Gamma Ray Burst Predictions for the Fermi Gamma Ray Space Telescope
Results of a phenomenological model to estimate the GRB detection rate by the Fermi Gamma ray Space Telescope are reported. This estimate is based on the BATSE 4B GRB fluence distribution, the mean ratio of fluences measured at 100 MeV – 5 GeV with EGRET and at 20 keV – 2 MeV with BATSE, and the mean EGRET GRB spectrum for the 5 EGRET spark-chamber GRBs. For a 10% fluence ratio and a number spe...
متن کاملGamma-ray Pulsar Simulations for the Gamma-ray Large Area Space Telescope (GLAST)
We present here the current status of pulsar simulations for the Large Area Telescope, the main instrument on the GLAST mission. We present PulsarSpectrum, a pulsar simulator that can reproduce with high detail gamma-ray emission from pulsars. PulsarSpectrum takes into account advanced timing effects, e.g. period changes with time, barycentering effects and glitches. Other ancillary tools have ...
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...
متن کاملGamma-ray burst models.
I consider various possibilities for making gamma-ray bursts, particularly from close binaries. In addition to the much-studied neutron star+neutron star and black hole+neutron star cases usually considered good candidates for short-duration bursts, there are also other possibilities. In particular, neutron star+massive white dwarf has several desirable features. These systems are likely to pro...
