DOWNLOAD EBOOKIntroducing astrochemistry to a wide audience, this book describes how molecules formed in chemical reactions occur in a range of environments in interstellar and circumstellar space, from shortly after the Big Bang up to the present epoch. Stressing that chemistry in these environments needs to be driven, it helps identify these drivers and the various chemical networks that operate giving rise to signature molecules that enable the physics of the region to be better understood. The book emphasises, in a non-mathematical way, the chemistry of the Milky Way Galaxy and its planet-forming regions, describes how other galaxies may have rather different chemistries and shows how chemistry was important even in the Early Universe when most of the elements had yet to be formed. This book will appeal to anyone with a general interest in chemistry, from students to professional scientists working in interdisciplinary areas and non-scientists fascinated by the evolving and exciting story of chemistry in the cosmos.

DOWNLOAD EBOOKThis book provides a comprehensive survey of modern molecular astrophysics. It includes an introduction to molecular spectroscopy and then addresses the main areas of current molecular astrophysics, including galaxy formation, star forming regions, mass loss from young as well as highlyevolved stars and supernovae, starburst galaxies plus the tori and discs near the central engines of active galactic nuclei. All chapters have been written by invited authors who are acknowledged experts in their fields. The thorough editorial process has ensured a uniformly high standard ofexposition and a coherent style. The book is unique in giving a detailed view of its wide-ranging subject. It will provide the standard introduction for research students in molecular astrophysics. The book will be read by research astronomers and astrophysicists who wish to broaden the basis oftheir knowledge or are moving their activities into this burgeoning field. It will enable chemists to learn the astrophysics most related to chemistry as well as instruct physicists about the molecular processes most important in astronomy.

DOWNLOAD EBOOKAmong the different structures of the universe exists what we call the interstellar medium (ISM). It is a place where gas and dust coexist and interact in perfect harmony. In this medium, molecular hydrogen is the most abundant gaseous species and by far the most important one. It is the principal constituent of three of four molecules essential to the existence of life: water, methane, amine and carbon monoxide. The physico-chemistry of the ISM that leads to the formation of new molecules is divided in two: the gas-phase reactions and the gas-dust reactions. The second one being the most efficient route of molecular hydrogen in space. This thesis work is an experimental contribution to study the interaction and the formation of molecular hydrogen on the surface of amorphous water ice surfaces covering dust grains in dark clouds. For this, by uniting ultra-high vacuum techniques, cryogenic systems, atomic and molecular beams, mass spectroscopy and modelling, several experiments have been conducted by using the FOMOLISM experimental set-up (FORmation of MOLecules in the InterStellar Medium).

DOWNLOAD EBOOKDescribing interstellar matter in our galaxy in all of its various forms, this book also considers the physical and chemical processes that are occurring within this matter. The first seven chapters present the various components making up the interstellar matter and detail the ways that we are able to study them. The following seven chapters are devoted to the physical, chemical and dynamical processes that control the behaviour of interstellar matter. These include the instabilities and cloud collapse processes that lead to the formation of stars. The last chapter summarizes the transformations that can occur between the different phases of the interstellar medium. Emphasizing methods over results, The Interstellar Medium is written for graduate students, for young astronomers, and also for any researchers who have developed an interest in the interstellar medium.

DOWNLOAD EBOOKThis book focuses on the most recent, relevant, comprehensive and significant aspects in the well-established multidisciplinary field Laboratory Astrophysics. It focuses on astrophysical environments, which include asteroids, comets, the interstellar medium, and circumstellar and circumplanetary regions. Its scope lies between physics and chemistry, since it explores physical properties of the gas, ice, and dust present in those systems, as well as chemical reactions occurring in the gas phase, the bare dust surface, or in the ice bulk and its surface. Each chapter provides the necessary mathematical background to understand the subject, followed by a case study of the corresponding system. The book provides adequate material to help interpret the observations, or the computer models of astrophysical environments. It introduces and describes the use of spectroscopic tools for laboratory astrophysics. This book is mainly addressed to PhD graduates working in this field or observers and modelers searching for information on ice and dust processes.

DOWNLOAD EBOOKThis is a comprehensive and richly illustrated textbook on the astrophysics of the interstellar and intergalactic medium--the gas and dust, as well as the electromagnetic radiation, cosmic rays, and magnetic and gravitational fields, present between the stars in a galaxy and also between galaxies themselves. Topics include radiative processes across the electromagnetic spectrum; radiative transfer; ionization; heating and cooling; astrochemistry; interstellar dust; fluid dynamics, including ionization fronts and shock waves; cosmic rays; distribution and evolution of the interstellar medium; and star formation. While it is assumed that the reader has a background in undergraduate-level physics, including some prior exposure to atomic and molecular physics, statistical mechanics, and electromagnetism, the first six chapters of the book include a review of the basic physics that is used in later chapters. This graduate-level textbook includes references for further reading, and serves as an invaluable resource for working astrophysicists. Essential textbook on the physics of the interstellar and intergalactic medium Based on a course taught by the author for more than twenty years at Princeton University Covers radiative processes, fluid dynamics, cosmic rays, astrochemistry, interstellar dust, and more Discusses the physical state and distribution of the ionized, atomic, and molecular phases of the interstellar medium Reviews diagnostics using emission and absorption lines Features color illustrations and detailed reference materials in appendices Instructor's manual with problems and solutions (available only to teachers)

DOWNLOAD EBOOKThis book provides a comprehensive account of the current status of molecular hydrogen medicine, a young field that emerged with the discovery that inhalation of hydrogen gas leads to the elimination of harmful reactive oxygen species in rats. Various physiologic effects have since been demonstrated, and possible medical applications identified. Numerous clinical projects have now been undertaken, yielding startling results. Despite this, molecular hydrogen medicine remains underappreciated among the medical community at large. The author aims to rectify this situation by fairly but critically evaluating the potential clinical benefits based on the latest scientific research. In addition, the observed physiological effects of hydrogen gas are considered within the broad context of the evolution of life on earth, offering new perspectives and helping to place molecular hydrogen medicine legitimately within the framework of life sciences. Written in an accessible manner, the book will be of value to students, researchers, clinicians, and the general public.
