Book excerpt: The first observation of the Cosmic Microwave Background anisotropies in 1992 ushered in the era of precision cosmology, giving us a glimpse of the Universe380,000 years after the Big Bang. New CMB results from the Planck satellite haveprovided the most sensitive full-sky observations to date. In one of their first-yearpapers, the Planck collaboration confirmed a lack of correlation in the temperaturefluctuations at the largest angles on the sky. The feature had previously been shownto be statistically significant with WMAP data sets, and the feature cannot be explained by a mechanism within our current understanding of LambdaCDM cosmology. To push forward the knowledge of our Universe and to explain the large-anglebehavior that we observe, we must identify new areas of cosmology, outside oftemperature fluctuations alone, that shed new light on physics at large scales. Tothat end, we investigate the two-point correlation functions of CMB polarizationand temperature-lensing correlations as independent probes of new physics thatmay be the root of the temperature correlation suppression. We evaluate the correlation functions for the standard LambdaCDM cosmology constrained by the observedtemperature correlation function, and compute statistics characterizing their suppression on large angular scales. Future full-sky polarization and lensing fieldmaps with minimal systematic errors on large angular scales will provide strongtests of whether the observed temperature correlation function is a statistical flukeor reflects a fundamental shortcoming of the standard cosmological model.

Available in PDF, EPUB and Kindle. Book excerpt: An epic, full-color visual journey through all scales of the universe In The Zoomable Universe, the award-winning astrobiologist Caleb Scharf and the acclaimed artist Ron Miller take us on an epic tour through all known scales of reality, from the largest possible magnitude to the smallest. Drawing on cutting-edge science, they begin at the limits of the observable universe, a scale spanning 10^27 meters—about 93 billion light-years. And they end in the subatomic realm, at 10^-35 meters, where the fabric of space-time itself confounds all known rules of physics. In between are galaxies, stars and planets, oceans and continents, plants and animals, microorganisms, atoms, and much, much more. Stops along the way—all enlivened by Scharf’s sparkling prose and his original insights into the nature of our universe—include the brilliant core of the Milky Way, the surface of a rogue planet, the back of an elephant, and a sea of jostling quarks. The Zoomable Universe is packed with more than 100 original illustrations and infographics that will captivate readers of every age. It is a whimsical celebration of discovery, a testament to our astounding ability to see beyond our own vantage point and chart a course from the farthest reaches of the cosmos to its subatomic depths—in short, a must-have for the shelves of all explorers.

Download or read book The Large scale Structure of the Universe written by Phillip James Edwin Peebles and published by . This book was released on 1980 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Opinions on the large-scale structure of the early universe range widely from primeval chaos to a well-ordered mass distribution. P.J.E. Peebles argues that the evolution proceeded from a nearly uniform initial state to a progressively more irregular and clumpy universe. The discussion centers on the largest known structures, the clusters of galaxies, the empirical evidence of the nature of the clustering, and the theories of how the clustering evolves in an expanding universe. In Chapter One the author provides an historical introduction to the subject. Chapter Two contains a survey of methods used to deal with the Newtonian approximation to the theory of the evolution of the mass distribution. Recent progress in the use of statistical measures of the clustering is described in Chapter Three. Chapters Four and Five return to techniques for dealing with cosmic evolution, in the statistical measures of clustering and under general relativity theory. Lastly, in Chapter Six Professor Peebles assesses the progress in attempts to link theory and observation to arrive at a well established physical picture of the nature and evolution of the universe.

This book was released on 2012-12-06 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third Advanced Study Institute (ASI) on Techniques and Concepts of High Energy Physics was held at the Hotel on the Cay, in the scenic harbor of Christiansted, St. Croix, U. S. Virgin Islands. Christiansted was the site of the first ASI, and it was certainly a delight to return there again. As in the previous ASI's, the aim was to bring together a small group of promising young experimenters and several outstanding senior scholars in experimental and theoretical high energy physics in order to learn about the latest developments in the field and to strengthen contacts among scientists from different countries and different backgrounds. The institute was both a great scientific and a great social success; much of this was due to the beautiful setting and to the dedication of the Hotel management of Ray Boudreau and Hurchell Greenaway and their excellent staff. The primary support for the meeting was once again provided by the Scientific Affairs Division of NATO. The ASI was cosponsored by the U. S. Department of Energy, by Fermilab, by the National Science Found ation, and by the University of Rochester. A special contribution from the Oliver S. and Jennie R. Donaldson Charitable Trust provided an important degree of flexibility, as well as support for worthy students from developing nations. As in the case of the previous ASI's, the scientific program was designed for advanced graduate students and recent PhD recipients in experimental particle physics.
