This book is a pedagogical guide on how to make computations in direct dark matter (DM) detection. The theory behind the calculation of direct detection cross sections and rates is presented, touching aspects related to elementary particle physics, hadronic physics, nuclear physics, and astrophysics. The book is structured in self-contained sections, covering several topics ranging from the scattering kinematics to the phenomenology of direct DM searches. It follows a model-independent approach, aiming at providing the readers with all that is needed to understand the theory and start their own analysis. Meant for graduate students and researchers with interests in particle physics and phenomenology, it is enriched with several worked examples from standard and non-standard particle DM models. Senior researchers working in different areas related to dark matter, like particle and nuclear physics, astrophysics, and cosmology, find in this booka useful and updated guide for reference.

By the star physicist and author of multiple #1 Sunday Times bestsellers, a major and definitive narrative work on black holes and how they can help us understand the universe. At the heart of our galaxy lies a monster so deadly it can bend space, throwing vast jets of radiation millions of light years out into the cosmos. Its kind were the very first inhabitants of the universe, the black holes.Today, across the universe, at the heart of every galaxy, and dotted throughout, mature black holes are creating chaos. And in a quiet part of the universe, the Swift satellite has picked up evidence of a gruesome death caused by one of these dark powers. High energy X-ray flares shooting out from deep within the Draco constellation are thought to be the dying cries of a white dwarf star being ripped apart by the intense tides of a supermassive black hole ? heating it to millions of degrees as it is shredded at the event horizon.They have the power to wipe out any of the universe's other inhabitants, but no one has ever seen a black hole itself die. But 1.8 billion light years away, the LIGO instruments have recently detected something that could be the closest a black hole gets to death. Gravitational waves given off as two enormous black holes merge together. And now scientists think that these gravitational waves could be evidence of two black holes connecting to form a wormhole ? a link through space and time. It seems outlandish, but today's physicists are daring to think the unthinkable ? that black holes could connect us to another universe.At their very heart, black holes are also where Einstein's Theory of General Relativity is stretched in almost unimaginable ways, revealing black holes as the key to our understanding of the fundamentals of our universe and perhaps all other universes.Join Professors Brian Cox and Jeff Forshaw in exploring our universe's most mysterious inhabitants, how they are formed, why they are essential components of every galaxy, including our own, and what secrets they still hold, waiting to be discovered.

You Are Here is a dazzling exploration of the universe and our relationship to it, as seen through the lens of today's most cutting-edge scientific thinking. Here, for the first time in a single span, is the life of the universe, from quarks to galaxy superclusters and from slime to Homo sapiens. Christopher Potter brilliantly tells the story of how something evolved from nothing and how something became everything; how the universe was once a moment of perfect symmetry and is now 13.7 billion years of history. With wisdom and wonder, Potter traverses the cosmos from its conception to its eventual end?while exploring everything in between.

NEW SCIENCE / SACRED GEOMETRY "In showing the connection between the Hermetic Code and the genetic code, Michael Hayes points to the fact that the essence of evolution can also be found in religion, and therefore in the realm of the evolution of consciousness. . . . What he has discovered could be as important as the original discovery of DNA. Like Jurij Moskvitin and Jeremy Narby, he has created a new paradigm--that is, he is looking at our familiar universe from a new angle and making us aware of magical possibilities." --Colin Wilson, from the Foreword Many have observed the distinct numerical patterns embedded in ancient philosophies and religions from all over the world; others have noted that these same patterns are apparent in many of the theories of groundbreaking science. Michael Hayes reveals that there is a precise code, the Hermetic Code, that connects these patterns--information once known to ancient cultures but apparently lost over time. Mirrored in the structure of this code are the ordering principles of the universe and, intriguingly, also the harmonic ratios of music. Our notions of what is harmonious in music may therefore arise not from an abstract aesthetic sense but rather as a response to an intuition of a fundamental cosmic harmony. The resonance between biology and cosmology shows that life is music, complete with "overtones"--nowhere more strikingly present than in the helical structure of life itself: DNA. MICHAEL HAYES is an administrator at the University of Central England and is the author of The Infinite Harmony. He first recognized a common link between all major religions and esoteric doctrines while working in postrevolutionary Iran, where he was able to observe all the major religions practiced side by side. He lives with his wife and family in Birmingham, England.

Everyone knows that there are things no one can see, for example, the air you're breathing or a black hole, to be more exotic. But not everyone knows that what we can see makes up only 5 percent of the Universe. The rest is totally invisible to us. The invisible stuff comes in two varieties--dark matter and dark energy. One holds the Universe together while the other tears it apart. What these forces really are has been a mystery for as long as anyone has suspected they were there, but the latest discoveries of experimental physics have brought us closer to that knowledge. Particle physicist Dan Hooper takes his readers, with wit, grace, and a keen knack for explaining the toughest ideas science has to offer, on a quest few would ever have expected: to discover what makes up our dark cosmos.

In April 1992, a discovery was made that changed the way we view the world. Dr. George Smoot, distinguished cosmologist and adventurer, whose quest for cosmic knowledge had taken him from the Brazilian rain forest to the South Pole unveiled his momentous discovery, bringing to light the very nature of the universe. For anyone who has ever looked up at the night sky and wondered, for anyone who has ever longed to pull aside the fabric of the universe for a glimpse of what lies behind it. Wrinkles in Time is the story of Smoot's search to uncover the cosmic seeds of the universe. Wrinkles in Time is the Double Helix of cosmology, an intimate look at the inner world of men and women who ask. "Why are we here?" It tells the story of George Smoot's dogged pursuit of the cosmic wrinkles in the frozen wastes of Antarctica, on mountaintops, in experiments borne aloft aboard high-altitude balloons, U-2 spy planes, and finally a space satellite. Wrinkles in Time presents the hard science behind the structured violence of the big bang theory through breathtakingly clear, lucid images and meaningful comparisons. Scientists and nonscientists alike can follow with rapt attention the story of how, in a fiery creation, wrinkles formed in space ultimately to become stars, galaxies, and even greater delicate structures. Anyone can appreciate the implications of a universe whose end is written in its beginnings - whose course developed according to a kind of cosmic DNA, which guided the universe from simplicity and symmetry to ever-greater complexity and structure. As controversial as it may seem today, Wrinkles in Time reveals truths that, in an earlier century, would have doomed its proclaimers to thefiery stake. For four thousand years some people have accepted the Genesis account of cosmic origin; for most of this century, scientists debated two rival scientific explanations known as the steady state and big bang theories. And now, Wrinkles in Time tells what really happened

A fascinating tour of particle physics from Nobel Prize winner Leon Lederman. At the root of particle physics is an invincible sense of curiosity. Leon Lederman embraces this spirit of inquiry as he moves from the Greeks' earliest scientific observations to Einstein and beyond to chart this unique arm of scientific study. His survey concludes with the Higgs boson, nicknamed the God Particle, which scientists hypothesize will help unlock the last secrets of the subatomic universe, quarks and all--it's the dogged pursuit of this almost mystical entity that inspires Lederman's witty and accessible history.

A half century ago, a shocking Washington Post headline claimed that the world began in five cataclysmic minutes rather than having existed for all time; a skeptical scientist dubbed the maverick theory the Big Bang. In this amazingly comprehensible history of the universe, Simon Singh decodes the mystery behind the Big Bang theory, lading us through the development of one of the most extraordinary, important, and awe-inspiring theories in science.

From Brian Greene, one of the world's leading physicists and author of the Pulitzer Prize finalist The Elegant Universe, comes a grand tour of the universe that makes us look at reality in a completely different way.Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton's unchanging realm in which space and time are absolute, to Einstein's fluid conception of spacetime, to quantum mechanics' entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.

The universe comes down to earth in K. C. Cole's Mind Over Matter, a fresh and witty exploration of physics, cosmology, mathematics, astronomy, and more. Like no other science writer, Cole demystifies scientific concepts and humanizes the people who study them. Beginning with a discussion of how "the mind creates reality as well as muddles it," she then peeks into the stories behind science's great minds and into their playful side, and concludes by illuminating the relationship between science and society. Cole's remarkable work brings science to the reader's doorstep, revealing the universe to be elegant, intriguing, and relevant to politics, art, and every dimension of human life.

In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century? Here, too, is a rare, private glimpse of Sagan's thoughts about love, death, and God as he struggled with fatal disease. Ever forward-looking and vibrant with the sparkle of his unquenchable curiosity, Billions & Billions is a testament to one of the great scientific minds of our day.

In the years since its publication in 1988, Stephen Hawking's A Brief History Of Time has established itself as a landmark volume in scientific writing. It has become an international publishing phenomenon, translated into forty languages and selling over nine million copies. The book was on the cutting edge of what was then known about the nature of the universe, but since that time there have been extraordinary advances in the technology of macrocosmic worlds. These observations have confirmed many of Professor Hawkin's theoretical predictions in the first edition of his book, including the recent discoveries of the Cosmic Background Explorer satellite (COBE), which probed back in time to within 300,000 years of the fabric of space-time that he had projected.Eager to bring to his original text the new knowledge revealed by these many observations, as well as his recent research, for this expanded edition Professor Hawking has prepared a new introduction to the book, written an entirely new chapter on the fascinating subject of wormholes and time travel, and updated the original chapters.In addition, to heighten understanding of complex concepts that readers may have found difficult to grasp despite the clarity and wit of Professor Hawking's writing, this edition is enhanced throughout with more than 240 full-color illustrations, including satellite images, photographs made made possible by spectacular technological advance such as the Hubble Space Telescope, and computer generated images of three and four-dimensional realities. Detailed captions clarify these illustrations, enable readers to experience the vastness of intergalactic space, the nature of black holes, and the microcosmic world of particle physics in which matters and antimatter collide.A classic work that now brings to the reader the latest understanding of cosmology, A Brief History Of Time is the story of the ongoing search for t he tantalizing secrets at the heart of time and space.

Awarded the American Astronomical Society (AAS) Rodger Doxsey Travel Prize, and with a foreword by thesis supervisor Professor Shardha Jogee at the University of Texas at Austin, this thesis discusses one of the primary outstanding problems in extragalactic astronomy: how galaxies form and evolve. Galaxies consist of two fundamental kinds of structure: rotationally supported disks and spheroidal/triaxial structures supported by random stellar motions. Understanding the balance between these galaxy components is vital to comprehending the relative importance of the different mechanisms (galaxy collisions, gas accretion and internal secular processes) that assemble and shape galaxies. Using panchromatic imaging from some of the largest and deepest space-based galaxy surveys, an empirical census of galaxy structure is made for galaxies at different cosmic epochs and in environments spanning low to extremely high galaxy number densities. An important result of this work is that disk structures are far more prevalent in massive galaxies than previously thought. The associated challenges raised for contemporary theoretical models of galaxy formation are discussed. The method of galaxy structural decomposition is treated thoroughly since it is relevant for future studies of galaxy structure using next-generation facilities, like the James Webb Space Telescope and the ground-based Giant Magellan Telescope with adaptive optics.

With passion and curiosity, Alan Lightman explores the emotional and philosophical questions raised by recent discoveries in science. He looks at the dialogue between science and religion; the conflict between our human desire for permanence and the impermanence of nature; the possibility that our universe is simply an accident; the manner in which modern technology has separated us from direct experience of the world; and our resistance to the view that our bodies and minds can be explained by scientific logic and laws.Behind all of these considerations is the suggestion--at once haunting and exhilarating--that what we see and understand of the world is only a tiny piece of the extraordinary, perhaps unfathomable whole.

The astounding "New York Times" bestseller--updated with an explanation of the Higgs Boson and its implications--offers new answers to the most basic philosophical questions. With wry humor and wonderfully clear explanations, Krauss goes back to the beginning of the beginning.

The bestselling author of The Elegant Universe and The Fabric of the Cosmos tackles perhaps the most mind-bending question in modern physics and cosmology: Is our universe the only universe?There was a time when "universe" meant all there is. Everything. Yet, a number of theories are converging on the possibility that our universe may be but one among many parallel universes populating a vast multiverse. Here, Briane Greene, one of our foremost physicists and science writers, takes us on a breathtaking journey to a multiverse comprising an endless series of big bangs, a multiverse with duplicates of every one of us, a multiverse populated by vast sheets of spacetime, a multiverse in which all we consider real are holographic illusions, and even a multiverse made purely of math--and reveals the reality hidden within each.Using his trademark wit and precision, Greene presents a thrilling survey of cutting-edge physics and confronts the inevitable question: How can fundamental science progress if great swaths of reality lie beyond our reach? The Hidden Reality is a remarkable adventure through a world more vast and strange than anything we could have imagined.
