Book Description
This book provides an explanation of electromagnetic scattering effects in the intergalactic medium that produce what have been misinterpreted as 'evolutionary' effects. It accounts for a variety of cosmological phenomena from spectroscopic redshifts to microwave background radiation. These have variously been attributed by the standard cosmological model to an origin in a 'big bang', 'dark matter', and mysterious 'vacuum energy'. This scattering model provides a viable stationary state alternative to the established view of the universe with predictions that more precisely match observation without ad hoc assumptions.

Book Description
The classic introduction to physical cosmology from Nobel Prize–winning physicist P. J. E. Peebles Principles of Physical Cosmology is the essential introduction to this critical area of modern physics, written by a leading pioneer who has shaped the course of the field for decades. P. J. E. Peebles provides an authoritative overview of the field, showing how observation has combined with theory to establish the science of physical cosmology. He presents the elements of physical cosmology, including the history of the discovery of the expanding universe; surveys the cosmological tests that measure the geometry of space-time, with a discussion of general relativity as the basis for these tests; and reviews the origin of galaxies and the large-scale structure of the universe. Now featuring Peebles's 2019 Nobel lecture, Principles of Physical Cosmology remains an indispensable reference for students and researchers alike.

Book Description
The first part of the work presents the elements of physical cosmology, including the history of the discovery of the expanding universe. The second part, on the cosmological tests that measure the geometry of spacetime, discusses general relativity theory as the basis for the tests, and then surveys the broad variety of ways the tests can be applied with the new generations of telescopes and detectors. The third part deals with the origin of galaxies and the large-scale structure of the universe, and reviews ideas about how the evolution of the universe might be traced back to very early epochs when structure originated. Each chapter begins with an introduction that can be understood with no special knowledge beyond undergraduate physics, and then progresses to more specialized topics.

Book Description
The dawn of the first stars, galaxies and black holes signaled a fundamental milestone in our Universe’s evolution: the Epoch of Reionization. The light from these galactic ancestors began spreading out, ionizing virtually every atom in existence. Our Universe transitioned from darkness to light, from cold to hot, from simple and boring to the wondrous cosmic zoo we see around us today. Despite its importance, observations of reionization have been few, and their interpretation has been highly controversial. Fortunately, this is rapidly changing. We will soon enter the "Big Data” era of this mysterious epoch, driven by an upcoming wave of observations with state-of-the-art telescopes as well as new sophisticated analysis tools. The aim of this volume is to summarize the current status and future outlook of the reionization field. We bring together leading experts in many sub-disciplines, highlighting the measurements that will illuminate our understanding of reionization and the cosmic dawn: (i) 21cm interferometry; (ii) high-redshift quasar spectra; (iii) high-redshift galaxy surveys; (iv) primary and secondary anisotropies of the Cosmic Microwave Background; (v) high-resolution studies of the metal content of early galaxies. We seek a roadmap to interpreting the wealth of upcoming observations. What is the best use of limited observational resources? How do we develop theoretical tools tailored for each observation? Ultimately, what will we learn about the epoch of reionization and our galactic ancestors?

Book Description
This special issue of the international journal of cosmic physics, Astrophysics and Space Science, contains invited contributions delivered at the Second IEEE International Workshop on Plasma Astrophysics and Cosmology, held from 10 to 12 May 1993 in Princeton, New Jersey. The Workshop was sponsored by the NSF Division of Atmospheric Sciences, NASA Headquarters, Space Physics Division, and the Nuclear and Plasma Sciences Society of the Institute of Electrical and Electronics Engineers. It was the purpose of the Workshop to update topics in Plasma Astrophysics and Cosmology presented at the First IEEE International Workshop on Plasma Cosmology, La Jolla, California, 20-22 February 1989, and to again bring together observers and theorists to discuss the related links between plasma theory and observation. Another goal of the Workshop and these proceedings was to highlight the Centennial Celebration (1896-1996) of the founding of Plasma Astrophysics and Cosmology and several papers are devoted to the history of this field of science.

Book Description
The hydrogen Lyman-alpha line is of utmost importance to many fields of astrophysics. This UV line being conveniently redshifted with distance to the visible and even near infrared wavelength ranges, it is observable from the ground, and provides the main observational window on the formation and evolution of high redshift galaxies. Absorbing systems that would otherwise go unnoticed are revealed through the Lyman-alpha forest, Lyman-limit, and damped Lyman-alpha systems, tracing the distribution of baryonic matter on large scales, and its chemical enrichment. We are living an exciting epoch with the advent of new instruments and facilities, on board of satellites and on the ground. Wide field and very sensitive integral field spectrographs are becoming available on the ground, such as MUSE at the ESO VLT. The giant E-ELT and TMT telescopes will foster a quantum leap in sensitivity and both spatial and spectroscopic resolution, to the point of being able, perhaps, to measure directly the acceleration of the Hubble flow. In space, the JWST will open new possibilities to study the Lyman-alpha emission of primordial galaxies in the near infrared. As long as the Hubble Space Telescope will remain available, the UV-restframe properties of nearby galaxies will be accessible to our knowledge. Therefore, this Saas-Fee course appears very timely and should meet the interest of many young researchers.
