On the Gamma-Ray Burst Cosmology
Gamma-ray bursts (GRBs) are becoming more and more standardizable candles. Different methods have been proposed to measure cosmology with the relation between the γ-ray energy Eγ of a GRB jet and the peak energy Ep of the νFν spectrum in the burst frame. We compare the procedures and results of these methods. We also discuss the effects from the circumburrsrt density n and the efficiency ηγ of ...
متن کاملOn the future of Gamma-Ray Burst Cosmology
With the understanding that the enigmatic Gamma-Ray Burts (GRBs) are beamed explosions, and with the recently discovered “Ghirlanda-relation”, the dream of using GRBs as cosmological yardsticks may have come a few steps closer to reality. We have investigated possible constraints on cosmological parameters using a simulated future sample of a large number of GRBs inspired by the ongoing SWIFT m...
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...
