Available in PDF, EPUB and Kindle. Book excerpt: Gamma-ray bursts (GRBs) are short and intense emission of soft [gamma]-rays, which have fascinated astronomers and astrophysicists since their unexpected discovery in 1960s. The X-ray/optical/radio afterglow observations confirm the cosmological origin of GRBs, support the fireball model, and imply a long-activity of the central engine. The high-energy [gamma]-ray emission (> 20 MeV) from GRBs is particularly important because they shed some lights on the radiation mechanisms and can help us to constrain the physical processes giving rise to the early afterglows. In this work, we review observational and theoretical studies of the high-energy emission from GRBs. Special attention is given to the expected high-energy emission signatures accompanying the canonical early-time X-ray afterglow that was observed by the Swift X-ray Telescope. We also discuss the detection prospect of the upcoming GLAST satellite and the current ground-based Cerenkov detectors.

Book excerpt: We calculate the GeV spectra of gamma-ray burst afterglows produced by inverse Compton scattering of these objects sub-MeV emission. We improve on earlier treatments by using refined afterglow parameters and new model developments motivated by recent Swift observations. We present time-dependent GeV spectra for standard, constant-parameter models, as well as for models with energy injection and with time-varying parameters, for a range of burst parameters. We evaluate the limiting redshift to which such afterglows can be detected by the GLAST Large Area Telescope, as well as by AGILE.
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 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 High Energy Neutrinos from Gamma Ray Bursts: Theoretical Predictions, Experimental Searches, and Prospects for Detection by : Oindree Banerjee

This book was released on 2020-10-23 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract Gamma-ray bursts (GRBs) are the most luminous transient events in the observed Universe. However, there is no direct observational evidence for what exactly drives a GRB. The most widely accepted model for these cosmic events is the fireball model where it is thought that a substantial fraction of the kinetic energy of the source is converted to gamma-radiation by shock accelerated electrons emitting synchrotron and inverse-Compton radiation. The acceleration of protons in the gamma-ray emitting region of the GRB has been hypothesized as well. In this hadronic acceleration model, it is predicted that protons may interact with gamma-ray photons to produce a burst of neutrinos at energy ∼10^14 eV during prompt emission and energy ∼10^18 eV during afterglow emission. Several experimental searches for these high energy neutrinos have been conducted and no GRB neutrinos have yet been found. The analytical prediction for neutrino flux has been replaced with a more thorough numerical prediction for neutrino flux. The neutron model of GRBs, where only neutrons can escape the GRB and reach Earth as cosmic rays, has been ruled out by the experimental work of IceCube and ANTARES. Upgraded versions of current experiments such as IceCube, ANTARES, ANITA and ARA, as well as new experiments such as KM3NeT, are preparing to probe and further constrain the fireball paradigm of GRB neutrino production. This review includes: Introduction Early theoretical predictions for neutrino fluences due to GRBs Overview of high energy neutrino experiments and related physics Experimental searches for high energy neutrinos from GRBs Prospects for detection of high energy neutrinos from GRBs High Energy Neutrinos from Gamma Ray Bursts: Theoretical Predictions, Experimental Searches, and Prospects for Detection was originally written as a review submitted for my Ph.D. candidacy paper on Nov 23, 2015.

Book excerpt: The Gamma-ray Large Area Space Telescope (GLAST) is an international space mission that will study the cosmos in the energy range 10 keV-300 GeV, the upper end of which is one of the last poorly observed region of the celestial electromagnetic spectrum. The ancestor of the GLAST/LAT was the Energetic Gamma Ray Experiment Telescope (EGRET) detector, which flew onboard the Compton Gamma Ray Observatory (CGRO). The amount of information and the step forward that the high energy astrophysics made thanks to its 9 years of observations are impressive. Nevertheless, EGRET uncovered the tip of the iceberg, raising many questions, and it is in the light of EGRET's results that the great potential of the next generation gamma-ray telescope can be appreciated. GLAST will have an imaging gamma-ray telescope, the Large Area Telescope (LAT) vastly more capable than instruments own previously, as well as a secondary instrument, the GLAST Bursts Monitor, or GBM, to augment the study of gamma-ray bursts. Gamma-Ray Bursts (GRBs) science is one of the most exciting challenges for the GLAST mission, exploring the high energy emission of one of the most intense phenomena in the sky, shading light on various problems: from the acceleration of particles to the emission processes, to more exotic physics like Quantum Gravity effect. In this paper we report the work done so far in the simulation development as well as the study of the LAT sensitivity to GRB.
