Imaging observations of SN1987A at gammaray energies
The Caltech imaging q-ray telescope was launched by balloon from Alice Springs, NT, Australia for observations of SN1987A during the period 18.80-18.87 November 1987 UT. The preliminary results presented here are derived from 8200 seconds of instrument livetime on the supernova and 2500 seconds on the Crab Nebula and pulsar at a float altitude of 37 kin. We have obtained the first images of the...
متن کاملThe Prompt Gamma-Ray and Afterglow Energies of Short-Duration Gamma-Ray Bursts
I present an analysis of the γ-ray and afterglow energies of the complete sample of 17 short-duration GRBs with prompt X-ray follow-up. I find that 80% of the bursts exhibit a linear correlation between their γ-ray fluence and the afterglow X-ray flux normalized to t = 1 d, a proxy for the kinetic energy of the blast wave (FX,1 ∝ F 1.01±0.09 γ ). An even tighter correlation is evident between E...
متن کاملProperties of the thundercloud discharges responsible for terrestrial gammaray flashes
[1] The source of terrestrial gamma-ray flashes (TGFs) has been an active area of research since their discovery by Compton Gamma-Ray Observatory/Burst and Transient Source Experiment in 1994. These intense bursts of gamma rays originate within thunderclouds via the rapid production of relativistic runaway electrons, accelerated by thundercloud/lightning electric fields to multi-MeV energies. R...
متن کاملHighly magnetized region in pulsar wind nebulae and origin of the Crab gammaray flares
The recently discovered gamma-ray flares from the Crab nebula are generally attributed to the magnetic energy release in a highly magnetized region within the nebula. I argue that such a region naturally arises in the polar region of the inner nebula. In pulsar winds, efficient dissipation of the Poynting flux into the plasma energy occurs only in the equatorial belt where the energy is predomi...
متن کاملCorrelations of Prompt and Afterglow Emission in Swift Long and Short Gamma Ray Bursts
Correlation studies of prompt and afterglow emissions from gamma-ray bursts (GRBs) between different spectral bands has been difficult to do in the past because few bursts had comprehensive and intercomparable afterglow measurements. In this paper1 we present a large and uniform data set for correlation analysis based on bursts detected by the Swift mission. For the first time, short and long b...
