Galactic Models of Gamma-Ray Bursts
Gamma-ray bursts (GRBs) continue to confound astrophysicists nearly a quarter century after their discovery (1). Before the launch of CGRO, most scientists thought that GRBs came from magnetic neutron stars residing in a thick disk (having a scale height of up to ∼ 2 kpc) in the Milky Way (2,3). The data gathered by BATSE showed the existence of a rollover in the cumulative brightness distribut...
متن کاملShort gamma-ray bursts near and far.
Progress in understanding the nature of short gamma-ray bursts (GRBs) has been rapid since the discovery of the first afterglows in mid-2005. The emerging picture appears to be of short GRBs, which originate at moderate redshift (a few tenths) and appear in galaxies of all ages. This discovery has been used to argue for their origin in compact binary mergers. However, this population does not d...

متن کاملGamma-ray Bursts from Blast Waves around Galactic Neutron Stars
The remarkable isotropy of classical gamma-ray bursts (GRBs) sampled by the BATSE instrument on GRO (Meegan et al. 1992; Fishman et al. 1993) requires their sources to be located at cosmological distances, in an extended halo of the Galaxy, or in a more local distribution (<∼ 1 − 2 Kpc) which contrives to be almost isotropic about us. Many authors have attributed ”galactic” bursts to violent di...
متن کاملThe Local-Galactic interpretation of the Gamma-Ray Bursts
In this talk, I shall update my 16-year old claim that all the (thousands of) observed GRBs both long and short, repeating or (so far) not come from the surfaces of Galactic neutron stars, often called ’magnetars’, or ’throttled pulsars’.
