Dark Energy Explained by Gina Hagler Pdf

Dark energy is a mysterious force causing the universe to expand in an accelerating manner. Although Edwin Hubble discovered observational proof of expansion in 1929, the first direct evidence for dark energy came from supernova observations in the late 1990s. Untangling complex physics theories with accessible language, informative sidebars, and captivating imagery, this text explores the development and evaluation of scientific theories behind dark energy. Students will learn about the tools and methods scientists use to unravel dark energy's origins, dynamics, and effects on the universe.

Supernova by Or Graur Pdf

A concise illustrated introduction to the history and physics of supernovae, the brilliant explosions of stars; with striking color illustrations. Supernovae are the explosions of stars. They are some of the most energetic phenomena in the Universe, rivaling the combined light of billions of stars. Supernovae have been studied for centuries, and they have also made appearances in popular culture: a glimpse of a supernova in a painting provides Sherlock Holmes with a crucial clue, for example. In this volume in the MIT Press Essential Knowledge series, astrophysicist Or Graur offers a concise and accessible introduction to these awe-inspiring astronomical phenomena. Graur explains that a deep observational understanding of supernovae—why and how they shine and how their brightness changes over time—allows us to use them as tools for experiments in astrophysics and physics. A certain type of supernova, for example, brightens and fades in such a predictable manner that we can measure the distances to their host galaxies. We owe our existence to supernovae—they give us iron for our blood and calcium for our bones. But supernovae may also have caused a mass extinction event on Earth 2.6 million years ago. Graur shows how observations of supernovae played a role in the transformation of astronomy from astrology to astrophysics; surveys the tools used to study supernovae today; and describes the lives and deaths of stars and the supernova remnants, neutron stars, and black holes they leave behind. Illustrations in both color and black and white, many from Graur’s own Hubble Space Telescope data, make this account of supernovae particularly vivid.

The Supernova Story by Laurence Marschall Pdf

Astronomers believe that a supernova is a massive explosion signaling the death of a star, causing a cosmic recycling of the chemical elements and leaving behind a pulsar, black hole, or nothing at all. In an engaging story of the life cycles of stars, Laurence Marschall tells how early astronomers identified supernovae, and how later scientists came to their current understanding, piecing together observations and historical accounts to form a theory, which was tested by intensive study of SN 1987A, the brightest supernova since 1006. He has revised and updated The Supernova Story to include all the latest developments concerning SN 1987A, which astronomers still watch for possible aftershocks, as well as SN 1993J, the spectacular new event in the cosmic laboratory.

Physics and Evolution of Supernova Remnants by Jacco Vink Pdf

Written by a leading expert, this monograph presents recent developments on supernova remnants, with the inclusion of results from various satellites and ground-based instruments. The book details the physics and evolution of supernova remnants, as well as provides an up-to-date account of recent multiwavelength results. Supernova remnants provide vital clues about the actual supernova explosions from X-ray spectroscopy of the supernova material, or from the imprints the progenitors had on the ambient medium supernova remnants are interacting with - all of which the author discusses in great detail. The way in which supernova remnants are classified, is reviewed and explained early on. A chapter is devoted to the related topic of pulsar wind nebulae, and neutron stars associated with supernova remnants. The book also includes an extended part on radiative processes, collisionless shock physics and cosmic-ray acceleration, making this book applicable to a wide variety of astronomical sub-disciplines. With its coverage of fundamental physics and careful review of the state of the field, the book serves as both textbook for advanced students and as reference for researchers in the field.

The Age of Radiance by Craig Nelson Pdf

“A thrilling, intense, and disturbing account of the atomic era, from the discovery of X-rays to the tragic meltdown of Japan’s Fukushima Daiichi nuclear power plant…Rich with powerful images and fraught with drama” (The Christian Science Monitor). When Marie Curie, Enrico Fermi, and Edward Teller forged the science of radioactivity, they began a revolution that ran from the nineteenth century through the course of World War II and the Cold War to our current confrontation with the dangers of nuclear power and proliferation. While nuclear science improves our lives, radiation’s invisible powers can trigger cancer and cellular mayhem. Writing with a biographer’s passion, New York Times bestselling author Craig Nelson unlocks one of the great mysteries of the universe. In The Age of Radiance, Nelson illuminates a pageant of fascinating historical figures: Albert Einstein, Niels Bohr, J. Robert Oppenheimer, Curtis LeMay, John F. Kennedy, Robert McNamara, Ronald Reagan, and Mikhail Gorbachev, among others. He reveals how Jewish scientists fleeing Hitler transformed America from a nation that created light bulbs into one that split atoms; Alfred Nobel’s dream of global peace; and how, in our time, emergency workers and utility employees fought to contain life-threatening nuclear reactors. By tracing our complicated relationship with the dangerous energy we unleashed, Nelson discusses how atomic power and radiation are indivisible from our everyday lives. Brilliantly told and masterfully crafted, The Age of Radiance provides a new understanding of a misunderstood epoch in history and restores to prominence the forgotten heroes and heroines who have changed all of our lives for better and for worse. “This is the kind of book that doesn’t just inform you but leaves you feeling smarter.” (The Dallas Morning News).

Open Issues in Core Collapse Supernova Theory by Anthony Mezzacappa,George Michael Fuller Pdf

Efforts to uncover the explosion mechanism of core collapse supernovae and to understand all of their associated phenomena have been ongoing for nearly four decades. Despite this, our theoretical understanding of these cosmic events remains limited; two- and three-dimensional modeling of these events is in its infancy. Most of the modeling efforts over the past four decades have, by necessity, been constrained to spherical symmetry, with the first two-dimensional, albeit simplified, models appearing only during the last decade. Simulations to understand the complex interplay between the turbulent stellar core fluid flow, its magnetic fields, the neutrinos produced in and emanating from the proto-neutron star, the stellar core rotation, and the strong gravitational fields have yet to be performed. Only subsets of these fundamental ingredients have been included in the models thus far, often with approximation.The purpose of this volume is to identify the outstanding issues that remain in order to come to a complete understanding of these important astrophysical events. As the book focuses on open issues rather than the current state of the art in the field ? although the latter will certainly be discussed ? it will remain relevant for some time.

Supernovae by Albert G. Petschek Pdf

For millennia mankind has watched as the heavens move in their stately progression from night to night and from year to year, presaging with their changes the changing seasons. The sun, the moon, and the planets move in what appears to be an unchanging firmament, except occasionally when a new "star" appears. Among the new stars there are comets, novae, and finally supernovae, the subject of this book. Superstitious mankind regarded these events as significant portents and recorded them carefully so that we have records of supernovae that may reach back as far as 1300 B. C. (Clark and Stephenson, 1977; Murdin and Murdin, 1985). The Cygnus Loop, believed to be a 15,000-year-old supernova remnant at a distance of only 800 pc (Chevalier and Seward, 1988), must have awed our ancestors. Tycho's supernova of 1572, at a distance of 2500 pc, had a magnitude of -4. 0, comparable to Venus at its brightest, and Kepler's supernova of 1604 had a magnitude of - 3 or so. Thus the Cygnus Loop supernova might have had a magnitude of - 6 or so, and should have been readily visible in daytime. A supernova in Vela, about 8000 B. C. was comparably close, as was SN 1006, whose magnitude may have been -9. While most of the supernova records come from the Old World, the supernova of 1054 is recorded in at least one petroglyph in the American West.
