Gravity, Cosmology, and Astrophysics : A Journey of Exploration and Discovery with Female Pioneers
This open access book provides graduate students and scientists with fundamental knowledge on the mechanics of granular suspensions as well as on the mathematical and numerical techniques that can be adopted to investigate geophysical flows.To this end, three formidably complex problems (sediment transport, flow-like landslide inception, and gravity currents) are considered.The reader will find a thorough combination of elements of fluid and solid mechanics, rheology, geotechnics, geomorphology, civil, and coastal engineering.The first part of the book introduces the problem of granular suspensions from the mathematical viewpoint, focusing on issues that characterise geophysical flows such as turbulence, the effects of inter-particle contacts, and strong velocity gradients.In the second part, different models that were successfully used to investigate the mechanics of granular suspensions in environmental flows are presented.

Cosmology
This book is unique in the detailed, self-contained, and comprehensive treatment that it gives to the ideas and formulas that are used and tested in modern cosmological research.It divides into two parts, each of which provides enough material for a one-semester graduate course.The first part deals chiefly with the isotropic and homogeneous average universe; the second part concentrates on the departures from the average universe.Throughout the book the author presents detailed analytic calculations of cosmological phenomena, rather than just report results obtained elsewhere by numerical computation.The book is up to date, and gives detailed accounts of topics such as recombination, microwave background polarization, leptogenesis, gravitational lensing, structure formation, and multifield inflation, that are usually treated superficially if at all in treatises on cosmology.Copious references to current research literature are supplied.Appendices include a brief introduction to general relativity, and a detailed derivation of the Boltzmann equation for photons and neutrinos used in calculations of cosmological evolution.Also provided is an assortment of problems.

Relativistic Cosmology
Cosmology has been transformed by dramatic progress in high-precision observations and theoretical modelling.This book surveys key developments and open issues for graduate students and researchers.Using a relativistic geometric approach, it focuses on the general concepts and relations that underpin the standard model of the Universe.Part I covers foundations of relativistic cosmology whilst Part II develops the dynamical and observational relations for all models of the Universe based on general relativity.Part III focuses on the standard model of cosmology, including inflation, dark matter, dark energy, perturbation theory, the cosmic microwave background, structure formation and gravitational lensing.It also examines modified gravity and inhomogeneity as possible alternatives to dark energy.Anisotropic and inhomogeneous models are described in Part IV, and Part V reviews deeper issues, such as quantum cosmology, the start of the universe and the multiverse proposal.Colour versions of some figures are available at www.cambridge.org/9780521381154.

Modern Cosmology
Modern Cosmology, Third Edition provides a detailed introduction to the field of cosmology.Beginning with the smooth, homogeneous universe described by a Friedmann-Lemaître-Robertson-Walker metric, this trusted resource includes careful treatments of dark energy, big bang nucleosynthesis, recombination, and dark matter.The reader is then introduced to perturbations about an FLRW universe: their evolution with the Einstein-Boltzmann equations, their primordial generation by inflation, and their observational consequences: the acoustic peaks in the CMB; the E/B decomposition in polarization; gravitational lensing of the CMB and large-scale structure; and the BAO standard ruler and redshift-space distortions in galaxy clustering. This revised third edition includes updates such as new sections on gravitational waves, line intensity mapping, and emergent analysis techniques; expanded sections of CMB secondaries; and revised figures and pedagogy.These revisions serve to enhance a comprehensive foundational text, as well as provide users with improvements that are aligned with recent advances in the field, as well as modern focuses in the classroom.

Why does cosmology make me cry?
Cosmology can evoke strong emotions because it confronts us with the vastness and complexity of the universe, and our small place within it. The realization of our own insignificance in the grand scheme of the cosmos can be overwhelming and humbling. Additionally, contemplating the mysteries of the universe, such as the origins of the universe or the possibility of other intelligent life forms, can stir up deep existential questions and emotions. Ultimately, the profound nature of cosmology can lead to a sense of awe, wonder, and even a feeling of being deeply connected to something much larger than ourselves, which can be deeply moving.

What is the difference between astronomy and cosmology?
Astronomy is the scientific study of celestial objects such as stars, planets, and galaxies, as well as the phenomena that occur outside the Earth's atmosphere. It focuses on observing and understanding the physical properties and behavior of these objects. On the other hand, cosmology is a branch of astronomy that specifically deals with the origin, evolution, and eventual fate of the universe as a whole. It seeks to understand the large-scale structure and dynamics of the universe, including the nature of dark matter and dark energy, the Big Bang theory, and the formation of galaxies and large-scale cosmic structures. In summary, astronomy focuses on the study of individual celestial objects, while cosmology focuses on the universe as a whole.

Cosmology and String Theory
Cosmology describes the evolution of the Universe and is based on a description of its beginning from quantum fluctuations.String theory is the only known consistent theory of quantum gravity that can deal with the highest energy scales near the Planck energy, relevant for cosmology's beginning.As a result, only string theory can give a fully consistent picture of cosmological origins.This book describes the best current avenues for obtaining cosmology from string theory.It is aimed at graduate students, and also researchers, with some familiarity with cosmology and string theory, however no detailed knowledge is required.
