Book Description

The proceedings of MG16 give a broad view of all aspects of gravitational physics and astrophysics, from mathematical issues to recent observations and experiments. The scientific program of the meeting included 46 plenary presentations, 3 public lectures, 5 round tables and 81 parallel sessions arranged during the intense six-day online meeting. All talks were recorded and are available on the ICRANet YouTube channel at the following link: www.icranet.org/video_mg16.These proceedings are a representative sample of the very many contributions made at the meeting. They contain 383 papers, among which 14 come from the plenary sessions.The material represented in these proceedings cover the following topics: accretion, active galactic nuclei, alternative theories of gravity, black holes (theory, observations and experiments), binaries, boson stars, cosmic microwave background, cosmic strings, dark energy and large scale structure, dark matter, education, exact solutions, early universe, fundamental interactions and stellar evolution, fast transients, gravitational waves, high energy physics, history of relativity, neutron stars, precision tests, quantum gravity, strong fields, and white dwarf; all of them represented by a large number of contributions.The online e-proceedings are published in an open access format.




Connecting Quarks with the Cosmos


Book Description

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.




S.G.E.B. 2nd Edition


Book Description

The information age has begotten turmoil. It seems that the more information we have, the less peace the average person has. To many, as impression has developed that modern science has disproven the existence of the metaphysical realm, and doomed us to a sterile, pointless wandering in the widerness of minutiae. This couldn't be further from the truth! A reasonably skeptical look at modern philosophy, science, archeology and history point overwhelmingly in a single direction, and the truth that it points to is blissful and eternal.




Sterile Neutrino Dark Matter


Book Description

This book is a new look at one of the hottest topics in contemporary science, Dark Matter. It is the pioneering text dedicated to sterile neutrinos as candidate particles for Dark Matter, challenging some of the standard assumptions which may be true for some Dark Matter candidates but not for all. So, this can be seen either as an introduction to a specialized topic or an out-of-the-box introduction to the field of Dark Matter in general. No matter if you are a theoretical particle physicist, an observational astronomer, or a ground based experimentalist, no matter if you are a grad student or an active researcher, you can benefit from this text, for a simple reason: a non-standard candidate for Dark Matter can teach you a lot about what we truly know about our standard picture of how the Universe works.




New Worlds, New Horizons in Astronomy and Astrophysics


Book Description

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.




Modern Cosmology


Book Description

An advanced text for senior undergraduates, graduate students and physical scientists in fields outside cosmology. This is a self-contained book focusing on the linear theory of the evolution of density perturbations in the universe, and the anisotropiesin the cosmic microwave background.




Neutrino Cosmology


Book Description

A self-contained guide to the role played by neutrinos in the Universe and how their properties influence cosmological and astrophysical observations.










Matter in the Universe


Book Description

This volume, the fourteenth in the Space Sciences Series of ISS/, is dedicated to the matter in the universe, which was the topic of a workshop organized by ISSI from 19 to 22 March 2001 in Bern. The aim of the meeting was to gather ac tive researchers from various fields (cosmology, astrophysics, nuclear and particle physics as well as space science) to asses the exciting new developments in the search for abundant and yet unknown forms of matter in the universe. Due to the importance of the field and the rapid developments which are taking place ISSI decided to organize a workshop on matter in the universe and invited nine convenors, John Ellis, Johannes Geiss, Philippe Jetzer, Heinrich Leutwyler, Klaus Pretzl, Rafael Rebolo, Norbert Straumann, Gustav Andreas Tammann and Rudolf von Steiger, who formulated the aims and goals of the meeting. The work shop was organized such as to have only plenary sessions with typically half hour presentations and ample time for discussions. The last day was devoted to conclusions and future objectives. The knowledge of the amount and nature of matter present in the universe is undoubtedly one of the most relevant topics oftoday's astrophysics and cosmology.
