Book Synopsis Gamma-Ray Burst and Afterglow Astronomy 2001 by : G.R. Ricker
Download or read book Gamma-Ray Burst and Afterglow Astronomy 2001 written by G.R. Ricker and published by American Institute of Physics. This book was released on 2003-05-08 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings contains the papers from both the poster and oral presentations presented at the Workshop celebrating the first year of the HETE mission. The HETE mission, launched on 9 October 2000, has dramatically quickened the pace of GRB discoveries. By disseminating accurate burst coordinates to the astronomical community within a minute of the burst onset, HETE has made possible the panchromatic observation of the early, bright phases of the relativistic fireball expansion in several GRB afterglows. The scientific program covered the rapidly expanding range of GRB research, with roughly half of the sessions being devoted to prompt burst emission, and half to burst afterglows, both from observational and theoretical perspectives. In particular, 26 papers presented in the section on the HETE Satellite Mission comprise both a tutorial on the spacecraft and its instruments, as well as a summary of early scientific results. In addition, special sessions, such as the session devoted to soft gamma repeaters, were devoted to future missions and instrumentation.

This has also increased the interest of astronomers in GRBs. This book reviews the research of the last two years and covers the global properties of GRBs, GRB afterglows, GRB host galaxies, cosmology using GRBs, and theories for GRBs and their afterglows. Theoretical and observational aspects are presented as well as tools for the analysis of the data.
Book Synopsis Gamma-Ray Bursts by : Gilbert Vedrenne
Download or read book Gamma-Ray Bursts written by Gilbert Vedrenne and published by Springer Science & Business Media. This book was released on 2009-03-20 with total page 613 pages. 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.

Book excerpt: The diversity of stellar death is revealed in the energy, velocity and geometry of the explosion debris ("ejecta''). Using multi-wavelength observations of gamma-ray burst (GRB) afterglows I show that GRBs, arising from the death of massive stars, are marked by relativistic, collimated ejecta ("jets'') with a wide range of opening angles. These results suggest that various cosmic explosions are powered by a common energy source, an "engine'' (possibly an accreting stellar-mass black hole), with their diverse appearances determined solely by the variable high velocity output. On the other hand, using radio observations I show that local type Ibc core-collapse supernovae generally lack relativistic ejecta and are therefore not powered by engines. Instead, the highest velocity debris in these sources, typically with a velocity lower than 100,000 km/sec, are produced in the (effectively) spherical ejection of the stellar envelope. The relative rates of engine- and collapse-powered explosions suggest that the former account for only a small fraction of the stellar death rate. Using the first radio and submillimeter observations of GRB hosts, I show that some are extreme starburst galaxies with the bursts directly associated with the regions of most intense star formation. I suggest, by comparison to other well-studied samples, that GRBs preferentially occur in sub-luminous, low mass galaxies, undergoing the early stages of a starburst process. If confirmed with future observations, this trend will place GRBs in the forefront of star formation and galaxy evolution studies.

Book Synopsis Toward an Understanding of the Progenitors of Gamma-Ray Bursts by : Joshua S. Bloom
Download or read book Toward an Understanding of the Progenitors of Gamma-Ray Bursts written by Joshua S. Bloom and published by Universal-Publishers. This book was released on 2002 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: The various possibilities for the origin ("progenitors") of gamma-ray bursts (GRBs) manifest in differing observable properties. Through deep spectroscopic and high-resolution imaging observations of some GRB hosts, I demonstrate that well-localized long-duration GRBs are connected with otherwise normal star-forming galaxies at moderate redshifts of order unity. Using high-mass binary stellar population synthesis models, I quantify the expected spatial extent around galaxies of coalescing neutron stars, one of the leading contenders for GRB progenitors. I then test this scenario by examining the offset distribution of GRBs about their apparent hosts making extensive use of ground-based optical data from Keck and Palomar and space-based imaging from the Hubble Space Telescope. The offset distribution appears to be inconsistent with the coalescing neutron star binary hypothesis (and, similarly, black-hole--neutron star coalescences); instead, the distribution is statistically consistent with a population of progenitors that closely traces the ultra-violet light of galaxies. This is naturally explained by bursts which originate from the collapse of massive stars ``collapsars''). This claim is further supported by the unambiguous detections of intermediate-time (approximately three weeks after the bursts) emission ``bumps'' which appear substantially more red than the afterglows themselves. I claim that these bumps could originate from supernovae that occur at approximately the same time as the associated GRB; if true, GRB 980326 and GRB 011121 provide strong observational evidence connecting cosmological GRBs to high-redshift supernovae and implicate massive stars as the progenitors of at least some long-duration GRBs.
Book Synopsis Gamma-Ray Bursts: 15 Years of GRB Afterglows by : Javier Gorosabel
Download or read book Gamma-Ray Bursts: 15 Years of GRB Afterglows written by Javier Gorosabel and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gamma-ray bursts (GRB) are amongst the most energetic phenomena in the Universe. In 1997 (more than 15 years ago), BeppoSAX allowed the detection of the first GRB X-ray afterglow, leading to the detection of afterglows at other wavelengths (optical, radio) in the following years, probing the cosmological distance scale. There are still many other open issues which still need to be addressed, regarding both theoretical and observational aspects: prompt emission and afterglow physics, progenitors (including Pop III stars), host galaxies, multi-messenger information, etc.

Book Synopsis What Are Gamma-Ray Bursts? by : Joshua S. Bloom
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.

Book Synopsis Gamma-Ray Bursts: 30 Years of Discovery by : E.E. Fenimore
Download or read book Gamma-Ray Bursts: 30 Years of Discovery written by E.E. Fenimore and published by American Institute of Physics. This book was released on 2004-10-21 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last thirty years, gamma-ray bursts have grown from an oddity to a central position in astrophysics. Not only are they the largest explosions since the big bang, capable of flooding most of the universe with gamma-rays, but their brilliance serves as a backlight that can illuminate the cosmos far deeper into the early universe than any other object. Their unpredictability has forced researchers to use extreme measures to observe them: completely autonomous satellites and robotic ground-based telescopes. Their bizarre physical properties have pushed us to develop new theories of astrophysical explosions. Topics include: global properties of GRBs; X-ray flashes; ultra-high energy gamma-rays, neutrinos, gravity waves; prompt emission and early afterglows; relativistic jets and polarization; GRB030329; GRB progenitors; GRB connection to supernovae; dark versus bright GRBs; late afterglows; GRBs and cosmology; general observations; general theory; analysis and observation techniques; present satellites; Swift satellite; future satellites; and robotic observing systems.

This book was released on 2013-06-29 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the Proceedings of the Fifth Scientific Meeting of the Spanish Astronomical Society (Sociedad Espanola de Astronomfa, SEA). The meeting was held at the Universidad de Castilla La Mancha in Toledo, from September 9 to 13, 2002. The event brought together 219 participants who pre sented their latest results in many different subjects. In comparison with the previous scientific meetings of the Society, the numbers of oral talks and poster contributions (122 and 64, respectively) are rapidly increasing, confirming that the SEA conferences are becoming a point of reference to assess the interests and achievements of astrophysical research in Spain. During the meeting, the SEA made public the granting of the Prize to the Best Spanish Ph. D. Thesis in As tronomy and Astrophysics for the period 2000-2001 ex aequo to Dr. A. Zurita and Dr. E. Villaver. This is the second time that the SEA is awarding this prize, which aim is to encourage young spanish astrophysicists to pursue a high level scientific career. The Society is indebted to the Universidad de Castilla La Mancha, and, in particular, to the San Pedro Martir staff, for its hospitality. It is also indebted to the Local Organizing Committee for its dedication and the good atmosphere that prevailed at any moment, and to the Scientific Organizing Committee for its excel lent work.
Book Synopsis Formation and Evolution of Black Holes in the Galaxy by : Gerald Edward Brown
Download or read book Formation and Evolution of Black Holes in the Galaxy written by Gerald Edward Brown and published by World Scientific. This book was released on 2003 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: In published papers H A Bethe and G E Brown worked out the collapse of large stars and supernova explosions. They went on to evolve binaries of compact stars, finding that in the standard scenario the first formed neutron star always went into a black hole in common envelope evolution. C-H Lee joined them in the study of black hole binaries and gamma ray bursts. They found the black holes to be the fossils of the gamma ray bursts. From their properties they could reconstruct features of the burst and of the accompanying hypernova explosions. This invaluable book contains 23 papers on astrophysics, chiefly on compact objects, written over 23 years. The papers are accompanied by illuminating commentary. In addition there is an appendix on kaon condensation which the editors believe to be relevant to the equation of state in neutron stars, and to explain why black holes are formed at relatively low masses.
