Central engine afterglow of Gamma-ray Bursts

چکیده
Before 2004, nearly all GRB afterglow data could be understood in the context of the external shocks model. This situation has changed in the past two years, when it became clear that some afterglow components should be attributed to the activity of the central engine; i.e., the central engine afterglow. We review here the afterglow emission that is directly related to the GRB central engine. Such an interpretation proposed by Katz, Piran & Sari, peculiar in pre-Swift era, has become generally accepted now.

Physical Processes Shaping Gamma-ray Burst X-ray Afterglow Light Curves: Theoretical Implications from the Swift X-ray Telescope Observations
With the successful launch of the Swift Gamma-Ray Burst Explorer, a rich trove of early X-ray afterglow data has been collected by its onboard X-Ray Telescope (XRT). Some interesting features are emerging, including a distinct rapidly decaying component preceding the conventional afterglow component in many sources, a shallow decay component before the more ‘‘normal’’ decay component observed i...
متن کاملSwift Observations of Grb 070110: an Extraordinary X-ray Afterglow Powered by the Central Engine
We present a detailed analysis of Swift multiwavelength observations of GRB 070110 and its remarkable afterglow. The early X-ray light curve, interpreted as the tail of the prompt emission, displays a spectral evolution already seen in other gamma-ray bursts. The optical afterglow shows a shallow decay up to 2 days after the burst, which is not consistent with standard afterglow models. The mos...
متن کاملPrior Emission Model for X-ray Plateau Phase of Gamma-Ray Burst Afterglows
The two-component emission model to explain the plateau phase of the Xray afterglows of gamma-ray bursts (GRBs) is proposed. One component, which is responsible for the plateau and subsequent normal decay phase of the X-ray afterglow, is the prior emission via outflow ejected from the central engine before the main burst. The other is the main outflow, which causes the prompt GRB emission and t...
متن کاملThe Fireball Shock Model of Gamma Ray Bursts
Gamma-ray bursts are thought to be the outcome of a cataclysmic event leading to a relativistically expanding fireball, in which particles are accelerated at shocks and produce nonthermal radiation. We discuss the theoretical predictions of the fireball shock model and its general agreement with observations. Some of the recent work deals with the collimation of the outflow and its implications...
متن کاملGamma-Ray Burst Early Afterglows
The successful launch and operation of NASA’s Swift Gamma-Ray Burst Explorer open a new era for the multi-wavelength study of the very early afterglow phase of gamma-ray bursts (GRBs). GRB early afterglow information is essential to explore the unknown physical composition of GRB jets, the link between the prompt γ-ray emission and the afterglow emission, the GRB central engine activity, as wel...
