Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, we describe observational and theoretical work related to the large-scale clustering of matter in the universe. Such work is crucial in constraining models of the Universe in future surveys and is one of the most powerful probes of the nature of dark energy. In Chapter \ref{magnification}, we present work performed using the Deep Lens Survey (DLS) to measure the growth of structure over cosmic time using weak lensing magnification. This is the first time such a measurement has been performed and represents a significant step forward for this relatively new probe of large-scale structure (LSS) which is known to be complementary to other weak lensing measurements. Later in Chapter \ref{conclusions}, we discuss steps needed for magnification become a competitive, precision probe of cosmology. Chapter \ref{covariance} presents a model for the emulation cosmology dependent error covariances in LSS probes. Estimating these covariances are necessary in order to compare models to the data and require a large amount of computational time to create the simulations required. Tools to reduce the number of simulations required and model the cosmology dependence are needed. We utilize a novel decomposition of LSS error covariances that allows for construction of a emulator that fulfills both of these criteria. In order for future surveys to reach their goals, methods to model measurement error and new probes of LSS complementary to those planned are required.The conclusions of this dissertation in Chapter \ref{conclusions} address the future outlook for this work and research that must be done between now and when the next set of survey data is available. Many systematic errors need to be addressed in magnification before it can be considered a precision cosmology tool. For the error covariances, additional methods to reduce the required number of simulations to estimate the matrices are required. In the Appendix, we present a high level description of an open sourced software package that we developed and implemented over the course of these two projects.
Download or read book Measurement Standards Variability in the Universe Modeling written by Vitaly Groppen and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first work which discusses an approach for the study of universe simulators based on the idea of measurement standards variability. This approach permits us to develop free of contradictions simulators of the universe, describing the Hubble law, red shifts' independence on wavelength, "tired light" effect and some others as manifestations of measurement standards variability. Studies using this approach seem to show that the universe in terms of the radial velocities of galaxies seems to be more stable than it is believed today. Experiments reflect the efforts to verify the efficiency of this approach for creation of simulators, describing macro and micro components of the universe. Results of experiments convince of the correctness of the proposed models.

Download or read book Redefining Standard Model Cosmology written by Brian Albert Robson and published by BoD – Books on Demand. This book was released on 2019-06-12 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current standard model of cosmology is based primarily on two incompatible theoretical models: (1) the standard model of particle physics, which describes the physics of the very small in terms of quantum mechanics, and (2) the general theory of relativity, which describes the physics of the very large in terms of classical physics. Both these theoretical models are considered to be incomplete in the sense that they do not provide any understanding of several empirical observations, such as the Big Bang, dark matter, dark energy, gravity, and matter-antimatter asymmetry in the universe. The main aim of this book is to discuss these serious problems that threaten to undermine the current standard model of cosmology.
Download or read book Ultimate Explanations of the Universe written by Michael Heller and published by Springer Science & Business Media. This book was released on 2009-11-12 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: We humans are collectively driven by a powerful - yet not fully explained - instinct to understand. We would like to see everything established, proven, laid bare. The more important an issue, the more we desire to see it clarified, stripped of all secrets, all shades of gray. What could be more important than to understand the Universe and ourselves as a part of it? To find a window onto our origin and our destiny? This book examines how far our modern cosmological theories - with their sometimes audacious models, such as inflation, cyclic histories, quantum creation, parallel universes - can take us towards answering these questions. Can such theories lead us to ultimate truths, leaving nothing unexplained? Last, but not least, Heller addresses the thorny problem of why and whether we should expect to find theories with all-encompassing explicative power.

Book excerpt: Imagination and science take flight in this new description of our three dimensional universe. The old physics of equations and non-answers is replaced with mechanisms that explain reality. The fundamental particle of matter is modeled and mechanisms for the properties of matter emerge. Our journey takes the reader from a description of matter to the birth and death of our universe. The story delivers a visual explanation for the mechanisms that make our universe work. Charge, inertial mass, gravity and the Double Slit experiment are explained as never before. This new theory of matter generates novel interpretations for cosmological observations. Direct English is used with macro world analogues and visual images to describe natural phenomena. Our universe becomes comprehensible when the dance of matter and energy is for a first time explained. Dark energy, dark matter and the measurement problem are explained. Courage is a requisite for looking deeply into our universe but there is grandeur in this view.

Book excerpt: The lectures that four authors present in this volume investigate core topics related to the accelerated expansion of the Universe. Accelerated expansion occured in the ?36 very early Universe – an exponential expansion in the in ationary period 10 s after the Big Bang. This well-established theoretical concept had rst been p- posed in 1980 by Alan Guth to account for the homogeneity and isotropy of the observable universe, and simultaneously by Alexei Starobinski, and has since then been developed by many authors in great theoretical detail.
