Gamma-Ray Bursts: Progress, Problems & Prospects

TLDR
The cosmological gamma-ray burst (GRB) phenomenon is reviewed in this article, where broad observational facts and empirical phenomenological relations of the GRB prompt emission and afterglow are outlined.
Abstract
The cosmological gamma-ray burst (GRB) phenomenon is reviewed. The broad observational facts and empirical phenomenological relations of the GRB prompt emission and afterglow are outlined. A well-tested, successful fireball shock model is introduced in a pedagogical manner. Several important uncertainties in the current understanding of the phenomenon are reviewed, and prospects of how future experiments and extensive observational and theoretical efforts may address these problems are discussed.

LSST: from Science Drivers to Reference Design and Anticipated Data Products

Željko Ivezić, +312 more
- 15 May 2008 - 
TL;DR: The LSST design is driven by four main science themes: probing dark energy and dark matter, taking an inventory of the solar system, exploring the transient optical sky, and mapping the Milky Way.

Gamma-ray bursts

TL;DR: In this article, the interplay between these observations and theoretical models of the prompt gamma-ray burst and its afterglow is reviewed, and a model of the burst's origin and mechanism is proposed.
