This thesis addresses two very different but equally important topics in the very broad fields of astrophysics and cosmology: (I) the generation of cosmological magnetic fields and (II) gravitational fragmentation of the Cosmic Web. All mathematical developments are completed by illuminating physical interpretations, and the thesis, which is guided by existing observations, is purely theoretical. In part I, the author further develops a magnetogenesis model proposed in the literature, providing an unprecedented level of physical understanding. He demonstrates that the physics of photoionisation is very likely to have premagnetised, at a relevant level, the entire Universe at the early epoch of the formation of the first luminous sources. In part II, the author adapts the tools of plasma spectral theory to the context of gravitational instability of the baryonic gas within the stratified structures of the Cosmic Web. He skillfully derives the wave equation governing the growth of perturbations and explores various equilibrium configurations, in planar and cylindrical geometries characteristic of cosmic walls and filaments, for isothermal and polytropic conditions, with or without an external gravitational background. Clearly structured and written in pedagogical style, this outstanding thesis puts the results into perspective and highlights the merits and limitations of the various approaches explored.

The book entitled “Galaxy Observations to Understand the Structure of the Universe” is according the requirement and need for the information and knowledge from different area of Astronomy, Astrophysics and Science. The night sky appears along with its countless stars and dark patches that are difficult to understand. Humanity has been extremely interested for millennia. We have asked ourselves among the most intense questions mentioned here. What are these points of light? How did they come to be? And what do they tell us about the universe we inhabit? This book seeks to plunge into these questions by focusing on one of the most interesting and complex structures in the cosmos: galaxies. Galaxies are known as the fundamental building blocks of the universe. A vast systems containing billions of stars, gas, dust, stellar remnants and dark matter, all bound together by gravity. The deep understanding about the universe can be achieved when we very explicitly understand the galaxies from its origins in the Big Bang to its eventual fate. This book is prepared to provide a comprehensive overview of the methods and tools used in the observation of the galaxies. This book exhibits what these observations shows about the large-scale structure and evolution of the universe. Chapter 1: Galaxies: Types, Formation and Our Place in the Cosmos We start our journey according to the content of this book which covers an introduction to galaxies. It explored about the different types of galaxies such as spiral, elliptical, and irregular galaxies. Understanding these basic forms and their characteristics sets the stage for deeper exploration. In this chapter, we also focus on our own galaxy, the Milky Way, to provide a familiar context for these cosmic giants. Chapter 2: Tools and Techniques for Observing Galaxies The observation of galaxies requires discreet tools and techniques. In this chapter, various contents about the types of telescopes like optical, radio, infrared, ultraviolet, and X-ray has been covered. For the observational work astronomers use such telescopes to gather data across different wavelengths. We also delve into imaging techniques, high-resolution and multi-wavelength observations, the fascinating phenomenon of gravitational lensing and spectroscopy. Chapter 3: Comprehensive Mapping and Analysis of Galaxy Distribution: Understanding Cosmic Structures and Large-Scale Patterns in the Universe In this chapter, we will understand the large-scale structure of the universe by creating maps of galaxy distribution. We discuss large-scale galaxy surveys like the Sloan Digital Sky Survey (SDSS) and the Dark Energy Survey (DES). How these projects create three-dimensional maps of galaxies, analyze clusters and superclusters, and let out the universe's vast cosmic web. Chapter 4: The Cosmic Web: Dark Matter, Filaments, and Their Role in Shaping Galaxy Formation In this chapter, we provide detailed study of cosmic web and filamentary structure. It deals with the identification and significance of Cosmic Web and Filamentary structures. This chapter also deals with the role of dark matter in their formation and their importance in understanding galaxy formation and evolution. The universe is interconnected by a vast network of filaments and voids known as the cosmic web. Chapter 5: Understanding Redshift: Measurement Techniques and Applications in Three-Dimensional Cosmic Mapping This chapter tells us that mapping the universe it is important to understanding the distances to galaxies and their motion. We discuss the concept of redshift, various measuring techniques for it, and how redshift data provides helps in generating three-dimensional maps that track the evolution of the universe over time. Chapter 6: Exploring Cosmic Mysteries: Evidence for Dark Matter, Gravitational Lensing, and the Role of Dark Energy in Universal Expansion In modern astrophysics the term dark matter and dark energy are the two most intense mysteries. This chapter presents the examinations for the evidence for dark matter in galaxies and techniques for mapping it using gravitational lensing. The role of dark energy in the accelerated expansion of the universe has also been examined. Chapter 7: Galaxy Evolution and Star Formation: Lifecycle, Environmental Impacts, and Star Formation Dynamics in Diverse Galaxy Types Galaxies are dynamic systems that evolve over time. In this chapter, we expand our knowledge about the life cycle of galaxies. The processes of star formation in different types of galaxies. We also explore, how various environmental factors influence galactic evolution. Chapter 8: Galactic Assemblages and Cosmic Voids: Characteristics, Significance, and Distribution Insights Galaxy clusters and cosmic voids tells as about the structure and evolution of the universe. This chapter involved in understanding the characteristics of these massive structures, their significance, and the lessons learned from studying their distribution. Chapter 9: Cutting-Edge Innovations in Galaxy Observation: Techniques, Analytics, and Future Prospects The advancement in the technology enable us to apply enhanced methods of observing galaxies. We explore advanced techniques such as adaptive optics, interferometry, and the use of machine learning and data analysis in astronomy. We are still in que to get such telescopes and missions that promise to revolutionize our understanding of galaxies. Chapter 10: Cosmological Implications: The Role of Galaxies in Understanding the Universe and Constraining Cosmological Parameters As we know that galaxies are important system and provides the understanding of the cosmos and is not just isolated systems. This chapter discusses the role of galaxies in cosmology. It tells us how galaxy observations constrain cosmological parameters. What they let out about the past, present, and future of the universe. Chapter 11: Exploring the Cosmos: Key Discoveries, Case Studies, and Lessons from Galaxy Observations There are many discoveries have shaped our understanding of galaxies and the universe throughout the history of astronomy. We present case studies of unique and interesting galaxies, focus attention on significant discoveries, and reflect on the lessons learned from historical observations. Chapter 12: The Future of Galaxy Observation: Advancements in Technology, Emerging Projects, and the Evolving Understanding of the Universe's Structure Chapter 13: Conclusion The journey to understand galaxies is far from over. It is difficult to come at the end, so we conclude with a look at upcoming projects and missions, technological advances in astronomy, and how our evolving understanding of galaxy observation will continue to illuminate the mysteries of the universe. This main objective of this book is to provide a thorough understanding of galaxies and their significance in the cosmos. We hope that this journey through the universe of galaxies will inspire and enlighten you, whether you are a student, an amateur astronomer, or simply a curious reader. As we look to the stars and beyond, may we continue to expand our horizons and deepen our appreciation for the impressive weaving of the universe.

The modern Persian word for cosmology is "Keyhan-shenakht", which is also the title of a Persian book written more than 800 years ago. The same term can also be found in Old Persian. In spite of this old tradition, modern cosmology is a new~omer within the scientific disciplines in Iran. The cosmology community' is small and not yet well established. Given the spectacular recent advances in observational and theoretical cosmology, the large amount of new observational data which will become available in the near future, and the rapid expansion of the international cosmology community, it was realized that Iran should play a more active role in the exciting human endeavour which cosmology constitutes. This was the main motivation to establish a School on Cosmology in Iran. The plan is to hold a cosmology school every three years somewhere in Iran. The focus of this First School on Cosmology was chosen to be structure formation, a rapidly evolving cornerstone of modern cosmology. The topics of the school were selected in order to give both a broad overview of the current status of cosmological structure formation, and an in-depth dis cussion of the key issues theory of cosmological perturbations and analysis of cosmic microwave anisotropies. The lectures by Blanchard and Sarkar give an overview of homogeneous cosmological models and standard big bang cosmology. In his contribution, Padmanabhan presents a comprehen sive discussion of the growth of cosmological perturbations.

The existence of soft excess emission originating from clusters of galaxies, de ned as em- sion detected below 1 keV in excess over the usual thermal emission from hot intracluster gas (hereafter the ICM) has been claimed since 1996. Soft excesses are particularly - portant to detect because they may (at least partly) be due to thermal emission from the Warm-Hot Intergalactic Medium, where as much as half of the baryons of the Universe could be. They are therefore of fundamental cosmological importance. Soft excess emission has been observed (and has also given rise to controversy) in a number of clusters, mainly raising the following questions: (1) Do clusters really show a soft excess? (2) If so, from what spatial region(s) of the cluster does the soft excess or- inate? (3) Is this excess emission thermal, originating from warm-hot intergalactic gas (at 6 temperatures of?10 K), or non-thermal, in which case several emission mechanisms have been proposed. Interestingly, some of the non-thermal mechanisms suggested to account for soft excess emission can also explain the hard X-ray emission detected in some clusters, for example by RXTE and BeppoSAX (also see Petrosian et al. 2008—Chap. 10, this issue; Rephaeli et al. 2008—Chap. 5, this issue).
