A Standard Kinetic Energy Reservoir in Gamma-Ray Burst Afterglows
We present a comprehensive sample of X-ray observations of 41 γ-ray burst (GRB) afterglows, as well as jet opening angles, θj for a subset with measured jet breaks. We show that there is a significant dispersion in the X-ray fluxes, and hence isotropic X-ray luminosities (LX,iso), normalized to t = 10 hr. However, there is a strong correlation between LX,iso and the beaming fractions, fb ≡ [1 −...
متن کاملGamma Ray burst afterglows in the infrared: a standard candle?
Context. Clustering in the luminosity of the afterglows of gamma-ray burst has been reported in the optical and X-ray. Aims. We investigate the possibility that a clustering in the luminosity of the afterglows of gamma-ray burst exists in near infrared (J, H, K bands). We use observations of events occurring from 1997 to the end of 2007. Methods. We correct the gamma-ray burst afterglow light c...
متن کاملGamma-ray Burst Beaming: a Universal Configuration with a Standard Energy Reservoir?
We consider a gamma-ray burst (GRB) model based on an anisotropic fireball with an axisymmetric energy distribution of the form ǫ(θ) ∝ θ, and allow for the observer’s viewing direction being at an arbitrary angle θv with respect to the jet axis. This model can reproduce the key features expected from the conventional on-axis uniform jet models, with the novelty that the achromatic break time in...
متن کاملHigh Energy Spectral Components in Gamma-Ray Burst Afterglows
We investigate two high energy radiation mechanisms, the proton synchrotron and the electron inverse Compton emission, and explore their possible signatures in the broad-band spectra and in the keV to GeV light curves of gamma-ray burst afterglows. We develop a simple analytical approach, allowing also for the effects of photon-photon pair production, and explore the conditions under which one ...
متن کاملGamma-Ray Burst Afterglows
Extended, fading emissions in multi-wavelength are observed following Gamma-ray bursts (GRBs). Recent broadband observational campaigns led by the Swift Observatory reveal rich features of these GRB afterglows. Here we review the latest observational progress and discuss the theoretical implications for understanding the central engine, composition, and geometric configuration of GRB jets, as w...
