With a focus on modified gravity this book presents a review of the recent developments in the fields of gravity and cosmology, presenting the state of the art, high-lighting the open problems, and outlining the directions of future research. General Relativity and the ΛCDM framework are currently the standard lore and constitute the concordance paradigm of cosmology. Nevertheless, long-standing open theoretical issues, as well as possible new observational ones arising from the explosive development of cosmology in the last two decades, offer the motivation and lead a large amount of research to be devoted in constructing various extensions and modifications. In this review all extended theories and scenarios are first examined under the light of theoretical consistency, and are then applied in various geometrical backgrounds, such as the cosmological and the spherical symmetric ones. Their predictions at both the background and perturbation levels, and concerning cosmology at early, intermediate and late times, are then confronted with the huge amount of observational data that astrophysics and cosmology has been able to offer in the last two decades. Theories, scenarios and models that successfully and efficiently pass the above steps are classified as viable and are candidates for the description of Nature, allowing readers to get a clear overview of the state of the art and where the field of modified gravity is likely to go. This work was performed in the framework of the COST European Action “Cosmology and Astrophysics Network for Theoretical Advances and Training Actions” - CANTATA.

This book is a gentle introduction for all those wishing to learn about modern views of the cosmos. Our universe originated in a great explosion – the big bang. For nearly a century cosmologists have studied the aftermath of this explosion: how the universe expanded and cooled down, and how galaxies were gradually assembled by gravity. The nature of the bang itself has come into focus only relatively recently. It is the subject of the theory of cosmic inflation, which was developed in the last few decades and has led to a radically new global view of the universe. Students and other interested readers will find here a non-technical but conceptually rigorous account of modern cosmological ideas - describing what we know, and how we know it. One of the book's central themes is the scientific quest to find answers to the ultimate cosmic questions: Is the universe finite or infinite? Has it existed forever? If not, when and how did it come into being? Will it ever end? The book is based on the undergraduate course taught by Alex Vilenkin at Tufts University. It assumes no prior knowledge of physics or mathematics beyond elementary high school math. The necessary physics background is introduced as it is required. Each chapter includes a list of questions and exercises of varying degree of difficulty. This new edition includes hints for answering the questions and exercises, as well as extensions to the discussions on dark matter, quantum cosmology. A new chapter summarizing the standard cosmological model has also been added.

This book provides a remarkable and complete survey of important questions at the interface between theoretical particle physics and cosmology. After discussing the theoretical and experimental physics revolution that led to the rise of the Standard Model in the past century, the author reviews all the major open puzzles, among them the hierarchy problem, the small value of the cosmological constant, the matter-antimatter asymmetry, and the dark matter enigma, including the state-of-the-art regarding proposed solutions. Also addressed are the rapidly expanding fields of thermal dark matter, cosmological first-order phase transitions and gravitational-wave signatures. In addition, the book presents the original and interdisciplinary PhD research work of the author relating to Weakly-Interacting-Massive-Particles around the TeV scale, which are among the most studied dark matter candidates. Motivated by the absence of experimental evidence for such particles, this thesis explores the possibility that dark matter is much heavier than what is conventionally assumed.

This compilation based upon recent peer-reviewed journal publications encapsulates how the Flat Space Cosmology model (FSC) has become the primary competitor to the inflationary standard model of cosmology. New ideas concerning black holes, dark energy and dark matter are presented and shown to correlate extremely well with astronomical observations. Anyone who follows the fast-changing science of cosmology, has an interest in the latest developments, and would like to know how it is that our universe appears to follow equations one would ordinarily expect for a time-reversed black hole (!), may find this book to be fascinating. Cosmology is the study of how the universe has changed over the great span of time (roughly 14 billion years). Later centuries will look back upon the period from 1990-2030 as a ‘Golden Age’ of theoretical and observational cosmology. It is highly likely that we are on the verge of a deeper understanding of the most mysterious energy (‘dark energy’) and matter (‘dark matter’) comprising the majority of energy and matter in the universe. Some of the material presented in this book is on the cutting edge of dark energy and dark matter theoretical work. This book summarizes, for the first time, the groundbreaking publications of two cosmologists, one from the United States and the other from India, from 2015 thru 2020. During this highly productive period, the authors stealthily published their papers in six different peer-reviewed scientific journals, so that the model could be quietly explored in all aspects before bringing it all together in a single book. This is that book!

The three neutrinos are ghostly elementary particles that exist all across the Universe. Though every second billions of them fly through us, they are extremely hard to detect. We used to think they had no mass, but recently discovered that in fact they have a tiny mass. The quest for the neutrino mass scale and mass ordering (specifying how the three masses are distributed) is an extremely exciting one, and will open the door towards new physics operating at energy scales we can only ever dream of reaching on Earth. This thesis explores the use of measurements of the Cosmic Microwave Background (the oldest light reaching us, a snapshot of the infant Universe) and maps of millions of galaxies to go after the neutrino mass scale and mass ordering. Neutrinos might teach us something about the mysterious dark energy powering the accelerated expansion of the Universe, or about cosmic inflation, which seeded the initial conditions for the Universe. Though extremely baffling, neutrinos are also an exceptionally exciting area of research, and cosmological observations promise to reveal a great deal about these elusive particles in the coming years.

This volume presents cutting-edge research on one of modern cosmology's most intriguing challenges: the observed dipolar anisotropies that appear to conflict with the standard ΛCDM cosmological model. Through its contributed chapters, the book extensively examines multiple lines of evidence suggesting directional preferences in various cosmological observations, from cosmic expansion to galaxy cluster distributions. The work explores two fundamental possibilities: either these dipoles represent genuine spacetime anisotropy, challenging the cosmological principle itself, or they indicate a need to revise our interpretation of the cosmological data and the current models of large-scale structure formation. Both scenarios carry profound implications for our understanding of the universe's fundamental nature and evolution. This comprehensive collection bridges theoretical frameworks with observational evidence, offering fresh perspectives on cosmic isotropy, dark energy, and structure formation. The volume includes detailed analyses of various dipolar signals, their potential systematic origins, and theoretical frameworks that might accommodate these observations. The proceedings appeal to a broad audience of researchers working on both theoretical and observational cosmology, with experience and expertise levels ranging from that of senior researchers to those of postgraduate students. The same is also true for astrophysicists and physicists with expertise other than cosmology.

Primordial Cosmology deals with one of the most puzzling and fascinating topics debated in modern physics - the nature of the Big Bang singularity. The authors provide a self-consistent and complete treatment of the very early Universe dynamics, passing through a concise discussion of the Standard Cosmological Model, a precise characterization of the role played by the theory of inflation, up to a detailed analysis of the anisotropic and inhomogeneous cosmological models. The most peculiar feature of this book is its uniqueness in treating advanced topics of quantum cosmology with a well-traced link to more canonical and pedagogical notions of fundamental cosmology. This book traces clearly the backward temporal evolution of the Universe, starting with the Robertsonndash;Walker geometry and ending with the recent results of loop quantum cosmology in view of the Big Bounce. The reader is accompanied in this journey by an initial technical presentation which, thanks to the fundamental tools given earlier in the book, never seems heavy or obscure.
