Download or read book What Are Gamma Ray Bursts written by Joshua S. Bloom and published by Princeton University Press. This book was released on 2011-01-10 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: A brief, cutting-edge introduction to the brightest cosmic phenomena known to science Gamma-ray bursts are the brightest—and, until recently, among the least understood—cosmic events in the universe. Discovered by chance during the cold war, these evanescent high-energy explosions confounded astronomers for decades. But a rapid series of startling breakthroughs beginning in 1997 revealed that the majority of gamma-ray bursts are caused by the explosions of young and massive stars in the vast star-forming cauldrons of distant galaxies. New findings also point to very different origins for some events, serving to complicate but enrich our understanding of the exotic and violent universe. What Are Gamma-Ray Bursts? is a succinct introduction to this fast-growing subject, written by an astrophysicist who is at the forefront of today's research into these incredible cosmic phenomena. Joshua Bloom gives readers a concise and accessible overview of gamma-ray bursts and the theoretical framework that physicists have developed to make sense of complex observations across the electromagnetic spectrum. He traces the history of remarkable discoveries that led to our current understanding of gamma-ray bursts, and reveals the decisive role these phenomena could play in the grand pursuits of twenty-first century astrophysics, from studying gravity waves and unveiling the growth of stars and galaxies after the big bang to surmising the ultimate fate of the universe itself. What Are Gamma-Ray Bursts? is an essential primer to this exciting frontier of scientific inquiry, and a must-read for anyone seeking to keep pace with cutting-edge developments in physics today.

Download or read book Gamma ray Bursts written by Chryssa Kouveliotou and published by Cambridge University Press. This book was released on 2012-11-22 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cosmic gamma ray bursts (GRBs) have fascinated scientists and the public alike since their discovery in the late 1960s. Their story is told here by some of the scientists who participated in their discovery and, after many decades of false starts, solved the problem of their origin. Fourteen chapters by active researchers in the field present a detailed history of the discovery, a comprehensive theoretical description of GRB central engine and emission models, a discussion of GRB host galaxies and a guide to how GRBs can be used as cosmological tools. Observations are grouped into three sets from the satellites CGRO, BeppoSAX and Swift, and followed by a discussion of multi-wavelength observations. This is the first edited volume on GRB astrophysics that presents a fully comprehensive review of the subject. Utilizing the latest research, Gamma-ray Bursts is an essential desktop companion for graduate students and researchers in astrophysics.

Book excerpt: Astrophysics has always been a captivating field, delving into the mysteries of the universe and providing glimpses into the workings of celestial objects. However, it is in the realm of high-energy astrophysics that the universe truly reveals its most extreme phenomena. From quasars to gamma-ray bursts, this subchapter explores the historical milestones that have unraveled the mysteries of high-energy astrophysics. In the early 20th century, the study of astrophysics was primarily focused on the visible light emitted by stars and galaxies. It wasn't until 1932 that the first cosmic rays, highly energetic particles from space, were discovered by physicist Victor Hess. This groundbreaking observation hinted at the existence of high-energy phenomena beyond the reach of traditional telescopes. The discovery of the first X-ray source outside our solar system in 1962 marked a turning point in high-energy astrophysics. Astronomers soon realized that X-rays and gamma-rays, with their much higher energies than visible light, could provide vital information about the most energetic processes in the universe. Exploratory missions, such as the Uhuru satellite launched in 1970, opened a new window for studying high-energy astrophysics. The birth of X-ray astronomy gave rise to incredible findings. In 1967, the first X-ray pulsar, a rapidly rotating neutron star, was discovered. This revelation paved the way for understanding the behavior of matter under extreme gravitational forces. Subsequently, in 1974, the discovery of the first X-ray binary system, where a compact object accretes matter from a companion star, provided further insights into the dynamics of high-energy processes. The 1990s marked a new era with the launch of the Compton Gamma Ray Observatory. This satellite enabled astronomers to observe gamma-ray bursts, the most energetic events in the universe, for the first time. These fleeting bursts of gamma-rays, lasting only a few seconds, puzzled scientists and sparked a race to understand their origins. It wasn't until 1997 that the first optical afterglow of a gamma-ray burst was detected, leading to the realization that these cataclysmic events were associated with the explosive deaths of massive stars. With the advent of space-based observatories like the Chandra X-ray Observatory and the Fermi Gamma-ray Space Telescope, high-energy astrophysics has continued to push the boundaries of our knowledge. These observatories have revealed the existence of supermassive black holes at the centers of galaxies, shedding light on their role in the evolution of cosmic structures.

Available in PDF, EPUB and Kindle. Book excerpt: Since their discovery was first announced in 1973, gamma-ray bursts (GRBs) have been among the most fascination objects in the universe. While the initial mystery has gone, the fascination continues, sustained by the close connection linking GRBs with some of the most fundamental topics in modern astrophysics and cosmology. Both authors have been active in GRB observations for over two decades and have produced an outstanding account on both the history and the perspectives of GRB research.

Available in PDF, EPUB and Kindle. Book excerpt: Gamma-ray bursts are the most violent events since the birth of the universe. They are about ten times more energetic than the most powerful supernovae. At their peak, gamma-ray bursts are the brightest objects in space, about 100,000 times brighter than an entire galaxy. And yet until recently these titanic eruptions were the most mysterious events in astronomy. In The Biggest Bangs, astrophysicist Jonathan Katz offers a fascinating account of the scientific quest to unravel the mystery of these incredible phenomena. With an eye for colorful detail and a talent for translating scientific jargon into plain English, Katz ranges from the accidental discovery of gamma-ray bursts (by a Cold War satellite system monitoring the Nuclear Test Ban Treaty) to the frustrating but ultimately successful efforts to localize these bursts in distant galaxies. He describes the theories, the equipment (the most recent breakthrough was made with a telescope you could carry under your arm), and the pioneers who have finally begun to explain these strange bursts. And along the way, he offers important lessons about science itself, arguing that "small science" is as valuable as institutionalized "big science," that observations are more the product of advances in technology than of theory, and that theory is only "the concentrated essence of experiment." With the advent of the space age a mere 40 years ago, we have grown used to strangeness in the universe--and confident in science's ability to explain it. In The Biggest Bangs, Jonathan Katz shows that there are still wonders out there that exceed the bounds of our imagination and defy our ability to understand them.

Available in PDF, EPUB and Kindle. Book excerpt: The IAU Symposium No. 55 on 'X-Ray and Gamma-Ray Astronomy' has occurred, not entirely by coincidence, at an important moment in the development of these new branches of observational astronomy. In X-ray astronomy the data from the first X-ray observatory UHURU have contributed to a new view of the X-ray sky and a new conception of the nature and properties of galactic and extragalactic X-ray sources. In gamma-ray astronomy the exciting and often controversial nature of the results underlines the importance of the forthcoming launch of SAS-B, the first orbiting y-ray observatory. As Bruno Rossi reminds us (p. I), the Symposium occurred almost exactly ten years after the first detection of the X-ray star Sco X-I. During this time we have moved from the detection of a handful of the nearest and brightest sources to the detailed study of the nature of stellar sources in the farthest reaches of our own galaxy and in external galaxies of the local group. The detection of pulsating X-ray sources in bi nary systems permits the measurement of pulsation periods, and orbital parameters with precisions comparable to any yet achieved with traditional observational techniques. The strong indications that most X-ray sources are extremely compact objects give us confidence that X-ray astronomy will playa significant and possibly decisive role in the study of stars near the end point of stellar evolution.
