Available in PDF, EPUB and Kindle. Book excerpt: The workshop brought together experts in astronomy and particle physics to make the science case for a satellite mission to measure the polarization of the cosmic microwave background (CMB). Detailed maps of the CMB polarization will potentially reveal clues about the origin of the universe. An early epoch of inflation typically produces a spectrum of gravitational waves and these leave a distinctive imprint on the CMB polarization field. The workshop addressed all theoretical aspects of this science: which inflationary models predict an amplitude that will be detected and which do not? What do alternatives to inflation predict? Apart from the gravitational wave signal, what other science can be gleaned from these measurements? High resolution maps should have traces of gravitational lensing which in turn is affected by dark energy and massive neutrinos. How well will a satellite mission be able to measure these effects? CMB polarization also speaks to the end of the Dark Ages; the constraints on reionzation are discussed in the context of all other probes. Finally, several articles – based on many talks and follow-up work – probe the science of and removal of Galactic foregrounds.

Book excerpt: This book contains written versions of the presentations made at the 4th International Workshop on the Identification of Dark Matter (IDM 2002), held in York, UK, in September 2002. The objective of this workshop series is to assess the status of work attempting to identify what constitutes dark matter OCo in particular, to consider the techniques being used, how successful they are, and what new techniques are likely to improve prospects for identifying likely dark matter candidates in the future. At IDM 2002 special emphasis was placed on recent results obtained in searches for baryonic and non-baryonic dark matter. The proceedings include reviews of major topics on dark matter, as well as short contributed talks."

Download or read book Cryocoolers written by Milind D. Atrey and published by Springer Nature. This book was released on 2020-02-24 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book serves as an introduction to cryocooler technology and describes the principle applications of cryocoolers across a broad range of fields. It covers the specific requirements of these applications, and describes how the advantages and disadvantages of different cryocooler systems are taken into consideration. For example, Stirling coolers tend to be used only in space applications because of their high coefficient of performance, low weight and proven reliability, whilst Gifford-McMahon coolers are used for ground applications, such as in cryopumps and MRI shield cooling applications. Joule-Thomson cryocoolers are used in missile technology because of the fast cool down requirements. The cryocooler field is fast developing and the number of applications are growing because of the increasing costs of the cryogens such as Helium and Neon. The first chapter of the book introduces the different types of cryocoolers, their classification, working principles, and their design aspects, and briefly mentions some of the applications of these systems. This introductory chapter is followed by a number of contributions from prominent international researchers, each describing a specific field of application, the cooling requirements and the cryocooler systems employed. These areas of application include gas liquefaction, space technology, medical science, dilution refrigerators, missile systems, and physics research including particle accelerators. Each chapter describes the cooling requirements based on the end use, the approximate cooling load calculations, the criteria for cryocooler selection, the arrangement for cryocooler placement, the connection of the cooler to the object to be cooled, and includes genuine case studies. Intended primarily for researchers working on cryocoolers, the book will also serve as an introduction to cryocooler technology for students, and a useful reference for those using cryocooler systems in any area of application.

This book was released on 1998-09-22 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deciphering the script for the Big Bang has now become a joint effort of particle physicists and cosmologists. The origin and first moments of the early Universe were determined by the same fundamental processes which are studied in terrestrial accelerators and whose traces from the early Universe can be seen in astrophysical observations. It is now almost universally accepted that most of the debris left over from the Big Bang is likely to be in the form of particle dark matter. Identifying its nature and measuring its abundance in the Universe have become major goals of theorists and experimentalists alike. This volume reviews the progress made at the frontiers of research in these rapidly expanding fields. A broad range of topics, from inflation to primordial black holes to physics at the Planck era, and to dark matter and neutrinos — both reviews and reports on the most recent advances — is presented by leaders in the field.

This book was released on 1998-08-08 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the largest physical structures in the universe is essential for the comprehension of the cosmos as a whole. We want to know how our world is formed, what it is made of and how it evolves.Galaxies, as the most visible constituents of the universe, are interesting probes for the cosmic time sequence. Their formation and development provides us with unique clues to the cosmic evolution. This is tightly connected with the hierarchical cosmic structure: groups and clusters of galaxies and their embedding into the large scale structure offer the opportunity to study the dependencies.Galaxy redshift surveys delineate most impressively a large cosmic web, which is composed of sheets and filaments. Grand simulations of the cosmic evolution complement these observations from the theoretical side and allow one quantify and compare various model universes.Quasar absorption line studies, gravitational lensing and even the X-ray background radiation provide important quantitative measures of the history of matter clustering. Finally, the microwave radiation traces very early structures, which are supposed to originate in the phase of inflationary expansion shortly after the big bang.This volume constituting the proceedings of the 12th Potsdam Cosmology Workshop, deals with the basic aspects of cosmological structure formation on the largest physical scales.
