An Energetic Afterglow from a Distant Stellar Explosion
We present the discovery of radio afterglow emission from the high redshift (z = 6.295) burst GRB050904. The peak flux density for this burst is similar to typical low-redshift gamma-ray bursts (GRB). We further show that beyond a redshift of order unity, the flux density of radio afterglows are largely insensitive to redshift, consistent with predictions. By combining the existing X-ray, near-...
متن کاملGravitational Waves from Stellar Collapse: Correlations to Explosion Asymmetries
The collapse of massive stars not only produces observable outbursts across the entire electromagnetic spectrum but, for Galactic (or near-Galactic) supernovae, detectable signals for ground-based neutrino and gravitational wave detectors. Gravitational waves and neutrinos provide the only means to study the actual engine behind the optical outbursts: the collapsed stellar core. While the neutr...
متن کاملA Two-component Explosion Model for the Giant Flare and Radio Afterglow from Sgr1806-20
The brightest giant flare from the soft γ-ray repeater (SGR) 1806-20 was detected on 2004 December 27. The isotropic-equivalent energy release of this burst is at least one order of magnitude more energetic than those of the two other SGR giant flares. Starting from about one week after the burst, a very bright (∼ 80 mJy), fading radio afterglow was detected. Follow-up observations revealed the...
متن کاملOld stellar populations in distant radio galaxies
I describe the current status of our attempts to determine the age of the oldest known stellar populations at high redshift, in the red mJy radio galaxies 53W091 (z = 1.55) and 53W069 (z = 1.43). During the past year the original conclusion of Dunlop et al. (1996) that 53W091 is > 3 Gyr old has been questioned from two, basically orthogonal directions. First, reports that the near-infrared ligh...
متن کاملThermal explosion theory for shear localizing energetic solids
The behaviour of energetic solids subjected to simple shear loading is modelled to predict ignition. The model is transient, one dimensional and includes effects of thermal diffusion, plastic work and exothermic reaction with one-step irreversible Arrhenius kinetics. A common power-law constitutive model for shear stress which accounts for strain hardening, strain-rate hardening and thermal sof...
