle physics side. Studying the physical and astrophysical properties of the dark components of our Universe is a crucial step towards the ultimate goal of unveiling their nature. The work developed from a doctoral school sponsored by the Italian Society of General Relativity and Gravitation. The book starts with a concise introduction to the standard cosmological model, as well as with a presentation of the theory of linear perturbations around a homogeneous and isotropic background. It covers the particle physics and cosmological aspects of dark matter and (dynamical) dark energy, including a discussion of how modified theories of gravity could provide a possible candidate for dark energy. A detailed presentation is also given of the possible ways of testing the theory in terms of cosmic microwave background, galaxy redshift surveys and weak gravitational lensing observations. Included is a chapter reviewing extensively the direct and indirect methods of detection of the hypothetical dark matter particles. Also included is a self-contained introduction to the techniques and most important results of numerical (e.g. N-body) simulations in cosmology. " This volume will be useful to researchers, PhD and graduate students in Astrophysics, Cosmology Physics and Mathematics, who are interested in cosmology, dark matter and dark energy.

Book excerpt: This book presents several new, important explanations for dark matter, all dissimilar to the discredited subatomic particle-like but invisible matter. One chapter presents evidence that abundant cold hydrogen, baryonic matter, is the source of the missing gravity. Another chapter suggests that dark matter is better explained by stars in spiral galaxies that follow non-Keplerian orbits. A third chapter proposes that gravity attributed to dark matter is due to the sprinkling of black holes throughout galaxies, which is supported by LIGO/Virgo observations. Another chapter questions the assumptions of the Friedmann (FLRW) model, proposing a better method for handling astrophysical data. Additional chapters discuss cosmic ray propagation, axion decay, the cosmological scale factor, and the philosophical outlook of cosmologists when dealing with the questions of dark matter and dark energy.
