Gamma-ray bursts (GRBs) are the most luminous and violent explosions detectable out to the edge of the observable Universe. As soon as their cosmological origin was established, it became apparent that GRBs can serve as powerful probes of the high-redshift Universe.
We discuss the prospects for probing the ancient universe through high‐energy gamma‐ray from GRBs. UV intergalactic radiation fields (IRFs) during cosmic reionization can be probed through multi‐GeV spectral absorption features due to photon‐photon pair production.
Using different IRF models including Pop III stars and consistent with existing observations, we show that spectral Author: S. Inoue, R. Salvaterra, T. Choudhury, A. Ferrara, B. Ciardi, R. Schneider.

Bloom's What Are Gamma Ray Bursts is the second book in the Princeton University Press Frontiers in Physics Series.
It shares the same concise and compact format as the earlier volume on the First Stars and Galaxies in the Universe, together with Deciphering the ancient universe with gamma-ray bursts book same annoyingly small type by: 8.
As the most powerful explosion that occurs in the universe, gamma-ray bursts (GRBs) are one of the most exciting topics being studied in astrophysics. Creating more energy than the Sun does in its entire lifetime, GRBs create a blaze of light that will outshine every other object visible in the sky, enabling us to measure galaxies that are several million years old.

While the mystery of short-duration gamma-ray bursts is still being unraveled, the focus of studies for long-duration gamma-ray bursts has begun to change from understanding the origin of the bursts themselves (which is now fairly well-established) to using them as tools to understand the broader universe.
Book Description. 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.
From the reviews: “In Gamma-Ray Bursts: The Brightest Explosions in the Universe, French gamma-ray astronomers Gilbert Vedrenne and Jean-Luc Atteia have summarized both the observational history and the theoretical understanding of GRBs through Throughout the book, each chapter is packed with references to the original papers .5/5(1).
"This book gives a balanced and up-to-date overview of the field of gamma-ray bursts, one that will be useful for astronomers, physicists, and other scientists.
Until now, there have been no books that I know of that deal with this subject for a broader audience of scientists and educated lay people."—Ralph A.M.J.
Wijers, University of Amsterdam. Astronomers have witnessed gamma-ray bursts (GRBs)—lasting from just fractions of a millisecond to several minutes—as the brightest explosions in the universe.
The blasts' lethal energy output shreds any nearby biological molecules, whether in a functioning organism or somewhere in a planet's environment. Models of the Universe. One of the first cosmological models was the geocentric model developed by the Greek astronomer Ptolemy.
Ptolemy's model of the Universe placed the Earth at the center with the sun and planets located in concentric crystal spheres surrounding Earth. These spheres rotated, causing the sun and planets to appear to rise and set. Gamma-ray bursts are among the most energetic and explosive events in the universe.
They are also short-lived, lasting from a few milliseconds to about a minute. This has made it tough for astronomers to observe a gamma-ray burst in detail.
Gamma-ray bursts were discovered in the late s, but only recently have most astronomers agreed that a large fraction of the bursts originate in the very distant, early Universe. In Deciphering the Ancient Universe with Gamma-Ray Bursts (pp.
(AIP Conference Proceedings; Vol. The third interplanetary by: 1. New chapters cover X-ray emission processes, the interstellar medium, the Solar System, and gamma-ray bursts. The text is supported by over figures, with tables listing the properties of the sources, and more specialized technical points separated in by: Gamma ray bursts (GRB) are the largest known explosions in the Universe; immensely powerful, quick to fade, but usually incredibly far away.
Astronomers with the National Radio Astronomy Observatory got lucky, though, when they analyzed a recent GRB and discovered it was only billion light-years away. Unraveling the mystery of Gamma Ray Bursts (GRBs) is a story filled with international intrigue, fantastic claims, serious back-tracking, and incremental improvements in our understanding of.

One of the Universe's Most Powerful Events, researchers have made great strides in understanding these explosive bursts, but much of their nature. In this tour de force of the ultimate and extreme in astrophysics, renowned astrophysicist and author J.
Craig Wheeler takes us on a breathtaking journey to supernovae, black holes, gamma-ray bursts and adventures in hyperspace. This is no far-fetched science fiction tale, but an enthusiastic exploration of ideas at the cutting edge of current astrophysics.
There is strong evidence that some short-duration gamma-ray bursts occur in systems with no star formation and no massive stars, such as elliptical galaxies and galaxy halos. The favored theory for the origin of most short gamma-ray bursts is the merger of a binary system consisting of two neutron stars.

Absorption spectra of these quasars trace the evolution of intergalactic medium (IGM). Currently, more than 60 quasars have been discovered at z >including about 30 at z > by: 1.

in: deciphering the ancient universe with gamma-ray bursts. International Symposium Deciphering the Ancient Universe with Gamma-Ray Bursts; APR. There are two types of bursts.
Some are short, lasting less than 2 seconds. Others are longer, bursting for as long as seconds. We now think that all Gamma Ray Bursts come from the creation of black holes in distant galaxies.
The two types of bursts come from two different ways to make a black hole. Gamma-ray bursts are usually classified through their high-energy emission into short-duration and long-duration bursts. A third intermediate group has been identified on statistical grounds but its individual properties have not yet been studied in : A.
