The jet break in the X-ray afterglow of gamma ray bursts (GRBs) appears to be correlated to other properties of the X-ray afterglow and the prompt gamma ray emission, but the correlations are at odds with those predicted by the conical fireball (FB) model of GRBs. They are in good agreement, however, with those predicted by the cannonball (CB) model of GRBs

    Fast X-ray Transients (FXTs) are short duration X-ray sources that have timescales of minutes to hours. They have been observed by many instruments, from HEAO-1 to BeppoSAX, however, they are still unexplained. Due to their wide range of observational characteristics, it is suspected that FXTs...

    The observation of X-ray excesses greater than 5 sigma above an assumed model spectrum in approximately 15% of 86 bright bursts observed by BATSE has been verified in recent work. We have looked at a further 64 events, and observe the same behavior of a 15% excess rate in the...

    We describe fully relativistic three dimensional calculations of the slowing down and spreading of a relativistic jet by an external medium like the ISM.

    The origin of GRBs has been a mystery for almost 30 years. The afterglow observed in the last few years enabled redshift determination for a handful of bursts, and the cosmological origin is now firmly established. Though the distance scale is settled, there still remains orders of magnitude...

    Gamma-ray burst astronomy has undergone a revolution in the last three years, spurred by the discovery of fading long-wavelength counterparts. We now know that at least the long duration GRBs lie at cosmological distances with estimated electromagnetic energy release of 10[sup 51]-10[sup 53]...

    X-ray flashes (XRFs) are a new type of fast transient source observed with the BeppoSAX Wide Field Cameras (WFC) at a rate of about four per year. Apart from their large fraction of 2-26 kev X-rays, the bulk properties of these events are similar to those of classical gamma-ray bursts (GRBs). By...

    The brightest transients in the sky, Supernovae and Gamma-Ray Bursts, are associated with the collapse of cores of massive stars. They shine in the optical and in the gamma-ray sky. On theoretical grounds one would expect to see similar events in the x-ray and ultra-violet sky. Here we summarize...
